Folding Photons  

Science Conference Proceedings (OSTI)

Scientists have shown that wrinkles and folds can be used to maximize the absorption of low-energy photons by efficiently redirecting them into a thin absorbing film. This inexpensive technique for structuring photonic substrates could be used to increase the efficiency of many organic photovoltaic cells.

Folded waveguide coupler  

DOE Patents (OSTI)

A resonant cavity waveguide coupler for ICRH of a magnetically confined plasma. The coupler consists of a series of inter-leaved metallic vanes disposed within an enclosure analogous to a very wide, simple rectangular waveguide that has been ''folded'' several times. At the mouth of the coupler, a polarizing plate is provided which has coupling apertures aligned with selected folds of the waveguide through which rf waves are launched with magnetic fields of the waves aligned in parallel with the magnetic fields confining the plasma being heated to provide coupling to the fast magnetosonic wave within the plasma in the frequency usage of from about 50 to 200 mHz. A shorting plate terminates the back of the cavity at a distance approximately equal to one-half the guide wavelength from the mouth of the coupler to ensure that the electric field of the waves launched through the polarizing plate apertures are small while the magnetic field is near a maximum. Power is fed into the coupler folded cavity by means of an input coaxial line feed arrangement at a point which provides an impedance match between the cavity and the coaxial input line.

Protein Folding as a Physical Stochastic Process  

E-Print Network (OSTI)

We model protein folding as a physical stochastic process as follows. The unfolded protein chain is treated as a random coil described by SAW (self-avoiding walk). Folding is induced by hydrophobic forces and other interactions, such as hydrogen bonding, which can be taken into account by imposing conditions on SAW. The resulting model is termed CSAW (conditioned self-avoiding walk. Conceptually, the mathematical basis is a generalized Langevin equation. In practice, the model is implemented on a computer by combining SAW and Monte Carlo. To illustrate the flexibility and capabilities of the model, we consider a number of examples, including folding pathways, elastic properties, helix formation, and collective modes.

Mechanical Models of Fault-Related Folding  

SciTech Connect

The subject of the proposed research is fault-related folding and ground deformation. The results are relevant to oil-producing structures throughout the world, to understanding of damage that has been observed along and near earthquake ruptures, and to earthquake-producing structures in California and other tectonically-active areas. The objectives of the proposed research were to provide both a unified, mechanical infrastructure for studies of fault-related foldings and to present the results in computer programs that have graphical users interfaces (GUIs) so that structural geologists and geophysicists can model a wide variety of fault-related folds (FaRFs).

Exploring the mechanisms of protein folding  

E-Print Network (OSTI)

Neither of the two prevalent theories, namely thermodynamic stability and kinetic stability, provides a comprehensive understanding of protein folding. The thermodynamic theory is misleading because it assumes that free energy is the exclusive dominant mechanism of protein folding, and attributes the structural transition from one characteristic state to another to energy barriers. Conversely, the concept of kinetic stability overemphasizes dominant mechanisms that are related to kinetic factors. This article explores the stability condition of protein structures from the viewpoint of meso-science, paying attention to the compromise in the competition between minimum free energy and other dominant mechanisms. Based on our study of complex systems, we propose that protein folding is a meso-scale, dissipative, nonlinear and non-equilibrium process that is dominated by the compromise between free energy and other dominant mechanisms such as environmental factors. Consequently, a protein shows dynamic structures,...

Statistical Mechanics Model for Protein Folding  

E-Print Network (OSTI)

We present a novel statistical mechanics formalism for the theoretical description of the process of protein folding$\\leftrightarrow$unfolding transition in water environment. The formalism is based on the construction of the partition function of a protein obeying two-stage-like folding kinetics. Using the statistical mechanics model of solvation of hydrophobic hydrocarbons we obtain the partition function of infinitely diluted solution of proteins in water environment. The calculated dependencies of the protein heat capacities upon temperature are compared with the corresponding results of experimental measurements for staphylococcal nuclease and metmyoglobin.

Chaperonins promote the proper folding of newly translated proteins and proteins that have been stress-denatured-meaning they've lost their structure-by encapsulating them inside a protective chamber formed from two rings of molecular complexes stacked back-to-back. There are two classes of chaperonins, group I found in prokaryotes and group II found in eukaryotes and archaea (organisms with no cell membrane or internal membrane-bound organelles). Much of the basic architecture has been evolutionarily preserved (conserved) across these two classes but they do differ in how the protective chamber is opened to accept proteins and closed to fold them. Whereas group I chaperonins require a detachable ring-shaped molecular lid to open and close the chamber, group II chaperonins have a built-in lid.

Concentration-Temperature Superposition of Helix Folding Rates in Gelatin  

E-Print Network (OSTI)

We study the kinetics of helix-coil transition in water solutions of gelatin (collagen protein) by optical rotation techniques combined with thermal characterization. By examining the rates of secondary helix folding, and covering a very wide range of solution concentrations, we are able to identify a universal exponential dependence of folding rate on concentration and quench temperature. We demonstrate a new concentration-temperature superposition of data at all temperatures and concentrations, and build the corresponding master curve. The results support the concept of a diffuse helix-coil transition. We find no concentration dependance of the normalized rate constant, suggesting first order (single) kinetics of secondary helix folding dominate in the early stages of renaturation.

Thermodynamics of Protein Folding from Coarse-Grained Models' Perspectives  

E-Print Network (OSTI)

Folding and aggregation of proteins, the interaction between proteins and membranes, as well as the adsorption of organic soft matter to inorganic solid substrates belong to the most interesting challenges in understanding structure and function of complex macromolecules. This is reasoned by the interdisciplinary character of the associated questions ranging from the molecular origin of the loss of biological functionality as, for example, in Alzheimer's disease to the development of organic circuits for biosensory applications. In this lecture, we focus on the analysis of mesoscopic models for protein folding, aggregation, and hybrid systems of soft and solid condensed matter. The simplicity of the coarse-grained models allows for a more universal description of the notoriously difficult problem of protein folding. In this approach, classifications of structure formation processes with respect to the conformational pseudophases are possible. This is similar in aggregation and adsorption processes, where the individual folding propensity is influenced by external forces. The main problem in studies of conformational transitions is that the sequences of amino acids proteins are built up of are necessarily of finite length and, therefore, a thermodynamic limit does not exist. Thus, structural transitions are not phase transitions in the strict thermodynamic sense and the analysis of pseudouniversal aspects is intricate, as apparently small-system effects accompany all conformational transitions and cannot be neglected.

ORIGAMI: DELINEATING HALOS USING PHASE-SPACE FOLDS  

SciTech Connect

We present the ORIGAMI method of identifying structures, particularly halos, in cosmological N-body simulations. Structure formation can be thought of as the folding of an initially flat three-dimensional manifold in six-dimensional phase space. ORIGAMI finds the outer folds that delineate these structures. Halo particles are identified as those that have undergone shell-crossing along three orthogonal axes, providing a dynamical definition of halo regions that is independent of density. ORIGAMI also identifies other morphological structures: particles that have undergone shell-crossing along 2, 1, or 0 orthogonal axes correspond to filaments, walls, and voids, respectively. We compare this method to a standard friends-of-friends halo-finding algorithm and find that ORIGAMI halos are somewhat larger, more diffuse, and less spherical, though the global properties of ORIGAMI halos are in good agreement with other modern halo-finding algorithms.

Strong Nernst-Ettingshausen effect in folded graphene  

E-Print Network (OSTI)

We study electronic transport in graphene under the influence of a transversal magnetic field $\\f{B}(\\f{r})=B(x)\\f{e}_z$ with the asymptotics $B(x\\to\\pm\\infty)=\\pm B_0$, which could be realized via a folded graphene sheet in a constant magnetic field, for example. By solving the effective Dirac equation, we find robust modes with a finite energy gap which propagate along the fold -- where particles and holes move in opposite directions. Exciting these particle-hole pairs with incident photons would then generate a nearly perfect charge separation and thus a strong magneto-thermoelectric (Nernst-Ettingshausen) or magneto-photoelectric effect -- even at room temperature.

Directed transport as a mechanism for protein folding in vivo  

E-Print Network (OSTI)

We propose a model for protein folding in vivo based on a Brownian-ratchet mechanism in the multidimensional energy landscape space. The device is able to produce directed transport taking advantage of the assumed intrinsic asymmetric properties of the proteins and employing the consumption of energy provided by an external source. Through such a directed transport phenomenon, the polypeptide finds the native state starting from any initial state in the energy landscape with great efficacy and robustness, even in the presence of different type of obstacles. This model solves Levinthal's paradox without requiring biased transition probabilities but at the expense of opening the system to an external field.

Reliable Protein Folding on Complex Energy Landscapes: The Free Energy Reaction Path  

E-Print Network (OSTI)

ABSTRACT A theoretical framework is developed to study the dynamics of protein folding. The key insight is that the search for the native protein conformation is influenced by the rate r at which external parameters, such as temperature, chemical denaturant, or pH, are adjusted to induce folding. A theory based on this insight predicts that 1), proteins with complex energy landscapes can fold reliably to their native state; 2), reliable folding can occur as an equilibrium or out-of-equilibrium process; and 3), reliable folding only occurs when the rate r is below a limiting value, which can be calculated from measurements of the free energy. We test these predictions against numerical simulations of model proteins with a single energy scale.

Three-fold diffraction symmetry in epitaxial graphene and the SiC substrate

We find that the graphene diffraction spots from 2 and 3 atomic layers of graphene have 3-fold symmetry consistent with AB (Bernal or rhombohedral) stacking of the layers. On the contrary, graphene diffraction spots from the buffer layer and monolayer graphene have apparent 6-fold symmetry, although the 3-fold nature of the satellite spots indicates a more complex periodicity in the graphene sheets.

Type A N-fold Supersymmetry and Generalized Bender-Dunne Polynomials  

E-Print Network (OSTI)

We derive the necessary and sufficient condition for Type A N-fold supersymmetry by direct calculation of the intertwining relation and show the complete equivalence between this analytic construction and the sl(2) construction based on quasi-solvability. An intimate relation between the pair of algebraic Hamiltonians is found. The classification problem on Type A N-fold supersymmetric models is investigated by considering the invariance of both the Hamiltonians and N-fold supercharge under the GL(2,K) transformation. We generalize the Bender-Dunne polynomials to all the Type A N-fold supersymmetric models without requiring the normalizability of the solvable sector. Although there is a case where weak orthogonality of them is not guaranteed, this fact does not cause any difficulty on the generalization. It is shown that the anti-commutator of the Type A N-fold supercharges is expressed as the critical polynomial of them in the original Hamiltonian, from which we establish the complete Type A N-fold superalgebra. A novel interpretation of the critical polynomials in view of polynomial invariants is given.

3 3 Rick Russell, Ian S. Millett, Sebastian Doniach and Daniel Herschlag Stanford University One goal of genome projects is to systematically identify genes (1,2). The best current knowledge indicates that humans carry approximately 35000 genes. This number is an estimate that varies from expert to expert and range up to 100,000 (3-5). To anyone who has taken an elementary biology class, this ambiguity must seem strange. How hard can it be to count genes? After all, don't cells translate genes into proteins? Counting genes should be as easy as counting proteins. In fact, most estimates for the number of genes in the human genome exploit this strategy with researchers developing various ways of directly or indirectly counting proteins (6-10). The fundamental problem then is in the definition of a gene. A gene encodes an action - and not all the action in a cell is in the protein.

Structural proteomics of minimal organisms: conservation ofprotein fold usage and evolutionary implications  

SciTech Connect

Background: Determining the complete repertoire of proteinstructures for all soluble, globular proteins in a single organism hasbeen one of the major goals of several structural genomics projects inrecent years. Results: We report that this goal has nearly been reachedfor several "minimal organisms"--parasites or symbionts with reducedgenomes--for which over 95 percent of the soluble, globular proteins maynow be assigned folds, overall 3-D backbone structures. We analyze thestructures of these proteins as they relate to cellular functions, andcompare conservation off old usage between functional categories. We alsocompare patterns in the conservation off olds among minimal organisms andthose observed between minimal organisms and other bacteria. Conclusion:We find that proteins performing essential cellular functions closelyrelated to transcription and translation exhibit a higher degree ofconservation in fold usage than proteins in other functional categories.Folds related to transcription and translation functional categories werealso over represented in minimal organisms compared to otherbacteria.

Techniques for modeling and analyzing RNA and protein folding energy landscapes  

E-Print Network (OSTI)

RNA and protein molecules undergo a dynamic folding process that is important to their function. Computational methods are critical for studying this folding pro- cess because it is difficult to observe experimentally. In this work, we introduce new computational techniques to study RNA and protein energy landscapes, includ- ing a method to approximate an RNA energy landscape with a coarse graph (map) and new tools for analyzing graph-based approximations of RNA and protein energy landscapes. These analysis techniques can be used to study RNA and protein fold- ing kinetics such as population kinetics, folding rates, and the folding of particular subsequences. In particular, a map-based Master Equation (MME) method can be used to analyze the population kinetics of the maps, while another map analysis tool, map-based Monte Carlo (MMC) simulation, can extract stochastic folding pathways from the map. To validate the results, I compared our methods with other computational meth- ods and with experimental studies of RNA and protein. I first compared our MMC and MME methods for RNA with other computational methods working on the com- plete energy landscape and show that the approximate map captures the major fea- tures of a much larger (e.g., by orders of magnitude) complete energy landscape. Moreover, I show that the methods scale well to large molecules, e.g., RNA with 200+ nucleotides. Then, I correlate the computational results with experimental findings. I present comparisons with two experimental cases to show how I can pre- dict kinetics-based functional rates of ColE1 RNAII and MS2 phage RNA and their mutants using our MME and MMC tools respectively. I also show that the MME and MMC tools can be applied to map-based approximations of protein energy energy landscapes and present kinetics analysis results for several proteins.

12-fold Quasicrystallography from affine E6, B6, and F4  

E-Print Network (OSTI)

Quasicrystallography may take a century to settle down as commented by Prof Freeman J. Dyson in an address to the American Mathematical Society. One possible way to obtain the quasicrystallographic structures is the projections of the higher dimensional lattices in 2D or 3D. This paper introduces a general technique for the projections of the lattices described by the affine Coxeter groups and, as examples, apply it to the projections of the lattices described by the affine Coxeter groups Wa(E6), Wa(B6), and Wa(F4) onto the Coxeter plane. These are the groups described by the Coxeter number h=12. The dihedral subgroup D12 of the Coxeter groups plays the crucial role in the symmetry of the projected set of points. It can be derived by defining two generators R1 and R2 which act as reflection generators in the orthogonal planes where the product R1R2 describes the Coxeter element of the Coxeter group. The canonical projections (strip projections) of the lattices determine the nature of the quasicrystallographic structures with 12-fold symmetry as well as the crystallographic structures with 4-fold and 6-fold symmetry. We note that the projections of the lattice Wa(F4) and Wa(B6) describe the 12-fold symmetric quasicrystal structure obtained from the Ni-Cr particles. .

Protein folding and protein metallocluster studies using synchrotron small angler X-ray scattering  

SciTech Connect

Proteins, biological macromolecules composed of amino-acid building blocks, possess unique three dimensional shapes or conformations which are intimately related to their biological function. All of the information necessary to determine this conformation is stored in a protein`s amino acid sequence. The problem of understanding the process by which nature maps protein amino-acid sequences to three-dimensional conformations is known as the protein folding problem, and is one of the central unsolved problems in biophysics today. The possible applications of a solution are broad, ranging from the elucidation of thousands of protein structures to the rational modification and design of protein-based drugs. The scattering of X-rays by matter has long been useful as a tool for the characterization of physical properties of materials, including biological samples. The high photon flux available at synchrotron X-ray sources allows for the measurement of scattering cross-sections of dilute and/or disordered samples. Such measurements do not yield the detailed geometrical information available from crystalline samples, but do allow for lower resolution studies of dynamical processes not observable in the crystalline state. The main focus of the work described here has been the study of the protein folding process using time-resolved small-angle x-ray scattering measurements. The original intention was to observe the decrease in overall size which must accompany the folding of a protein from an extended conformation to its compact native state. Although this process proved too fast for the current time-resolution of the technique, upper bounds were set on the probable compaction times of several small proteins. In addition, an interesting and unexpected process was detected, in which the folding protein passes through an intermediate state which shows a tendency to associate. This state is proposed to be a kinetic molten globule folding intermediate.

An analysis of the folding kinetics of RNase Sa showed two folding phases, indicating the presence of an intermediate and consistent with the following mechanism: D ? I ? N. Both refolding limbs of the chevron plot (abcissa = final conc. of denaturant and ordinate = kinetic rate) had non-zero slopes suggesting that proline isomerization was not rate-limiting. The conformational stability of a charge-reversed variant, WT*(D17R), of a surface exposed residue on RNase Sa has been studied by equilibrium techniques. This mutant with a single amino acid charge reversal of a surface exposed residue resulted in decreased stability. Calculations using Coulomb?s Law suggested that favorable electrostatic interactions in the denatured state were the cause for the decreased stability for the charge-reversed variant. Folding and unfolding kinetic studies were designed and conducted to study the charge-reversal effect. Unfolding kinetics showed a 10-fold increase in the unfolding rate constant for WT*(D17R) over WT* and no difference in the rate of refolding. Kinetics experiments were also conducted at pH 3 where protonation of Asp17 (charge reversal site) would be expected to negate the observed kinetic effect. At pH 3 the kinetics of unfolding of WT* RNase Sa and the WT*(D17R) mutant were more similar. These kinetic results indicate that a single-site charge reversal lowered the free energy of the denatured state as suspected. Additionally, the results showed that the transition state was stabilized as well. These results show that a specific Coulombic interaction lowered the free energy in the denatured and transition state of the charge-reversal mutant, more than in WT*. To our knowledge, this is the first demonstration that a favorable electrostatic interaction in the denatured state ensemble has been shown to influence the unfolding kinetics of a protein.

An 8-bit current mode ripple folding analog to digital converter  

E-Print Network (OSTI)

Design of an 8-bit current mode, ripple-folding analog to digital (A/D) converter is discussed. The ripple folding technique and the possible implementations in different process technologies are summarized. To have an A/D converter compatible with the standard CMOS processes, the switched current technique is used for the implementation. The architecture is a cascade of 8 minimum and maximum detectors pipelined by 7 current memories. The A/D converter, which is designed in TSMC 0.35 []m CMOS technology, achieves 8 bits of resolution at a conversion rate of 100 MHz with an SFDR of 62 dB. The total power consumption by the analog circuitry is 120mW, more than half of which is dissipated by the 8 current comparators. The achieved INL and DNL values are less than 0.4 LSB.

THE INFLUENCE OF FOLD AND FRACTURE DEVELOPMENT ON RESERVOIR BEHAVIOR OF THE LISBURNE GROUP OF NORTHERN ALASKA  

Science Conference Proceedings (OSTI)

The Carboniferous Lisburne Group is a major carbonate reservoir unit in northern Alaska. The Lisburne is detachment folded where it is exposed throughout the northeastern Brooks Range, but is relatively undeformed in areas of current production in the subsurface of the North Slope. The objectives of this study are to develop a better understanding of four major aspects of the Lisburne: (1) The geometry and kinematics of detachment folds and their truncation by thrust faults. (2) The influence of folding on fracture patterns. (3) The influence of deformation on fluid flow. (4) Lithostratigraphy and its influence on folding, faulting, fracturing, and reservoir characteristics. The Lisburne in the main axis of the Brooks Range is characteristically deformed into imbricate thrust sheets with asymmetrical hanging wall anticlines and footwall synclines. In contrast, the Lisburne in the northeastern Brooks Range is characterized by symmetrical detachment folds. The focus of our 2000 field studies was at the boundary between these structural styles in the vicinity of Porcupine Lake, in the Arctic National Wildlife Refuge. The northern edge of thrust-truncated folds in Lisburne is marked by a local range front that likely represents an eastward continuation of the central Brooks Range front. This is bounded to the north by a gently dipping panel of Lisburne with local asymmetrical folds. The leading edge of the flat panel is thrust over Permian to Cretaceous rocks in a synclinal depression. These younger rocks overlie symmetrically detachment-folded Lisburne, as is extensively exposed to the north. Six partial sections were measured in the Lisburne of the flat panel and local range front. The Lisburne here is about 700 m thick and is interpreted to consist primarily of the Wachsmuth and Alapah Limestones, with only a thin veneer of Wahoo Limestone. The Wachsmuth (200 m) is gradational between the underlying Missippian Kayak Shale and the overlying Mississippian Alapah, and increases in resistance upward. The Alapah consists of a lower resistant member (100 m) of alternating limestone and chert, a middle recessive member (100 m), and an upper resistant member (260 m) that is similar to Wahoo in the northeastern Brooks Range. The Wahoo is recessive and is thin (30 m) due either to non-deposition or erosion beneath the sub-Permian unconformity. The Lisburne of the area records two major episodes of transgression and shallowing-upward on a carbonate ramp. Thicknesses and facies vary along depositional strike. Asymmetrical folds, mostly truncated by thrust faults, were studied in and south of the local range front. Fold geometry was documented by surveys of four thrust-truncated folds and two folds not visibly cut by thrusts. A portion of the local range front was mapped to document changes in fold geometry along strike in three dimensions. The folds typically display a long, non-folded gently to moderately dipping backlimbs and steep to overturned forelimbs, commonly including parasitic anticline-syncline pairs. Thrusts commonly cut through the anticlinal forelimb or the forward synclinal hinge. These folds probably originated as detachment folds based on their mechanical stratigraphy and the transition to detachment folds to the north. Their geometry indicates that they were asymmetrical prior to thrust truncation. This asymmetry may have favored accommodation of increasing shortening by thrust breakthrough rather than continued folding. Fracture patterns were documented in the gently dipping panel of Lisburne and the asymmetrical folds within it. Four sets of steeply dipping extension fractures were identified, with strikes to the (1) N, (2) E, (3) N to NW, and (4) NE. The relative timing of these fracture sets is complex and unclear. En echelon sets of fractures are common, and display normal or strike-slip sense. Mesoscopic and penetrative structures are locally well developed, and indicate bed-parallel shear within the flat panel and strain within folds. Three sets of normal faults are well developed in the area, and are unusual

EFFICIENT PARALLEL COMPUTATION OF ALL-PAIRS N-BODY ACCELERATION BY DO-LOOP FOLDING  

SciTech Connect

The computational load inside a do loop is equalized by folding the loop appropriately if the amount of load is a linear function of the loop index. Using this idea, we develop an efficient parallel computation scheme of Newtonian all-pairs N-body acceleration vectors with help from OpenMP architecture. Using a consumer PC with a quad-core eight-thread processor, the new parallel scheme runs 4.2-4.9 times faster than a serial computation when the number of particles exceeds a few hundred.

The elasto-/hydro-dynamics of quasicrystals with 12- and 18-fold symmetries in some soft matters and mathematical solutions  

E-Print Network (OSTI)

The observation recently of 12-fold quasicrystals in polymers, nanoparticle mixture and 12-fold and 18-fold quasicrystals in colloidal solutions are important events for the study of quasicrystals. To describe the mechanical behaviour we propose a new solid-liquid phase quasicrystal model for some soft matters including polymers and colloids. The so-called new solid-liquid phase, is a new phase model of anisotropic fluid, but different from liquid crystal phase, here the structure presents quasiperiodic symmetry. Based on the model, the elasticity, fluidity and viscosity of the material have been studied, the relevant mathematical theory has also been proposed. Some mathematical solutions of the theory are discussed.

MitoNEET is a Uniquely Folded Outer Mitochondrial Membrane Protein  

NLE Websites -- All DOE Office Websites (Extended Search)

MitoNEET is a Uniquely Folded Outer MitoNEET is a Uniquely Folded Outer Mitochondrial Membrane Protein Stabilized by Diabetes Drugs The rise in obesity in the United States parallels a dramatic increase in obesity-associated diseases, most notably type-2 diabetes. This disease is predicted to reach epidemic proportions in the next several decades (Zimmet et al 2001, Urek et al 2007). Thus, understanding the biochemical processes underlying type-2 diabetes and identifying new targets for therapeutic intervention are critical for national and world health. A drug of choice to treat type-II diabetes is pioglitazone, a thiazolidinedione (TZD) derivative originally thought to exert its effect through activation of the nuclear transcription factor PPARg. Recently, a novel protein target for pioglitazone was discovered and was called mitoNEET (Colca et al 2004). This protein is anchored to the outer mitochondrial membrane (OMM) (Wiley et al 2007). Contrary to predictions that this was a zinc-finger transcription factor we discovered that mitoNEET is a novel 2Fe-2S protein.

Folding of a DNA Hairpin Loop Structure in Explicit Solvent Using Replica-Exchange Molecular Dynamics Simulations.  

DOE Green Energy (OSTI)

The research described in this product was performed in part in the Environmental Molecular Sciences Laboratory, a national scientific user facility sponsored by the Department of Energy's Office of Biological and Environmental Research and located at Pacific Northwest National Laboratory. Hairpin loop structures are common motifs in folded nucleic acids. The 59-GCGCAGC sequence in DNA forms a characteristic and stable trinucleotide hairpin loop flanked by a two basepair stem helix. To better understand the structure formation of this hairpin loop motif in atomic detail, we employed replica-exchange molecular dynamics (RexMD) simulations starting from a single-stranded DNA conformation. In two independent 36 ns RexMD simulations, conformations in very close agreement with the experimental hairpin structure were sampled as dominant conformations (lowest free energy state) during the final phase of the RexMDs (;35% at the lowest temperature replica). Simultaneous compaction and accumulation of folded structures were observed. Comparison of the GCA trinucleotides from early stages of the simulations with the folded topology indicated a variety of central loop conformations, but arrangements close to experiment that are sampled before the fully folded structure also appeared. Most of these intermediates included a stacking of the C2 and G3 bases, which was further stabilized by hydrogen bonding to the A5 base and a strongly bound water molecule bridging the C2 and A5 in the DNA minor groove. The simulations suggest a folding mechanism where these intermediates can rapidly proceed toward the fully folded hairpin and emphasize the importance of loop and stem nucleotide interactions for hairpin folding. In one simulation, a loop motif with G3 in syn conformation (dihedral flip at N-glycosidic bond) accumulated, resulting in a misfolded hairpin. Such conformations may correspond to long-lived trapped states that have been postulated to account for the folding kinetics of nucleic acid hairpins that are slower than expected for a semiflexible polymer of the same size.

In contrast, Lisburne in the main axis of the Brooks Range is deformed into imbricate thrust sheets with asymmetrical hangingwall anticlines and footwall synclines. The Continental Divide thrust front separates these different structural styles in the Lisburne and also marks the southern boundary of the northeastern Brooks Range. Field studies were conducted for this project during 1999 to 2001 in various locations in the northeastern Brooks Range and in the vicinity of Porcupine Lake, immediately south of the Continental Divide thrust front. Results are summarized below for the four main subject areas of the study.

Predicting methane accumulations generated from humic Carboniferous coals in the Donbas fold belt (Ukraine)  

Science Conference Proceedings (OSTI)

The numerical modeling of the Ukrainian part of the Donbas fold belt indicates that the coalification pattern was controlled mainly by the maximum burial depth of coal seams and the heat flow (HF) (40-75 mW/m{sup 2}) during the Permian. The coalification pattern was overprinted by magmatic events during the Late Permian in the south syncline (150 mW/m{sup 2}) and during the Permian-Triassic in the north of the Krasnoarmeisk region (120 mW/m{sup 2}). The coalification pattern shows a strong increase in vitrinite reflectance values toward the east and southeastern parts of the study area likely caused by (1) an eastward increase in burial depth, (2) a probable eastward increase in HF, and, (3) probable magmatic activity. An increase in total erosion toward the eastern and southeastern parts was also observed with a maximum erosional amount of approximately 8 km (5 mi) in the southeastern part of the study area. The basin modeling of this area predicts that the main phase of hydrocarbon generation occurred during the Carboniferous-Early Permian subsidence. The magmatic events that occurred during the Permian-Triassic caused renewed pulses of hydrocarbon generation. A large amount of the generated hydrocarbons was lost to the surface because of a lack of seals. However, the numerical simulation predicts accumulations of about 2 tcf (57 billion m{sup 3}) of methane generated from Carboniferous coals in the south and main synclines, where Lower Permian seal rocks are preserved. Finally, this study provides data on methane resources along the northern flank

Conservation of the C-type lectin fold for massive sequence variation in a Treponema diversity-generating retroelement  

Science Conference Proceedings (OSTI)

Anticipatory ligand binding through massive protein sequence variation is rare in biological systems, having been observed only in the vertebrate adaptive immune response and in a phage diversity-generating retroelement (DGR). Earlier work has demonstrated that the prototypical DGR variable protein, major tropism determinant (Mtd), meets the demands of anticipatory ligand binding by novel means through the C-type lectin (CLec) fold. However, because of the low sequence identity among DGR variable proteins, it has remained unclear whether the CLec fold is a general solution for DGRs. We have addressed this problem by determining the structure of a second DGR variable protein, TvpA, from the pathogenic oral spirochete Treponema denticola. Despite its weak sequence identity to Mtd ({approx}16%), TvpA was found to also have a CLec fold, with predicted variable residues exposed in a ligand-binding site. However, this site in TvpA was markedly more variable than the one in Mtd, reflecting the unprecedented approximate 10{sup 20} potential variability of TvpA. In addition, similarity between TvpA and Mtd with formylglycine-generating enzymes was detected. These results provide strong evidence for the conservation of the formylglycine-generating enzyme-type CLec fold among DGRs as a means of accommodating massive sequence variation.

A Summary of Information on the Behavior of the Yakima Fold Belt as a Structural Entity -- Topical Report  

SciTech Connect

This document is one in a series of topical reports compiled by the Pacific Northwest National Laboratory to summarize technical information on selected topics important to the performance of a probabilistic seismic hazard analysis (PSHA) of the Hanford Site. The purpose of this report is to summarize available data and analyses relevant to the Yakima Fold Belt (YFB) that may bear on the question of whether or not the YFB behaves as a single seismotectonic province in which activity along one fold structure is representative of behavior along all other fold structures. This topic has met with a fairly high level of contention in the expert community and has the potential to result in significant impacts on an evaluation of seismic hazard at the Hanford Site. This report defines the relevant alternative conceptual models relevant to this technical issue and the arguments and data that support those models. It provides a brief description of the technical issue and principal uncertainties; a general overview on the nature of the technical issue, along with alternative conceptual models, supporting arguments and information, and uncertainties; and finally, it suggests some possible approaches for reducing uncertainties regarding this issue.

Regional seismic reflection line, southern Illinois Basin, provides new data on Cambrian rift geometry, Hicks Dome genesis, and the Fluorspar Area Fault Complex  

SciTech Connect

Detailed studies of the subsurface structure of the Cambrian Reelfoot rift (RFR) in the Midwestern US provide important insights into continental rifting processes and into the structural fabric of a zone of modern intracratonic seismicity (New Madrid zone). High-quality oil industry seismic reflection data show that in the area of transition between the RFR and the Rough Creek Graben (RCG) the geometry of the Cambrian rift system is that of a half-graben that thickens to the southeast. This contrasts with the northward-thickening half-graben observed to the east in the RCG and with the more symmetric graben to the south in the RFR. An 82.8-km segment of a northwest-southeast seismic reflection profile in southeastern Illinois and western Kentucky shows that near Hicks Dome, Illinois, Middle and Lower Cambrian syn-rift sedimentary rocks occupy about 0.35 s (two-way travel time) on the seismic reflection section (corresponding to a thickness of about 970 m). This stratigraphic interval occupies about 0.45 s (1,250 m) near the Ohio river and is thickest against the Tabb Fault System (TFS) in Kentucky, where it occupies 0.7 s (1,940 m). The seismic data show that in this part of the Cambrian rift the master fault was part of the TFS and that normal displacement on the TFS continued through middle Paleozoic time. The seismic data also provide new information on the late Paleozoic development of Hicks-Dome and the surrounding Fluorspar Area Fault Complex (FAFC) in southeastern Illinois and western Kentucky. A series of grabens and horsts in the FAFC document a late Paleozoic reactivation of the RFR. Comparison of the reflection data with surface mineralization patterns shows that in most cases mineralized graben-bounding faults clearly cut basement or are splays from faults that cut basement.

Crystal Structures of RMI1 and RMI2, Two OB-Fold Regulatory Subunits of the BLM Complex  

Science Conference Proceedings (OSTI)

Mutations in BLM, a RecQ-like helicase, are linked to the autosomal recessive cancer-prone disorder Bloom's syndrome. BLM associates with topoisomerase (Topo) III{alpha}, RMI1, and RMI2 to form the BLM complex that is essential for genome stability. The RMI1-RMI2 heterodimer stimulates the dissolution of double Holliday junction into non-crossover recombinants mediated by BLM-Topo III{alpha} and is essential for stabilizing the BLM complex. However, the molecular basis of these functions of RMI1 and RMI2 remains unclear. Here we report the crystal structures of multiple domains of RMI1-RMI2, providing direct confirmation of the existence of three oligonucleotide/oligosaccharide binding (OB)-folds in RMI1-RMI2. Our structural and biochemical analyses revealed an unexpected insertion motif in RMI1N-OB, which is important for stimulating the dHJ dissolution. We also revealed the structural basis of the interaction between RMI1C-OB and RMI2-OB and demonstrated the functional importance of the RMI1-RMI2 interaction in genome stability maintenance.

A Novel Fold in the Tral Relaxase-Helicase C-Terminal Domain Is Essential for Conjugative DNA Transfer  

Science Conference Proceedings (OSTI)

TraI relaxase-helicase is the central catalytic component of the multiprotein relaxosome complex responsible for conjugative DNA transfer (CDT) between bacterial cells. CDT is a primary mechanism for the lateral propagation of microbial genetic material, including the spread of antibiotic resistance genes. The 2.4-{angstrom} resolution crystal structure of the C-terminal domain of the multifunctional Escherichia coli F (fertility) plasmid TraI protein is presented, and specific structural regions essential for CDT are identified. The crystal structure reveals a novel fold composed of a 28-residue N-terminal {alpha}-domain connected by a proline-rich loop to a compact {alpha}/{beta}-domain. Both the globular nature of the {alpha}/{beta}-domain and the presence as well as rigidity of the proline-rich loop are required for DNA transfer and single-stranded DNA binding.

A Summary of Coupled, Uncoupled, and Hybrid Tectonic Models for the Yakima Fold Belt--Topical Report  

SciTech Connect

This document is one in a series of topical reports compiled by the Pacific Northwest National Laboratory to summarize technical information on selected topics important to the performance of a probabilistic seismic hazard analysis of the Hanford Site. The purpose of this report is to summarize the range of opinions and supporting information expressed by the expert community regarding whether a coupled or uncoupled model, or a combination of both, best represents structures in the Yakima Fold Belt. This issue was assessed to have a high level of contention with up to moderate potential for impact on the hazard estimate. This report defines the alternative conceptual models relevant to this technical issue and the arguments and data that support those models. It provides a brief description of the technical issue and principal uncertainties; a general overview on the nature of the technical issue, along with alternative conceptual models, supporting arguments and information, and uncertainties; and finally, suggests some possible approaches for reducing uncertainties regarding this issue.

IQGAP Proteins Reveal an Atypical Phosphoinositide (aPI) Binding Domain with a Pseudo C2 Domain Fold  

SciTech Connect

Class I phosphoinositide (PI) 3-kinases act through effector proteins whose 3-PI selectivity is mediated by a limited repertoire of structurally defined, lipid recognition domains. We describe here the lipid preferences and crystal structure of a new class of PI binding modules exemplified by select IQGAPs (IQ motif containing GTPase-activating proteins) known to coordinate cellular signaling events and cytoskeletal dynamics. This module is defined by a C-terminal 105-107 amino acid region of which IQGAP1 and -2, but not IQGAP3, binds preferentially to phosphatidylinositol 3,4,5-trisphosphate (PtdInsP3). The binding affinity for PtdInsP3, together with other, secondary target-recognition characteristics, are comparable with those of the pleckstrin homology domain of cytohesin-3 (general receptor for phosphoinositides 1), an established PtdInsP3 effector protein. Importantly, the IQGAP1 C-terminal domain and the cytohesin-3 pleckstrin homology domain, each tagged with enhanced green fluorescent protein, were both re-localized from the cytosol to the cell periphery following the activation of PI 3-kinase in Swiss 3T3 fibroblasts, consistent with their common, selective recognition of endogenous 3-PI(s). The crystal structure of the C-terminal IQGAP2 PI binding module reveals unexpected topological similarity to an integral fold of C2 domains, including a putative basic binding pocket. We propose that this module integrates select IQGAP proteins with PI 3-kinase signaling and constitutes a novel, atypical phosphoinositide binding domain that may represent the first of a larger group, each perhaps structurally unique but collectively dissimilar from the known PI recognition modules.

Investigation of the reaction {sup 208}Pb({sup 18}O, f): Folding angular distributions of fission fragments and gamma-ray multiplicity  

Science Conference Proceedings (OSTI)

Correlations between folding angular distributions of fission fragments and the gamma-ray multiplicity are studied for {sup 18}O + {sup 208}Pb interactions at energies of the beam of {sup 18}O ions in the range E{sub lab} = 78-198.5 MeV. The probabilities are determined for complete-and incomplete-fusion processes inevitably followed by the fission of nuclei formed in these processes. It is found that the probability of incomplete fusion followed by fission increases with increasing energy of bombarding ions. It is shown that, for the incomplete-fusion process, folding angular distributions of fission fragments have a two-component structure. The width of folding angular distributions (FWHM) for complete fusion grows linearly with increasing energy of {sup 18}O ions. The multiplicity of gamma rays from fission fragments as a function of the linear-momentum transfer behaves differently for different energies of projectile ions. This circumstance is explained here by the distinction between the average angular momenta of participant nuclei in the fusion and fission channels, which is due to the difference in the probabilities of fission in the cases where different numbers of nucleons are captured by the target nucleus.

Simple numerical simulation for liquid dominated geothermal reservoir  

SciTech Connect

A numerical model for geothermal reservoir has been developed. The model used is based on an idealized, two-dimensional case, where the porous medium is isotropic, nonhomogeneous, filled with saturated liquid. The fluids are assumed to have constant and temperature dependent viscosity. A Boussinesq approximation and Darcy’s law are used. The model will utilize a simple hypothetical geothermal system, i.e. graben within horsts structure, with three layers of different permeabilities. Vorticity plays an importance roles in the natural convection process, and its generation and development do not depend only on the buoyancy, but also on the magnitude and direction relation between the flow velocity and the local gradient of permeability to viscosity ratio. This model is currently used together with a physical, scaled-down reservoir model to help conceptual modeling.

Geothermal investigations at Crystal Hot Springs, Salt Lake County, Utah. Report of Investigation No. 139  

DOE Green Energy (OSTI)

The Crystal Hot Springs geothermal system is located in southern Salt Lake County, Utah 22.5 km (14 miles) south of Salt Lake City near the town of Draper. The system is immediately west of the Wasatch Mountains at the easternmost edge of the Basin and Range physiographic province within an active seismic zone referred to as the Intermountain Seismic Belt. The springs are located north of an east-west trending horst known as the Traverse Range. The range is intermediate in elevation between the Wasatch Range to the east and the valley grabens to the north and south. A series of northeast striking normal faults with a combined displacement of at least 90/sup 0/m (3000 ft) separate the horst from the Jordan Valley graben to the north. The spring system is located between two closely spaced range-front faults where the faults are intersected by a north-northeast striking fault. The fractured Paleozoic quartzite bedrock 25 m (80 ft) beneath the surface leaks thermal water into the overlying unconsolidated material and the springs issue along zones of weaknesses in the relatively impermeable confining zone that parallel the bedrock faults. Meteoric water from the Wasatch Range is warmed in the normal geothermal gradient of the province (approximately 32/sup 0/C/km) as the water circulates to a minimum depth of approximately 2.5 km (1.55 miles) via an undetermined path through aquifers and faults. Data collected at the Crystal Hot Springs system under the DOE state coupled program are presented for use by individuals interested in the system.

This indicates that irradiation using an industrially practical ion beam, which generally has kinetic energy less than 5 MeV, can provide a substantial increase in the in-field current performance of high-temperature superconductor films. Transmission electron microscopy results show that point-like defects smaller than 6 nm in diameter were created in the films by the irradiation.

Folding model study of the charge-exchange scattering to the isobaric analog state and implication for the nuclear symmetry energy  

E-Print Network (OSTI)

The Fermi transition (\\Delta L=\\Delta S=0 and \\Delta T=1) between the nuclear isobaric analog states (IAS), induced by the charge-exchange (p,n) or (3He,t) reaction, can be considered as "elastic" scattering of proton or 3He by the isovector term of the optical potential (OP) that flips the projectile isospin. The accurately measured (p,n) or (3He,t) scattering cross-section to the IAS can be used, therefore, to probe the isospin dependence of the proton or 3He optical potential. Within the folding model, the isovector part of the OP is determined exclusively by the neutron-proton difference in the nuclear densities and the isospin dependence of the effective nucleon-nucleon (NN) interaction. Because the isovector coupling explicitly links the isovector part of the proton or 3He optical potential to the cross section of the charge-exchange (p,n) or (3He,t) scattering to the IAS, the isospin dependence of the effective (in-medium) NN interaction can be well tested in the folding model analysis of these charge-exchange reactions. On the other hand, the same isospin- and density dependent NN interaction can also be used in a Hartree-Fock calculation of asymmetric nuclear matter, to estimate the nuclear matter energy and its asymmetry part (the nuclear symmetry energy). As a result, the fine-tuning of the isospin dependence of the effective NN interaction against the measured (p,n) or (3He,t) cross sections should allow us to make some realistic prediction of the nuclear symmetry energy and its density dependence.

Evaluation Of Microdosing Strategies For Studies In Preclinical Drug Development: Demonstration Of Linear Pharmacokinetics In Dogs Of A Nucleoside Analogue Over A 50-Fold Dose Range  

SciTech Connect

The technique of accelerator mass spectrometry (AMS) was validated successfully and utilized to study the pharmacokinetics and disposition in dogs of a preclinical drug candidate (Compound A), after oral and intravenous administration. The primary objective of this study was to examine whether Compound A displayed linear kinetics across sub-pharmacological (microdose) and pharmacological dose ranges in an animal model, prior to initiation of a human microdose study. The AMS-derived disposition properties of Compound A were comparable to data obtained via conventional techniques such as LC-MS/MS and liquid scintillation counting analyses. Thus, Compound A displayed multiphasic kinetics and possessed low plasma clearance (4.4 mL/min/kg), a long terminal elimination half-life (19.4 hr) and high oral bioavailability (82%). Currently there are no published comparisons of the kinetics of a pharmaceutical compound at pharmacological versus sub-pharmacological doses employing microdosing strategies. The present study thus provides the first description of the pharmacokinetics of a drug candidate assessed under these two dosing regimens. The data demonstrated that the pharmacokinetic properties of Compound A were similar following dosing at 0.02 mg/kg as at 1 mg/kg, indicating that in the case of Compound A, the kinetics of absorption, distribution and elimination in the dog appear to be linear across this 50-fold dose range. Moreover, the exceptional sensitivity of AMS provided a pharmacokinetic profile of Compound A, even following a microdose, which revealed aspects of the disposition of this agent that were inaccessible by conventional techniques. The applications of accelerator mass spectrometry (AMS) are broad ranging and vary from studying environmental and ecological issues such as the isotopic composition of the atmosphere, soil and water (Hughen et al., 2000; Beck et al., 2001; Keith-Roach et al., 2001; Mironov et al., 2002), to archaeology and volcanology (Stafford et al., 1984; Vogel et al., 1990; Smith et al., 1999) to its use as a bioanalytical tool for nutritional research (Buchholz et al., 1999; Deuker et al., 2000; Weaver and Liebman, 2002). Biomedical applications of AMS and its use in the arena of pharmaceutical research also have been detailed in review articles (Barker and Garner, 1999; Garner, 2000; Turteltaub and Vogel, 2000). To date, most studies on the metabolism and disposition of xenobiotics by AMS have focused on how carcinogens bind to DNA and proteins to form adducts (Turteltaub et al., 1990, 1997; Frantz et al., 1995; Dingley et al., 1999; Li et al., 2003). Its application to the field of pharmaceutical sciences has been limited to a few studies (Kaye et al., 1997; Young et al., 2001; Garner et al., 2002). However, the pharmaceutical industry is becoming increasingly aware of the potential benefits that may accrue from the ultra high sensitivity afforded by AMS in terms of evaluating the pharmacokinetics of lead drug candidates in early development. Specifically, AMS allows administration of sub-pharmacological doses (microdoses) of carbon-14 or tritium-labeled investigational drugs to animals or humans at radiologically insignificant levels with the goal of obtaining preliminary information regarding the absorption, distribution, metabolism, and excretion of test compounds (Turteltaub and Vogel, 2000). An unresolved issue, however, is whether the pharmacokinetics determined following a microdose are representative of those following a conventional (pharmacological) dose (Lappin and Garner, 2003). This paper examines the linearity of kinetics of an antiviral nucleoside analogue, Compound A, across sub-pharmacological and pharmacological dose ranges in the dog prior to initiation of a human microdose study. The specific objectives of this study, therefore, were (1) to assess the pharmacokinetics of Compound A in dogs by a conventional dosing approach utilizing LC-MS/MS for sample analysis, (2) to assess the pharmacokinetics of Compound A in dogs by the microdose approach utilizing AMS for sample ana

UFO (UnFold Operator) user guide  

SciTech Connect

UFO is a collection of interactive utility programs for estimating unknown functions of one variable using a wide-ranging class of information as input, for miscellaneous data-analysis applications, for performing feasibility studies, and for supplementing our other software. Inverse problems, which include spectral unfolds, inverse heat-transfer problems, time-domain deconvolution, and unusual or difficult curve-fit problems, are classes of applications for which UFO is well suited. Extensive use of B-splines and (X,Y)-datasets is made to represent functions. The (X,Y)-dataset representation is unique in that it is not restricted to equally-spaced data. This feature is used, for example, in a table-generating algorithm that evaluates a function to a user-specified interpolation accuracy while minimizing the number of points stored in the corresponding dataset. UFO offers a variety of miscellaneous data-analysis options such as plotting, comparing, transforming, scaling, integrating; and adding, subtracting, multiplying, and dividing functions together. These options are often needed as intermediate steps in analyzing and solving difficult inverse problems, but they also find frequent use in other applications. Statistical options are available to calculate goodness-of-fit to measurements, specify error bands on solutions, give confidence limits on calculated quantities, and to point out the statistical consequences of operations such as smoothing. UFO is designed to do feasibility studies on a variety of engineering measurements. It is also tailored to supplement our Test Analysis and Design codes, SRAD Test-Data Archive software, and Digital Signal Analysis routines.

New Burnside Anticline: part of Fluorspar area fault complex  

SciTech Connect

Field mapping in the Abbott Formation and examination of topographic lineaments in the Creal Springs, Stonefort, Eddyville, and Harrisburg Quadrangles (southeastern Illinois) reveal the New Burnside anticline and its northeastern extension, the Stonefort anticline to be a single, extensively faulted structure. Interpretation of this evidence also leads to the conclusion that this is a fault-block structure rather than an anticline. Trending notheast-southwest, the structure seems to be the northwesternmost extent of the Fluorspar Area fault complex. The authors found evidence for two episodes of faulting. The first involved northeast-trending, high-angle faults similar to those in the known Fluorspar complex to the southeast. Faults on the northeast (Stonefort antilcine) step down toward the center of the structure, forming a graben. Vertical movement also occurred to the southwest (New Burnside anticline), but the structure in this vicinity is a horst with some blocks tilted. As with other faults in the Fluorspar complex, horizontal slickensides are present locally. The second episode of movement occurred along northwest-southeast-trending strike-slip faults that offset the northeast-trending high-angle faults. This second phase of faulting may correspond with previously reported reactivation of northwest-trending faults elsewhere in the Fluorspar Area fault complex.

Geothermal hydrology of Warner Valley, Oregon: a reconnaissance study  

DOE Green Energy (OSTI)

Warner Valley and its southern extension, Coleman Valley, are two of several high-desert valleys in the Basin and Range province of south-central Oregon that contain thermal waters. At least 20 thermal springs, defined as having temperatures of 20/sup 0/C or more, issue from Tertiary basaltic flows and tuffs in and near the valleys. Many shallow wells also produce thermal waters. The highest measured temperature is 127/sup 0/C, reported from a well known as Crump geyser, at a depth of 200 meters. The hottest spring, located near Crump geyser, has a surface temperature of 78/sup 0/C. The occurrence of these thermal waters is closely related to faults and fault intersections in the graben and horst structure of the valleys. Chemical analyses show that the thermal waters are of two types: sodium chloride and sodium bicarbonate waters. Chemical indicators show that the geothermal system is a hot-water rather than a vapor-dominated system. Conductive heat flow in areas of the valley unaffected by hydrothermal convection is probably about 75 milliwatts per square meter. The normal thermal gradient in valley-fill dpeosits in these areas may be about 40/sup 0/C per kilometer. Geothermometers and mixing models indicate that temperatures of equilibration are at least 170/sup 0/C for the thermal components of the hotter waters. The size and location of geothermal reservoirs are unknown.

Preliminary survey of tuff distribution in Esmeralda, Nye, and Lincoln Counties, Nevada  

Science Conference Proceedings (OSTI)

This report inventories the surface distribution of silicic tuffs in Nye, Esmeralda, and Lincoln Counties, NV, based on a review of available literature. The inventory was taken to provide a data base in evaluating tuff sites for the disposal of high-level nuclear waste. Silicic ash-flow tuffs that are about 11 to 34 million years (my) old are widespread in these counties. These rocks are locally deformed by right-lateral movement along Walker Lane and the Las Vegas Shear Zone, and left-lateral movement along a zone from near the Nevada Test Site (NTS) to the Utah border, and are commonly offset by steeply dipping normal faults. The normal faults that bound horsts, grabens, and tilted-fault blocks of the Basin-and-Range Province began to form 30 my ago; some are still active. Tuff distribution is discussed on a regional basis. Tuff thicknesses and alterations, structural complexity, and proximity to recent faulting, recent volcanism, and mineral resources are discussed for each area. Although the literature on which it is based is often incomplete and sketchy, this report is intended to serve as a basis for future, more detailed work that includes initial field inspection, detailed field and laboratory studies, and extrapolations to the subsurface.

The known geologic data of the San Luis Basin are reviewed and related to an understanding of the hydrogeothermal potential of the Alamosa-Monte Vista area. The physiographic setting of the region, the structural framework of the basin, and its influence on the stratigraphic makeup of the rock sequence, which in turn control the occurrence of potential deep water reservoirs, are reviewed. It is suggested that the San Luis Basin was well-developed by Miocene time, and that although the basin was modified by Neogene faulting, it is essentially a late Laramide event having been produced during the Paleogene. Attention is also given to high heat flow along the Rio Grande Rift and to the geothermal gradient of the San Luis Basin. The confined aquifer is then considered in respect to its hydrogeology, water quality, and as to the legal aspects of the system. (LEW)

Recent drilling activities at the earth power resources Tuscarora geothermal power project's hot sulphur springs lease area.  

DOE Green Energy (OSTI)

Earth Power Resources, Inc. recently completed a combined rotary/core hole to a depth of 3,813 feet at it's Hot Sulphur Springs Tuscarora Geothermal Power Project Lease Area located 70-miles north of Elko, Nevada. Previous geothermal exploration data were combined with geologic mapping and newly acquired seismic-reflection data to identify a northerly tending horst-graben structure approximately 2,000 feet wide by at least 6,000 feet long with up to 1,700 feet of vertical offset. The well (HSS-2) was successfully drilled through a shallow thick sequence of altered Tertiary Volcanic where previous exploration wells had severe hole-caving problems. The ''tight-hole'' drilling problems were reduced using drilling fluids consisting of Polymer-based mud mixed with 2% Potassium Chloride (KCl) to reduce Smectite-type clay swelling problems. Core from the 330 F fractured geothermal reservoir system at depths of 2,950 feet indicated 30% Smectite type clays existed in a fault-gouge zone where total loss of circulation occurred during coring. Smectite-type clays are not typically expected at temperatures above 300 F. The fracture zone at 2,950 feet exhibited a skin-damage during injection testing suggesting that the drilling fluids may have caused clay swelling and subsequent geothermal reservoir formation damage. The recent well drilling experiences indicate that drilling problems in the shallow clays at Hot Sulphur Springs can be reduced. In addition, average penetration rates through the caprock system can be on the order of 25 to 35 feet per hour. This information has greatly reduced the original estimated well costs that were based on previous exploration drilling efforts. Successful production formation drilling will depend on finding drilling fluids that will not cause formation damage in the Smectite-rich fractured geothermal reservoir system. Information obtained at Hot Sulphur Springs may apply to other geothermal systems developed in volcanic settings.

Prudhoe Bay western peripheral development using three-dimensional seismic  

Science Conference Proceedings (OSTI)

The western periphery of the Prudhoe Bay field, known as the West End or Eileen area, is characterized by a relatively gentle southwestern regional dip cut by numerous normal faults with up to 500 ft of throw. These faults displace the Permian-Triassic reservoir sandstones against Jurassic shales. A detailed structural map was interpreted from three-dimensional seismic data acquired in 1984 and 1985. Three distinct and coherent trends of faulting are evident from the data: north-south, northwest-southeast, and east-west. These faults were aliased by the earlier two-dimensional data grid and could not be connected in a coherent manner consistent with suppositions of the stress directions. The added detail to the structural maps will allow development of narrow, oil-filled horst blocks and should prevent drilling of dry holes in narrow grabens as has occurred prior to the three-dimensional data acquisition. Seventy-two 80-ac wells and up to four horizontal gas injectors are planned for the area, with drilling commencing from new surface facilities in 1988. Upon the successful completion of a horizontal and an 88/sup 0/ highangle well from existing facilities, the utility and shortcomings of the data interpretations were illuminated. The high-angle well encountered only 40% of the prognosed oil column, which is believed to be a consequence of an unpredicted permafrost thickening. Thus, as with two-dimensional data, the uncertainty in the estimate of the velocity field is the dominant factor in estimating subsurface structure.

Folding Proteins at 500 ns/hour with Work Queue  

E-Print Network (OSTI)

Abstract—Molecular modeling is a field that traditionally has large computational costs. Until recently, most simulation techniques relied on long trajectories, which inherently have poor scalability. A new class of methods is proposed that requires only a large number of short calculations, and for which minimal communication between computer nodes is required. We considered one of the more accurate variants called Accelerated Weighted Ensemble Dynamics (AWE) and for which distributed computing can be made efficient. We implemented AWE using the Work Queue framework for task management and applied it to an all atom protein model (Fip35 WW domain). We can run with excellent scalability by simultaneously utilizing heterogeneous resources from multiple computing platforms such as clouds (Amazon EC2, Microsoft Azure), dedicated clusters, grids, on multiple architectures (CPU/GPU, 32/64bit), and in a dynamic environment in which processes are regularly added or removed from the pool. This has allowed us to achieve an aggregate sampling rate of over 500 ns/hour. As a comparison, a single process typically achieves 0.1 ns/hour. I.

UFO (UnFold Operator) default data format  

SciTech Connect

The default format for the storage of x,y data for use with the UFO code is described. The format assumes that the data stored in a file is a matrix of values; two columns of this matrix are selected to define a function of the form y = f(x). This format is specifically designed to allow for easy importation of data obtained from other sources, or easy entry of data using a text editor, with a minimum of reformatting. This format is flexible and extensible through the use of inline directives stored in the optional header of the file. A special extension of the format implements encoded data which significantly reduces the storage required as compared wth the unencoded form. UFO supports several extensions to the file specification that implement execute-time operations, such as, transformation of the x and/or y values, selection of specific columns of the matrix for association with the x and y values, input of data directly from other formats (e.g., DAMP and PFF), and a simple type of library-structured file format. Several examples of the use of the format are given.

Hydrocarbons in New Guinea, controlled by basement fabric, Mesozoic extension and Tertiary convergent margin tectonics  

Science Conference Proceedings (OSTI)

Most models for the tectonic evolution of New Guinea involve Early and Late Miocene arc-continent collisions, creating an orogenic belt. Structural trends and prospectivity are then analyzed in terms of belts across the country; the Fold Belt (with the discovered oil and gas fields), the Mobile Belt and the accreted arcs. This model inhibits realistic assessment of prospectivity. It now appears the Mobile Belt formed by Oligocene compression then by Early Miocene extension, related to slab-rollback, that unroofed metamorphic core complexes adjacent to starved half-grabens. The grabens filled in the Middle Miocene and were largely transported intact during the Pliocene arc-collision. Early Miocene reefs and hypothesized starved basin source rocks create a viable play throughout northern New Guinea as in the Salawati Basin. The Pliocene clastic section is locally prospective due to overthrusting and deep burial. Within the Fold Belt, the site and types of oil and gas fields are largely controlled by the basement architecture. This controlled the transfer zones and depocentres during Mesozoic extension and the location of major basement uplifts during compression. In PNG, the Bosavi lineament separates an oil province from a gas province. In Irian Jaya the transition from a relatively competent sequence to a rifted sequence west of [approx]139[degrees]E may also be a gas-oil province boundary. Understanding, in detail, the compartmentalization of inverted blocks and areas of thin-skinned thrusting, controlled by the basement architecture, will help constrain hydrocarbon prospectivity.

Geologic evolution and aspects of the petroleum geology of the northern East China Sea shelf basin  

Science Conference Proceedings (OSTI)

Analysis of multichannel seismic reflection profiles reveals that the northern East China Sea shelf basin experienced two phases of rifting, followed by regional subsidence. The initial rifting in the Late Cretaceous created a series of grabens and half grabens, filled by alluvial and fluviolacustrine deposits. Regional uplift and folding (Yuquan movement) in the late Eocene-early Oligocene terminated the initial rifting. Rifting resumed in the early Oligocene, while alluvial and fluviolacustrine deposition continued to prevail. A second phase of uplift in the early Miocene terminated the rifting, marking the transition to the postrift phase. The early postrift phase (early Miocene-late Miocene) is characterized by regional subsidence and westward and northwestward marine transgression. Inversion (Longjing movement) in the late Miocene interrupted the postrift subsidence, resulting in an extensive thrust-fold belt in the eastern part of the area. The entire area entered a stage of regional subsidence again and has become a broad continental shelf. Source rocks include synrift lacustrine facies, fluvial shales, and coal beds. Synrift fluvial, lacustrine, and deltaic deposits, postrift littoral and/or shallow-marine sandstones, and fractured basement have the potential to provide reservoirs. Various types of hydrocarbon traps (e.g., faulted anticlines, overthrusts, rollover anticlines, faults, unconformity traps, combination structural-stratigraphic traps, weathered basement, and stratigraphic traps) are recognized, but many of these traps have not been tested.

DNA folding: structural and mechanical properties of the two-angle model for chromatin  

E-Print Network (OSTI)

We present a theoretical analysis of the structural and mechanical properties of the 30-nm chromatin fiber. Our study is based on the two-angle model introduced by Woodcock et al. (Woodcock, C. L., S. A. Grigoryev, R. A. Horowitz, and N. Whitaker. 1993. PNAS 90:9021-9025) that describes the chromatin fiber geometry in terms of the entry-exit angle of the nucleosomal DNA and the rotational setting of the neighboring nucleosomes with respect to each other. We explore analytically the different structures that arise from this building principle, and demonstrate that the geometry with the highest density is close to the one found in native chromatin fibers under physiological conditions. On the basis of this model we calculate mechanical properties of the fiber under stretching. We obtain expressions for the stress-strain characteristics which show good agreement with the results of recent stretching experiments (Cui, Y., and C. Bustamante. 2000. PNAS 97:127-132) and computer simulations (Katritch, V., C. Bustamante, and W. K. Olson. 2000. J. Mol. Biol. 295:29-40), and which provide simple physical insights into correlations between the structural and elastic properties of chromatin.

Mesozoic tectonic inversion in the Neuquen Basin of west-central Argentina  

E-Print Network (OSTI)

Mesozoic tectonic inversion in the Neuquen Basin of west-central Argentina produced two main fault systems: (1) deep faults that affected basement and syn-rift strata where preexisting faults were selectively reactivated during inversion based on their length and (2) shallow faults that affected post-rift and syn-inversion strata. Normal faults formed at high angle to the reactivated half-graben bounding fault as a result of hangingwall expansion and internal deformation as it accommodated to the shape of the curved footwall during oblique inversion. Contraction during inversion was initially accommodated by folding and internal deformation of syn-rift sedimentary wedges, followed by displacement along half-graben bounding faults. We suspect that late during inversion the weight of the overburden inhibited additional fault displacement and folding became the shortening-accommodating mechanism. A Middle Jurassic inversion event produced synchronous uplift of inversion structures across the central Neuquen Basin. Later inversion events (during Late Jurassic, Early Cretaceous, and Late Cretaceous time) produced an "inversion front" that advanced north of the Huincul Arch. Synchroneity of fault reactivation during the Callovian inversion event may be related to efficient stress transmission north of the Huincul Arch, probably due to easy reactivation of low-dip listric fault segments. This required little strain accumulation along "proximal" inversion structures before shortening was transferred to more distal structures. Later inversion events found harderto- reactivate fault segments, resulting in proximal structures undergoing significant inversion before transferring shortening. The time between the end of rifting and the different inversion events may have affected inversion. Lithosphere was probably thermally weakened at the onset of the initial Callovian inversion phase, allowing stress transmission over a large distance from the Huincul Arch and causing synchronous inversion across the basin. Later inversion affected a colder and more viscous lithosphere. Significant strain needed to accumulate along proximal inversion structures before shortening was transferred to more distal parts of the basin. Timing of inversion events along the central Neuquen Basin suggest a megaregional control by right-lateral displacement motion along the Gastre Fault Zone, an intracontinental megashear zone thought to have been active prior to and during the opening of the South Atlantic Ocean.

Results of a detailed gravity survey in the Alamosa Area, Alamosa County, Colorado  

DOE Green Energy (OSTI)

A total of 322 stations, centered on the City of Alamosa, were surveyed with a gravimeter during September 1981. These data have shown the Alamosa horst to have an irregular top. This irregularity is thought to be caused by paleovalleys and/or down-dropped fault blocks within the Precambrian horst. The City of Alamosa lies directly over a local gravity low. Volcanic rocks within this low may contain a reservoir for geothermal fluids, as yet unsubstantiated by drilling. Thermal fluids are thought to enter the Alamosa area via aquifers from the west (San Juan Mountains) and/or from the Rio Grande Rift zone with the fluids rising along fractures within and bordering the horst. The most favorable drilling targets appear to be either near the center of the local gravity low or in the fracture zone at the edges of the inferred down-dropped fault blocks.

Gravity and subsurface investigation of the Presidio Bolson area, Texas  

DOE Green Energy (OSTI)

An integrated geophysical-geologic study of the Presidio Bolson area was undertaken primarily using gravity measurements and deep drilling data. Over 2000 gravity readings were used to construct maps of the area and two-dimensional computer modeling of gravity profiles was used to derive earth models. These data outlined the major geologic features of the area and were dominated by Tertiary block faulting and volcanism. The main feature of interest was the Presidio Bolson, which is located in a major graben (Presidio Graben) over 1 km deep in the area near Ruidosa, Texas. These data also suggest that hot springs associated with the Presidio Graben derive their heat from buried Tertiary intrusions associated with this graben or by deep circulation along the boundary faults of the graben.

The sedimentological and geotechnical characteristics of the lower continental slope and rise of the Mississippi Fan fold belt  

E-Print Network (OSTI)

The study is based on geological and geotechnical laboratory testing data of 70 three inch diameter piston cores. Concentration is along the Sigsbee Escarpment in a grid area between 90? and 91?W and 26.7? and 27.3?N. Water depth ranges from 1,200 meters below sea level to 2,500 meters below sea level. All data were used to characterize the seafloor processes that deposited these sediments. The Sigsbee Escarpment represents a complex topographic and geologic feature involving faults, slumps and steep slopes. Most of the study area is covered by hemipelagic Holocene sediments in 0.05 to 2.9 m thickness, greatest thickness being in bathymetric lows indicating that Holocene sediments are eroded at the bathymetric highs and transported down the slope. The underlying Pleistocene sediments are mostly laminated clays in the southwestern part of the study area, indicating no mass wasting. Hemipelagic sedimentation in quiet sea bottom environment was dominant throughout the accumulation of the unit. Several generations of slumps have occurred in the northeastern part of the Sigsbee Escarpment during the Pleistocene showing that this part of the study area is an area where active mass wasting and down slope processes dominate.

Challenge for Mesozoic hydrocarbon exploration in the Eastern Indonesia  

Science Conference Proceedings (OSTI)

The eastern part of Indonesia covers approximately 3 million square kilometers, 35 percent being landmass and 65 percent covered by ocean. Only three of 38 sedimentary basins are producing hydrocarbon (Salawati, Bintuni, and Seram Basins). Oil and gas have discovered in the Lariang, Bone, Timor, Banggai, Sula and Biak Basins, however the discoveries have not developed yet. Hydrocarbon systems in Northern Australia and Papua New Guinea give the major contributions to the geological idea of Pre-Tertiary section in the less explored area in the Eastern Indonesia. The Triassic-Middle Jurassic marine carbonaceous shale sequences are the main hydrocarbon source rock in the Irian Jaya and surrounding area (Buton, gula and Seram basins). The main Mesozoic reservoir are the Kembelangan Formation in the Bintuni Basin of Irian Jaya and Bobong Formation in the North Sula Region. Exploration play types in the Eastern Indonesia can be divided into five types: 1 - Peri Cratonic, 2 - Marginal Rift Graben, 3 - Thrust Fold Belt Island Arc, 4 - Early Collision and 5 -Microcontinental Block - Advanced Collision. Recent discoveries through Mesozoic section in Eastern Indonesia are: Roabiba-1 (1990) in Bintuni Basin-Irian Jaya (Kambelangan Formation); Loku- 1 (1990) in North Sula region (Pre-Tertiary sediments); Oseil-1 (1993/94) in Bula-Seram Basin (Jurassic Manusela Formation); Elang-1 (1 994); Kakaktua-1 (1994) and Laminaria-1 in North Bonaparte Basin (Upper Jurassic Sands).

Hydrocarbon implications of Karoo Supergroup turbidites and tectonics in northern Zimbabwe  

Science Conference Proceedings (OSTI)

Field research in the relatively unstudied Lower Zambezi trough of northernmost Zimbabwe and adjacent Zambia and Mozambique has revealed a sedimentary tectonic history unlike other Karoo basin (Late Carboniferous to Early Jurassic) of the region. This presents a much better setting for petroleum deposits than has been found in those other areas. Aerial photo interpretation and reconnaissance geophysical data show strike-slip folds and faults at the surface and subbasins up to 10 km deep. This contrast with other Karoo basins, which are of a half-graben genesis, is further evident in the sedimentary sequences of the Lower Zambezi basin complex. Lacustrine turbidites occur in the Lower Karoo Kondo Pools Formation. Upper fan facies of a restricted active margin subaqueous fan system are found in limited outcrops in an accommodation zone uplift between the two subbasins. The overlying units are classical Karoo alluvial layers, but intercalated with a higher frequency of unconformities. Syndepositional and postdepositional deformation includes thrust faulting and detachment. Hydrocarbon potential is enhanced by three virtues that are lacking in other parts of southern Africa. Distal facies to those seen in exposures of the Kondo Pools Formation subaqueous fans should be rich in sapropelic mudstone, the source rock so elusive elsewhere. Second, basin depth is sufficient for thermal maturity. Finally, the tectonic regime was conducive to the formation of convex as well as unconformity traps. Mobil Oil is in the midst of an exploration program that may capitalize on these factors.

Crystal structures of MW1337R and lin2004: Representatives of a novel protein family that adopt a four-helical bundle fold  

DOE Green Energy (OSTI)

To extend the structural coverage of proteins with unknown functions, we targeted a novel protein family (Pfam accession number PF08807, DUF1798) for which we proposed and determined the structures of two representative members. The MW1337R gene of Staphylococcus aureus subsp. aureus Rosenbach (Wood 46) encodes a protein with a molecular weight of 13.8 kDa (residues 1-116) and a calculated isoelectric point of 5.15. The lin2004 gene of the nonspore-forming bacterium Listeria innocua Clip11262 encodes a protein with a molecular weight of 14.6 kDa (residues 1-121) and a calculated isoelectric point of 5.45. MW1337R and lin2004, as well as their homologs, which, so far, have been found only in Bacillus, Staphylococcus, Listeria, and related genera (Geobacillus, Exiguobacterium, and Oceanobacillus), have unknown functions and are annotated as hypothetical proteins. The genomic contexts of MW1337R and lin2004 are similar and conserved in related species. In prokaryotic genomes, most often, functionally interacting proteins are coded by genes, which are colocated in conserved operons. Proteins from the same operon as MW1337R and lin2004 either have unknown functions (i.e., belong to DUF1273, Pfam accession number PF06908) or are similar to ypsB from Bacillus subtilis. The function of ypsB is unclear, although it has a strong similarity to the N-terminal region of DivIVA, which was characterized as a bifunctional protein with distinct roles during vegetative growth and sporulation. In addition, members of the DUF1273 family display distant sequence similarity with the DprA/Smf protein, which acts downstream of the DNA uptake machinery, possibly in conjunction with RecA. The RecA activities in Bacillus subtilis are modulated by RecU Holliday-junction resolvase. In all analyzed cases, the gene coding for RecU is in the vicinity of MW1337R, lin2004, or their orthologs, but on a different operon located in the complementary DNA strand. Here, we report the crystal structures of MW1337R and lin2004, which were determined using the semiautomated, high-throughput pipeline of the Joint Center for Structural Genomics (JCSG), part of the National Institute of General Medical Sciences Protein Structure Initiative.

Assessment of Geothermal Resource Potential at a High-Priority Area on the Utah Testing and Training Range–South (UTTR–S)  

DOE Green Energy (OSTI)

Field investigations conducted during 2011 support and expand the conclusion of the original Preliminary Report that discovery of a viable geothermal system is possible in the northwestern part of the Utah Testing and Training Range-South (UTTR-S), referred to henceforth as Focus Area 1. The investigations defined the southward extent of the Wendover graben into and near Focus Area 1, enhanced the understanding of subsurface conditions, and focused further geothermal exploration efforts towards the northwestern-most part of Focus Area 1. Specifically, the detailed gravity survey shows that the Wendover graben, first defined by Cook et al. (1964) for areas north of Interstate Highway 80, extends and deepens southwest-ward to the northwest corner of Focus Area 1. At its deepest point, the intersection with a northwest-trending graben there is favorable for enhanced permeability associated with intersecting faults. Processing and modeling of the gravity data collected during 2011 provide a good understanding of graben depth and distribution of faults bounding the graben and has focused the interest area of the study. Down-hole logging of temperatures in wells made available near the Intrepid, Inc., evaporation ponds, just north of Focus Area 1, provide a good understanding of the variability of thermal gradients in that area and corroborate the more extensive temperature data reported by Turk (1973) for the depth range of 300-500 m. Moderate temperature gradients in the northern part of the Intrepid area increase to much higher gradients and bottom-hole temperatures southeastward, towards graben-bounding faults, suggesting upwelling geothermal waters along those faults. Water sampling, analysis, and temperature measurements of Blue Lakes and Mosquito Willey's springs, on the western boundary of Focus Area 1, also show elevated temperatures along the graben-bounding fault system. In addition, water chemistry suggests origin of those waters in limestone rocks beneath the graben in areas with temperatures as high as 140 C (284 F). In conclusion, all of the field data collected during 2011 and documented in the Appendices of this report indicate that there is reasonable potential for a viable geothermal resource along faults that bound the Wendover graben. Prospects for a system capable of binary electrical generation are especially good, and the possibility of a flash steam system is also within reason. The next steps should focus on securing the necessary funding for detailed geophysical surveys and for drilling a set of temperature gradient wells to further evaluate the resource, and to focus deep exploration efforts in the most promising areas.

Structural style of the Turkana Rift, Kenya  

SciTech Connect

Multifold seismic reflection and geologic mapping in part of the eastern branch of the East African Rift system of northern Kenya reveal a major rift structure containing at least 3 km of Neogene sediment fill beneath Lake Turkana. This includes a series of half-graben basins, with centrally located quaternary volcanic centers, which are linked end-to-end by structural accommodation zones. Whereas the geometry of rifting is similar to that of the nonvolcanic western branch of the East African Rift system, the Turkana half-grabens are much smaller and may reflect extension of a thinner lithosphere or development of more closely spaced fracture patterns during rift evolution, or both.

Geology and Thermal Regime of Bert Winn #1 geothermal Test, Franklin County, Idaho  

DOE Green Energy (OSTI)

The conclusions of this report are: (1) Bert Winn No.1 did not encounter high-temperature zones of permeability, except possibly at 5,575 to 5,700 feet, where chloride conductivity indicates saline fluid entry, and where stabilized temperature may be 210-215 F. (2) Structurally, Bert Winn No.1 appears to have penetrated into the horst footwall block, penetrating progressively away from the horst-bounding faults believed to leak hot fluids. (3) Projections based on disequilibrium temperatures taken at 24 and 36 hours suggest a stabilized maximum temperature of about 260-265 F at 7,450. Maximum observed temperature was 243 F. (4) Geochemically, temperatures at depth should be over 300 F. On the basis of observed temperatures and gradients, 400 F might not be encountered until 12,000 feet at this site. (5) C.H. Stocks 1-A, about one mile northwest, appears to be hotter at comparable depths, and to be better located to penetrate the range-front fault set at drillable depth. (6) Bert Winn No.1 was sited principally on a geoelectrical anomaly in an area of high temperature gradients. With the remote exception of the saline interval at 5,575 to 5,700 feet, no evidence was seen in drilling and logging of any feature that could serve as the source of the geoelectrical anomaly.

BACA Project: geothermal demonstration power plant. Final report  

DOE Green Energy (OSTI)

The various activities that have been conducted by Union in the Redondo Creek area while attempting to develop the resource for a 50 MW power plant are described. The results of the geologic work, drilling activities and reservoir studies are summarized. In addition, sections discussing the historical costs for Union's involvement with the project, production engineering (for anticipated surface equipment), and environmental work are included. Nineteen geothermal wells have been drilled in the Redondo Creek area of the Valles Caldera: a prominent geologic feature of the Jemez mountains consisting of Pliocene and Pleistocene age volcanics. The Redondo Creek area is within a complex longitudinal graben on the northwest flank of the resurgent structural dome of Redondo Peak and Redondo Border. The major graben faults, with associated fracturing, are geologically plausible candidates for permeable and productive zones in the reservoir. The distribution of such permeable zones is too erratic and the locations too imprecisely known to offer an attractive drilling target. Log analysis indicates there is a preferred mean fracture strike of N31W in the upper portion of Redondo Creek wells. This is approximately perpendicular to the major structure in the area, the northeast-striking Redondo Creek graben. The geothermal fluid found in the Redondo Creek reservoir is relatively benign with low brine concentrations and moderate H/sub 2/S concentrations. Geothermometer calculations indicate that the reservoir temperature generally lies between 500/sup 0/F and 600/sup 0/F, with near wellbore flashing occurring during the majority of the wells' production.

REACTIVE MULTIPHASE BEHAVIOR OF CO2 IN SALINE AQUIFERS BENEATH THE COLORADO PLATEAU  

Science Conference Proceedings (OSTI)

Soil CO{sub 2} flux surveys have been conducted over known CO{sub 2} reservoirs at Farnham Dome, Utah, Crystal Geyser-Ten Mile Graben in Utah and Springerville-St. Johns, Arizona. No anomalous CO{sub 2} flux was detected at the Farnham Dome and Springerville-St. Johns. At Crystal Geyser-Ten Mile Graben, localized areas of anomalously high CO{sub 2} flux ({approx}100 g m{sup -2} day{sup -1}) occur along a fault zone near visibly degassing features. Isotopic measurements on CO{sub 2} collected from nearby springs indicate that it originated at depth. Evidence of widespread vein calcite at the surface (Farnham Dome) and travertine deposits at the other two areas suggests that discharge of CO{sub 2}-rich fluids has occurred in the past. Despite the lack of evidence for significant present day leakage of CO{sub 2} to the atmosphere at Springerville-St. Johns and Crystal Geyser-Ten Mile Graben, there are significant outflows of high-bicarbonate water in both areas suggesting continuous migration of CO{sub 2} in the aqueous phase from depth. The very localized nature of the CO{sub 2} flux anomalies, and the outflow of ground water containing dissolved CO{sub 2} present challenges for effective, long term monitoring of CO{sub 2} leakage.

Session 10: The Cerro Prieto Geothermal Field, Mexico: The Experiences Gained from Its Exploration and Development  

DOE Green Energy (OSTI)

The Cerro Prieto case study demonstrated the value of a multidisciplinary effort for exploring and developing a geothermal field. There was no problem in recognizing the geothermal potential of the Cerro Prieto area because of the many obvious surface manifestations. However, the delineation of the geothermal reservoir at depth was not so straightforward. Wells drilled near the abundant surface manifestations only produced fluids of relatively low enthalpy. Later it was determined that these zones of high heat loss corresponded to discharge areas where faults and fractures allowed thermal fluids to leak to the surface, and not to the main geothermal reservoir. The early gravity and seismic refraction surveys provided important information on the general structure of the area. Unaware of the existence of a higher density zone of hydrothermally altered sediments capping the geothermal reservoir, CFE interpreted a basement horst in the western part of the field and hypothesized that the bounding faults were controlling the upward flow of thermal fluids. Attempting to penetrate the sedimentary column to reach the ''basement horst'', CFE discovered the {alpha} geothermal reservoir (in well M-5). The continuation of the geothermal aquifer (actually the {beta} reservoir) east of the original well field was later confirmed by a deep exploration well (M-53). The experience of Cerro Prieto showed the importance of chemical ratios, and geothermometers in general, in establishing the subsurface temperatures and fluid flow patterns. Fluid chemical and isotopic compositions have also been helpful to determine the origin of the fluids, fluid-production mechanisms and production induced effects on the reservoir.

BACA Project: geothermal demonstration power plant. Final report  

SciTech Connect

The various activities that have been conducted by Union in the Redondo Creek area while attempting to develop the resource for a 50 MW power plant are described. The results of the geologic work, drilling activities and reservoir studies are summarized. In addition, sections discussing the historical costs for Union's involvement with the project, production engineering (for anticipated surface equipment), and environmental work are included. Nineteen geothermal wells have been drilled in the Redondo Creek area of the Valles Caldera: a prominent geologic feature of the Jemez mountains consisting of Pliocene and Pleistocene age volcanics. The Redondo Creek area is within a complex longitudinal graben on the northwest flank of the resurgent structural dome of Redondo Peak and Redondo Border. The major graben faults, with associated fracturing, are geologically plausible candidates for permeable and productive zones in the reservoir. The distribution of such permeable zones is too erratic and the locations too imprecisely known to offer an attractive drilling target. Log analysis indicates there is a preferred mean fracture strike of N31W in the upper portion of Redondo Creek wells. This is approximately perpendicular to the major structure in the area, the northeast-striking Redondo Creek graben. The geothermal fluid found in the Redondo Creek reservoir is relatively benign with low brine concentrations and moderate H/sub 2/S concentrations. Geothermometer calculations indicate that the reservoir temperature generally lies between 500/sup 0/F and 600/sup 0/F, with near wellbore flashing occurring during the majority of the wells' production.

Reflection seismic profiling in Wabash Valley fault system in southwestern Indiana  

SciTech Connect

During the summer of 1988 common-depth-point (CDP) reflection seismic profiling was initiated by ARPEX in southwestern Indiana in the Wabash Valley fault system. A 2.2-im (1.4-mi) east-west profile was shot across the Mt. Vernon graben in Posey County. Minihole shooting in 21-m (68.9-ft) patterns using 3.4 kg (7.5 lb) of seismic explosives distributed in five 3-m (10-ft) holes provided the energy source. Most shotholes were made with a reversible air-driven penetrating tool that was effective in dense clays. The 12-geophone array length was 43 m (141 ft), and the nominal far-trace offset was 2.1 km (7,000 ft). A 48-channel recording yielded 24-CDP coverage at 11-m (36-ft) intervals. Data were enhanced by gapped deconvolution, bandpass filtering, and CDP stack. The strongest and most continuous reflections at 0.75 and 1.6 sec are associated with the New Albany Shale (Devonian-Mississippian) and Eau Claire Formation (Cambrian), respectively. Within the Mt. Vernon graben and east of the Spenser Consolidated oil field, the depth to Eau Claire Formation apparently increases by approximately 60 m (197 ft) over a horizontal distance of 1.4 km (0.9 mi). Minor faulting east of the Spencer Consolidated field appears to be synthetic to the Hovey lake fault, which bounds the eastern side of the Mt. Vernon graben. Tentative interpretations of faulting and weak reflections from depths greater than 4.5 km (15,000 ft) may be clarified by additional data processing and by additional seismic profiling planned by ARPEX.

Sediment infill within rift basins: Facies distribution and effects of deformation: Examples from the Kenya and Tanganyika Rifts, East Africa  

SciTech Connect

Oil is known from lacustrine basins of the east African rift. The geology of such basins is complex and different depending on location in the eastern and western branches. The western branch has little volcanism, leading to long-lived basins, such as Lake Tanganyika, whereas a large quantity of volcanics results in the eastern branch characterized by ephemeral basins, as the Baringo-Bogoria basin in Kenya. The Baringo-Bogoria basin is a north-south half graben formed in the middle Pleistocene and presently occupied by the hypersaline Lake Bogoria and the freshwater Lake Baringo. Lake Bogoria is fed by hot springs and ephemeral streams controlled by grid faults bounding the basin to the west. The sedimentary fill is formed by cycles of organic oozes having a good petroleum potential and evaporites. On the other hand, and as a consequence of the grid faults, Lake Baringo is fed by permanent streams bringing into the basin large quantities of terrigenous sediments. Lake Tanganyika is a meromictic lake 1470 m deep and 700 km long, of middle Miocene age. It is subdivided into seven asymmetric half grabens separated by transverse ridges. The sedimentary fill is thick and formed by organic oozes having a very good petroleum potential. In contrast to Bogoria, the lateral distribution of organic matter is characterized by considerable heterogeneity due to the existence of structural blocks or to redepositional processes.

REACTIVE MULTIPHASE BEHAVIOR OF CO2 IN SALINE AQUIFERS BENEATH THE COLORADO PLATEAU  

DOE Green Energy (OSTI)

Field and laboratory investigations of naturally occurring CO{sub 2}-reservoirs are being conducted to determine the characteristics of potential seal and reservoir units and the extent of the interactions that occur between the host rocks and the CO{sub 2} charged fluids. Efforts have focused on the Farnham Dome field, located in central Utah, the Springerville-St. Johns field in Arizona and New Mexico, and most recently, the Crystal Geyser-Salt Wash graben areas with their CO{sub 2}-charged geysers and springs in central Utah. At both the Springerville-St. Johns field and the central Utah CO{sub 2} spring area, there is evidence of extensive travertine deposits that document release of CO{sub 2} to the atmosphere. At Farnham Dome, calcite debris fields appear to be remnants of vein calcite and an earlier period of fluid leakage. The main achievements during this quarter are (1): preparation for a soil gas flux survey in October at the Crystal Geyser --Little Grand Wash fault zone, and the Salt Wash graben; (2) submission of an abstract to the upcoming Measurement, Monitoring and Verification session at the Fall AGU meeting; (3) submission of an invited abstract to the Gordon Conference on Hydrocarbon Resources; and (4) receipt of initial radiocarbon dates of travertine from the Springerville-St Johns field. Analytical results and interpretations of both the travertine deposition and the soil gas surveys are still in progress, and will be included in future quarterly reports.

Alba field - middle Eocene deep-water channel in U. K. North Sea  

SciTech Connect

The Alba field is located in the Witch Ground graben between the Fladen Ground spur to the north and the Renee Ridge to the south, entirely in UKCS Block 16/26. In 1985, oil was discovered in the middle Eocene sands of the Horda formation at a depth of 6100 ft subsea. Twelve additional wells, including sidetracks, have been drilled appraise the discovery. This drilling indicates the Alba field is a stratigraphic trap covering an area of 3600 ac. The Alba sands represent a brief interruption in the hemipelagic sedimentation that dominated this part of the Witch Ground graben during the middle Eocene. Sediment was supplied intermittently from a shelf area to the northwest into a deep-water environment. Well correlations, seismic facies analysis, and core analysis indicate that these sands were deposited as part of a constructional channel/levee complex within a mud-rich, shelf-sourced submarine fan system. The cap and the updip and lateral seals to the reservoir are shale. The Alba reservoir is predominantly a homogeneous, fine-grained, unconsolidated sand. The average reservoir porosity is 33% and the average permeability is 2.8 darcys. Oil in place is estimated to be 1.1 billion bbl of 20/degrees/ API crude.

Structure of the Presidio Bolson area, Texas, interpreted from gravity data  

DOE Green Energy (OSTI)

To obtain a better understanding of the structure and tectonism of the region, an integrated geophysical-geological study of the Presidio area, Texas, was undertaken using gravity measurements and deep drilling data. New gravity data were combined with existing data to construct simple Bouguer anomaly maps of the Presidio area, and two-dimensional computer modeling of gravity profiles was used to derive earth models. These data outline the major geologic features of the area that are dominated by the effects of Tertiary block faulting and volcanism. The main feature of interest was the Presidio Graben, which is approximately 1.5 km deep near Ruidosa, Texas. One motivation for this study was the collection of a part of the basic scientific data needed to assess the geothermal potential of the area, and the results obtained support the hypothesis that hot springs associated with the Presidio Graben derive their heat from deep circulation along its boundary faults. However, some gravity anomalies observed could be interpreted as indicating the presence of late Tertiary intrusions that could provide heat for the hot springs.

Solid-sample geochemistry study of western Dixie Valley, Churchill County, Nevada. Part II. Soil geochemistry  

Science Conference Proceedings (OSTI)

Numerous thermal springs present in northern Dixie Valley, Nevada, are the surface expression of a deep-seated geothermal system. The structural setting, a complex asymmetric graben controls the location of surface springs and migration of thermal fluids to the surface. The distribution of arsenic and mercury in the soils of the valley correlates well with the occurrence of structures which may be in communication with the underlying geothermal system. Generally anomalous arsenic values occur along structures near the playa where fine-grained sediments and a high water table occur. Mercury values are uniformly low near the playa but are typically anomalous along structures in the coarser fan deposits. The complementary geochemical signatures of arsenic and mercury which arise from basic differences in elemental chemical behavior have been useful in delineating the structural trends of the valley. The structural model indicated by the geochemistry and results of drilling suggest future targets should be selected east of the Dixie Meadows fault, within the inner graben.

Geophysical Evidence for the Availability of Geothermal Energy in New Britian  

DOE Green Energy (OSTI)

This paper combines some of the results and interpretations of geological mapping, seismic refraction, marine seismic, and gravity surveys to show that large tracts of New Britain could be favorable targets for geothermal power development. It is shown that the fractured and faulted lithosphere is associated with grabens and rifts in which mantle material has risen to within 10 to 15 km from the surface. The grabens and rifts are marked by volcanism in which the dominant volcanic rocks are olivine--and tholeiitic--basalts, with a sprinkling of more acid volcanics ranging from dacite to andesite. Following A. Rittman the basalts are believed to have originated in the asthenosphere when the lithosphere was broken up under a tensional stress regime; the acid volcanics were formed by magmatic differentiation within the crust. it was argued that ideal geothermal reservoirs are capped with altered ash deposits or other nonpermeable volcanics. To feed such reservoirs conduits are required which are naturally located on fault or shear zones. The two areas selected as favorable for future geothermal power development are located between Talasea and Lolobau Is., say around Hoskins; and near Rabaul, between Matupi Harbor and Matupi. As a type area, the rift between the Gazelle Peninsula and New Ireland resembles the Afar triangle, at the northern end of the Great Valley Rift system of Africa.

REACTIVE MULTIPHASE BEHAVIOR OF CO{sub 2} IN SALINE AQUIFERS BENEATH THE COLORADO PLATEAU  

DOE Green Energy (OSTI)

Soil gas surveys have been carried out on the Colorado Plateau over areas with natural occurrences of CO{sub 2}. At Farnham Dome, Utah, and Springerville-St. Johns, Arizona, proven CO{sub 2} reservoirs occur at 600-800 m depth, but no anomalous soil gas CO{sub 2} flux was detected. Background CO{sub 2} fluxes of up to about 5 g m{sup -2} day{sup -1} were common in arid, poorly vegetated areas, and fluxes up to about 20 g m{sup -2} day{sup -1} were found at Springerville-St. Johns in heavily vegetated, wet ground adjacent to springs. These elevated fluxes are attributed to shallow root zone activity rather than to a deep upflow of CO{sub 2}. Localized areas of anomalously high CO{sub 2} gas flux ({approx} 100 g m{sup -2} day{sup -1}) were documented along the Little Grand Wash Fault Zone near Crystal Geyser, Utah and nearby in Ten Mile Graben, but those in Ten Mile Graben are not directly associated with the major faults. In both areas, features with a visible gas flux are present. Isotopic measurements on the CO{sub 2} gas confirm that it originated at depth. Evidence of widespread vein calcite at the surface at Farnham Dome and travertine deposits in the other areas suggests that there has been an outflow of CO{sub 2}-rich fluids in the past. 14C ages of pollen trapped in the travertine at Springerville-St. Johns record a period of CO{sub 2} leakage to the atmosphere between 887 {+-} 35 and 3219 {+-} 30 years BP. No travertine deposits appear to be currently forming. At Springerville-St. Johns, Crystal Geyser and Ten Mile Graben, there are significant outflows of high-bicarbonate water. Movement of CO{sub 2}-rich groundwaters may be the dominant mechanism controlling the mobility of CO{sub 2} today. The very localized nature of the soil gas anomalies, evidence of large scale discharge of CO{sub 2} over a very short period of time and the outflow of ground water containing dissolved CO{sub 2} will present challenges for effective, long term monitoring of CO{sub 2} leakage.

Preliminary assessment of the geothermal resource potential of the Yuma area, Arizona  

DOE Green Energy (OSTI)

The Yuma area has had a long and complex tectonic history. The most southwesterly corner of the area presently comprises a small segment of the Salton Trough, a deep sediment-filled structural depression. Known geothermal anomalies in the Salton Trough make the Yuma area a favorable exploration target even though spreading-center heat sources are not expected to occur there. Geological and geophysical investigations reveal that the area is made up of low, rugged northwest-trending mountains separated by deep sediment-filled basins. Relief is a result of both erosional and structural activity. Northwest-trending en-echelon faults bound the range fronts and the basins, and have created several horst blocks (basement highs) that crop out at or near the surface. The Algodonnes fault is inferred to represent the northeast margin of the Salton Trough and apparently an inactive extension of the San Andreas fault system. Extensive well-pumping and applications of irrigation waters in recent years have created an unnatural state of flux in the hydrologic regime in the Yuma area. Gravity and aeromagnetic anomalies trend strongly northwest through the region as do lineaments derived from Landsat and Skylab photos. Electrical resistivity values in the Bouse Formation are exceptionally low, about 3 ohn-m. Heat flow appears to be normal for the Basin and Range province. Ground-water temperatures indicate zones of rising warm water, with one such warm anomaly confirmed by sparse geothermal-gradient data.

This system is currently being developed for geothermal energy production. The hot springs are in a region of complex and intersecting fault trends associated with two major extensional events, the Oregon-Idaho Graben and the Western Snake River Plain. The intersection of these two fault systems, coupled with high geothermal gradients from thin continental crust produces pathways for surface water and deep geothermal water interactions at Neal Hot Springs.

Geothermal energy resource assessment of parts of Alaska. Final report  

DOE Green Energy (OSTI)

The central Seward Peninsula was the subject of a geological, geophysical and geochemical reconnaissance survey during a 30-day period in the summer of 1980. The survey was designed to investigate the geothermal energy resource potential of this region of Alaska. A continental rift system model was proposed to explain many of the Late Tertiary-to-Quaternary topographic, structural, volcanic and geothermal features of the region. Geologic evidence for the model includes normal faults, extensive fields of young alkalic basalts, alignment of volcanic vents, graben valleys and other features consistent with a rift system active from late Miocene time to the present. Five traverses crossing segments of the proposed rift system were run to look for evidence of structure and geothermal resources not evident from surface manifestation. Gravity, helium and mercury soil concentrations were measured along the traverses. Seismic, resistivity, and VLF studies are presented.

Mountain home known geothermal resource area: an environmental analysis  

DOE Green Energy (OSTI)

The Mountain Home KGRA encompasses an area of 3853 hectares (ha) at the foot of the Mount Bennett Hills in Elmore County, Idaho. The site is associated with an arid climate and high winds that generate an acute dust problem. The KGRA lies adjacent to the northwest-southeast trending fault zone that reflects the northern boundary of the western Snake River Plain graben. Data indicate that a careful analysis of the subsidence potential is needed prior to extensive geothermal development. Surface water resources are confined to several small creeks. Lands are utilized for irrigated farmlands and rangeland for livestock. There are no apparent soil limitations to geothermal development. Sage grouse and mule deer are the major species of concern. The potential of locating significant heritage resources other than the Oregon Trail or the bathhouse debris appears to be relatively slight.

Thermal regimes of major volcanic centers: magnetotelluric constraints  

DOE Green Energy (OSTI)

The focus of activity at this laboratory is on applying natural electromagnetic methods along with other geophysical techniques to studying the dynamical processes and thermal regimes associated with centers of major volcanic activity. We are presently emphasizing studies of the Long Valley/Mono Craters Volcanic Complex, the Cascades Volcanic Belt, and the Valles Caldera. This work addresses questions regarding geothermal energy, chemical transport of minerals in the crust, emplacement of economic ore deposits, and optimal siting of drill-holes for scientific purposes. In addition, since much of our work is performed in the intermontane sedimentary basins of the western US (along with testing our field-system in some of the graben structures in the Northeast), there is an application of these studies to developing exploration and interpretational strategies for detecting and delineating structures associated with hydrocarbon reserves.

Deep resistivity structure in southwestern Utah and its geothermal significance  

DOE Green Energy (OSTI)

Magnetotelluric (MT) measurements in southwestern Utah have yielded a model of resistivity structure in this area to a depth of about 100 km. The MT observations are strongly affected by Great Basin graben sedimentary fill, which constitutes conductive upper-crustal lateral inhomogeneity and requires simulation using two- and three-dimensional modeling algorithms before deeper portions of the resistivity section can be resolved. Included in the model is a layer of low resistivity (20 ..cap omega..-m) residing from 35 to 65 km depth. Sensitivity tests of the data to the structure weigh strongly against the top of this layer being as shallow as 25 km and against the conductivity and thickness of the layer being highly correlated. No intra-crustal low-resistivity layer is indicated by the MT data.

Solid-sample geochemistry study of western Dixie Valley, Churchill County, Nevada. Part I. Petrochemistry  

Science Conference Proceedings (OSTI)

Numerous thermal springs present in northern Dixie Valley, Nevada, are the surface expression of a deep-seated geothermal system. The structural setting, a complex asymmetric graben possibly bifurcating to the north, controls the location of surface springs and migration of thermal fluids to the surface. A large-scale surface soil geochemical survey for mercury and arsenic and petrochemical analysis for selected trace elements in subsurface samples from two deep exploratory wells allowed for identification of steam and hot water entries and delineation of associated geochemical zonations. Data thus far indicate the Dixie Valley geothermal system is dynamic, with temperatures greater than 200/sup 0/C at depths of 2500 m to 3000 m and access to thermal fluids controlled by structural and temporal parameters.

Integrated exploration for low-temperature geothermal resources in the Honey Lake basin, California  

Science Conference Proceedings (OSTI)

An integrated exploration study is presented to locate low-temperature geothermal reservoirs in the Honey Lake area of northern California. Regional studies to locate the geothermal resources included gravity, infrared, water-temperature, and water-quality analyses. Five anomalies were mapped from resistivity surveys. Additional study of three anomalies by temperature-gradient and seismic methods was undertaken to define structure and potential of the geothermal resource. The gravity data show a graben structure in the area. Seismic reflection data, indicate faults associated with surface-resistivity and temperature-gradient data. The data support the interpretation that the shallow reservoirs are replenished along the fault zones by deeply circulating heated meteoric waters.

Sweet Lake Geopressured-geothermal Project, Magma Gulf-Technadril/DOE Amoco Fee. Volume II. Surface installations reservoir testing. Annual report, February 28, 1981-February 10, 1982  

DOE Green Energy (OSTI)

The Magma Gulf-Technadril/Department of Energy Amoco Fee No. 1 (production) and salt water disposal wells were drilled in the period from August, 1980 to February 1981. Surface facilities were designed and constructed during March-June 1981. Flow testing began in June 1981 and continued until February, 1982. The Miogypsinoides interval contains seven discrete sands in the test well. These sands have been numbered 1 to 7, beginning at the top of the sequence. Data from wireline logs and core samples suggested that the first zone to be perforated should be Sand 5. Because of its high porosity and permeability, Sand 5 was thought to contain almost 50% of the total hydraulic capacity of the well. Flow testing of Sand 5 was performed in three stages, each of which is fully described in this report. Phase I was designed as an initial clean-up flow and a reservoir confirmation test. Phase II consisted of the reservoir limit determination test and lasted 17 days. Boundaries were confirmed which suggest that the Sweet Lake reservoir is fairly narrow, with boundaries on three sides, but is open in one direction with no closure for at least 4-1/4 miles. These boundaries approximate the shape of the graben in which the test well was drilled, but may or may not be directly related to the major faults forming the graben. Phase III testing was planned to be a long-term test at commercial design rates. Although Sand 5 alone would not support such rates, long-term production was demonstrated. Additional research not supported by DOE funding was also performed during the period covered by this report. This research, consisting of mud logging, micropaleontology, organic geochemistry, core analysis, and rock mechanics, is summarized in this report.

Permian evolution of sandstone composition in a complex back-arc extensional to foreland basin: The Bowen Basin, eastern Australia  

SciTech Connect

The Bowen Basin is a Permo-Triassic, back-arc extensional to foreland basin that developed landward of an intermittently active continental volcanic arc associated with the eastern Australian convergent plate margin. The basin has a complex, polyphase tectonic history that began with limited back-arc crustal extension during the Early Permian. This created a series of north-trending grabens and half grabens which, in the west, accommodated quartz-rich sediment derived locally from surrounding, uplifted continental basement. In the east, coeval calc-alkaline, volcanolithic-rich, and volcaniclastic sediment was derived from the active volcanic arc. This early extensional episode was followed by a phase of passive thermal subsidence accompanied by episodic compression during the late Early Permian to early Late Permian, with little contemporaneous volcanism. In the west, quartzose sediment was shed from stable, polymictic, continental basement immediately to the west and south of the basin, whereas volcanolithic-rich sediment that entered the eastern side of the basin during this time was presumably derived from the inactive, and possibly partly submerged volcanic arc. During the late Late Permian, flexural loading and increased compression occurred along the eastern margin of the Bowen Basin, and renewed volcanism took place in the arc system to the east. Reactivation of this arc led to westward and southward spread of volcanolithic-rich sediment over the entire basin. Accordingly, areas in the west that were earlier receiving quartzose, craton-derived sediment from the west and south were overwhelmed by volcanolithic-rich, arc-derived sediment from the east and north. This transition from quartz-rich, craton-derived sediments to volcanolithic-rich, arc-derived sediments is consistent with the interpreted back-arc extensional to foreland basin origin for the Bowen Basin.

Tectonic framework of Crater Flat basin, adjacent to Yucca Mountain, Nevada: A preliminary report  

SciTech Connect

Detailed mapping of 9.5--14 Ma volcanic rocks in Crater Flat (CF) and vicinity is being used to test alternative tectonic models which form a basis for seismic risk assessments for a potential nuclear waste repository at Yucca Mountain. Preliminary results are: (1) the southern margin of the basin is a NW-trending right-oblique-slip fault; (2) two down-to-the-east normal faults form the western boundary of the basin against 2 different structural domains, a little-extended uplift called Bare Mountain to the south, and the much-extended Fluorspar Hills (FH) to the north. These two domains are separated by the roughly E-trending, left-oblique-slip Fluorspar Canyon fault; (3) Crater Flat basin actually is separated from the Fluorspar Hills by a narrow septum, the Tram Ridge horst (TR), which was a localized site of nondeposition from 11.5--13.1 Ma, and which experienced only minor extension during the peak periods of extension, at 12 and < 11 Ma, in Crater Flat and the Fluorspar Hills, respectively; (4) normal faults within Crater Flat are radial to, and largely decrease in throw northward toward the Timber Mountain caldera complex, which appears to have acted as a pivot point during opening of the basin; (5) increased faulting and tilting of strata with age reflects intermittent tectonism in Crater Flat throughout the volcanic period. The data also suggest a change in least principal stress direction from NNW before 13.1 Ma to WNW after. In combination, these results indicate that Crater Flat basin formed by simultaneous E-W extension and NW-directed right-lateral shear; it could be described as a half-rhombochasm. To date, the authors find no support for a model that explains the basin as a buried caldera. Future mapping is planned to test the differing predictions of strike-slip (Walker Lane) and detachment-fault models.

Application of heat-flow techniques to geothermal energy exploration, Leach Hot Springs area, Grass Valley, Nevada  

DOE Green Energy (OSTI)

A total of 82 holes ranging in depth from 18 to 400 meters were drilled for thermal and hydrologic studies in a 200 km/sup 2/ area of Grass Valley, Nevada, near Leach Hot Springs. Outside the immediate area of Leach Hot Springs, heat flow ranges from 1 to 6.5 hfu with a mean of 2.4 hfu (1 hfu = 10/sup -6/ cal cm/sup 2/ s/sup -1/ = 41.8 mWm/sup -2/). Within 2 km of the springs, conductive heat flow ranges between 1.6 and more than 70 hfu averaging 13.6 hfu. Besides the conspicuous thermal anomaly associated with the hot springs, two additional anomalies were identified. One is associated with faults bounding the western margin of the Tobin Range near Panther Canyon, and the other is near the middle of Grass Valley about 5 km SSW of Leach Hot Springs. The mid-valley anomaly appears to be caused by hydrothermal circulation in a bedrock horst beneath about 375 meters of impermeable valley sediments. If the convective and conductive heat discharge within 2 km of the Leach Hot Springs is averaged over the entire hydrologic system (including areas of recharge), the combined heat flux from this part of Grass Valley is about 3 hfu, consistent with the average regional conductive heat flow in the Battle Mountain High. The hydrothermal system can be interpreted as being in a stationary stable phase sustained by high regional heat flow, and no localized crustal heat sources (other than hydrothermal convection to depths of a few kilometers) need be invoked to explain the existence of Leach Hot Springs.

Miocene structure of Mustang Island, Mustang Island East Addition and part of Matagorda Island, Outer Continental Shelf areas, Gulf of Mexico  

E-Print Network (OSTI)

Understanding the Miocene structure of Mustang Island and the neighboring areas in the northwestern Gulf of Mexico helps to increase knowledge of the geology and hence contribute to petroleum exploration and production in the area. Interpretation of about 1465 miles of multifold, migrated seismic reflection data, integrated with 35 well log data, served to detail the Miocene structure and its evolution. Early Miocene sedimentation resulted in differential loading of mobile substrates of shale. This caused movement of the shale basinward. Further loading caused overlying sediments to yield, forming the Clemente-Tomas fault. This is a listric, down to the basin growth fault, lying on the seaward flanks of a shale ridge. Rollover anticlines characterize the hangingwall blocks of this fault especially in the southwestern part of the study area. These rollover anticlines could be potential hydrocarbon traps. Rapid sedimentation during the Middle Miocene was responsible for the formation of the contemporaneous growth faults of the Corsair-Wanda system. The Corsair fault is an extensive, listric, mostly concave up growth fault that diagonally runs through the area along a southwest-northeast trend. A salt withdrawal syncline separates the Wanda from the Corsair fault. This suggests that the Corsair formed as a result of primary salt withdrawal. Planar rotation of hangingwall blocks of the Corsair fault formed structural highs that are able to accumulate hydrocarbons. Continued sedimentation during the Middle-Upper Miocene caused the underlying salt to undergo secondary withdrawal. This withdrawal caused the overlying sediments to collapse into a half-turtle anticline upon which the Wanda fault appears to detach. The half-turtle anticlines and a series of horsts could be prospective zones of hydrocarbon accumulation. The Wanda fault zone appears to lie along the landward limit of salt deposition in this part of the Gulf of Mexico. The only salt diapir in the area lies immediately basinward of the Wanda fault.

Magnetotelluric investigations at the Roosevelt Hot Springs KGRA and Mineral Mountains, Utah. Topical report 78-1701. a. 6. 1  

DOE Green Energy (OSTI)

Twenty-five magnetotelluric (MT) sites were monitored. Amongst other MT functions, the transverse electric (TE) and transverse magnetic (TM) apparent resistivity and impedance phase data were provided for the frequency range 3 x 10/sup -3/ Hz to 100 Hz. Some one-dimensional inversion results for this area yielded very low values of estimated true resistivity. Such values are unrealistic in light of established notions about conductivity mechanisms in earth materials. Furthermore, the assembly of such inversions to form a crude two-dimensional model has yielded a calculated 2-D pseudosection far removed from the observed pseudosection. Trial-and-error modeling has provided a better fit although strong differences between observed and modeled data remain and cannot be overcome by any purely two-dimensional model. The most noteworthy difficulty is the presence of exaggerated contrasts in apparent resistivity persisting to the lowest frequency of observation for both modes of wave excitation. Single-conductor, 2-D, TE and TM modeling may explain such problems in terms of three-dimensional effects. Electrical strike estimation may be a meaningless endeavour in a strongly three-dimensional area. The total fields do not decompose into the standard principal modes (TE and TM) and H/sub z/ depends on horizontal derivatives of both electric field components. Multiple symmetry axes result in multiple estimated strike directions depending upon wherethe observer is located. When derivatives of electric field are relatively small, noise may be the determining factor. The estimated strike directions for the Roosevelt stations are, however, quite consistent. The elongate resistive horst structure of the Mineral Mts. situated in conductive valley fill is felt to be the overwhelming reason for such a consistency.

Evolutionary sequences and hydrocarbon potential of Kenya sedimentary basins  

Science Conference Proceedings (OSTI)

Kenya basins have evolved primarily through extension related to episodic continental rifting. In eastern Kenya, thick accumulations of sediments formed within grabens during the prerift phase (Precambrian to Carboniferous) of the Gondwana breakup. Synrift sedimentation (Late Carboniferous to Middle Jurassic) occurred within a north-south rift system, which included the Mandera basin, South Anza basin, and Lamu embayment. During the Early Jurassic, a marine transgression invaded the margins of the eastern Kenya rift basins, resulting in the deposition of platform carbonates and shales. A Callovian-aged salt basin formed in the offshore regions of the Lamu embayment. Intermittent tectonic activity and eustatic sea-level changes controlled sedimentation, which produced marine shales, carbonates or evaporites, and fluvio-deltaic to lacustrine sandstones. From the Early Cretaceous to recent, continental sediments were deposited within the North Anza and Turkana basins. These fluvial-lacustrine sediments are similar to the Lower Cretaceous sequences that have produced oil in the Mesozoic Sudanese Abu Gabra rift. Although exploration activities began in the early 1950s, significant occurrences of potential reservoir, source, and seal lithologies as well as trapping configurations remain in many areas. Favorable structures and sequences of reservoir sandstones and carbonates overlain by potentially sealing lacustrine or marine shales, evaporites, or volcanics have been noted. Potential source beds are believed to be present within shales of the lacustrine or marine depositional environments.

Hydrocarbon potential of the Lamu basin of south-east Kenya  

SciTech Connect

The Lamu basin occupies the coastal onshore and offshore areas of south-east Kenya. This fault bounded basin formed as a result of the Paleozoic-early Mesozoic phase of rifting that developed at the onset of Gondwana dismemberment. The resultant graben was filled by Karroo (Permian-Early Jurassic) continental siliciclastic sediments. Carbonate deposits associated with the Tethyan sea invasion, dominate the Middle to Late Jurassic basin fill. Cessation of the relative motion between Madagascar and Africa in the Early Cretaceous, heralded passive margin development and deltaic sediment progradation until the Paleogene. Shallow seas transgressed the basin in the Miocene when another carbonate regime prevailed. The basin depositional history is characterized by pulses of transgressive and regressive cycles, bounded by tectonically enhanced unconformities dividing the total sedimentary succession into discrete megasequences. Source rock strata occur within Megasequence III (Paleogene) depositional cycle and were lowered into the oil window in Miocene time, when the coastal parts of the basin experienced the greatest amount of subsidence. The tectono-eustatic pulses of the Tertiary brought about source and reservoir strata into a spatial relationship in which hydrocarbons could be entrapped. A basement high on the continental shelf has potential for Karroo sandstone and Jurassic limestone reservoirs. Halokinesis of Middle Jurassic salt in Miocene time provides additional prospects in the offshore area. Paleogene deltaic sands occur in rotated listric fault blacks. A Miocene reef Play coincides with an Eocene source rock kitchen.

Exploration of volcanic geothermal energy resources based on rheological techniques. Final report  

DOE Green Energy (OSTI)

Tidal strain and tilt field observations were carried out during the period February 1978 to December 1979 at the Klamath Graben and Newberry Caldera in Oregon and at Krafla in Northern Iceland. Moreover, tilt observations were made at Mt. St. Helens, Washington, during the summer of 1980. Two strainmeters of the same type as now in use by the US Geological Survey were applied in the strain work. Tilts were measured by two Kinemetrics model TM-1B biaxial tilt meters. The instruments were placed at depths of approximately one to two meters below the ground surface. Both strain and tilt fields turn out to be heavily contaminated by noise that is mostly of thermoelastic origin. In spite of considerable efforts, it has not been possible to process the strain field data to obtain sufficiently clear tidal signals. The tilt data are less contaminated and rather clear tidal signals were observed at Newberry in Oregon and Krafla in Iceland. A local magnification by a factor of about 3 of the EW component of the theoretical solid earth and ocean load tilt was observed at one station at Krafla. Moreover, the tidal tilt component across the ring fault at Newberry appears to be magnified by a factor of 1.4 to 1.9. The phenomena at the Krafla may possibly be due to a local magma chamber. These results are a clear indication of a tilt field modification by local structure and indicate the possibility of using tilt data to locate subsurface magma bodies.

Sweet lake geopressured-geothermal project, Magma Gulf-Technadril/DOE Amoco Fee. Annual report, December 1, 1979-February 27, 1981. Volume I. Drilling and completion test well and disposal well  

DOE Green Energy (OSTI)

The Sweet lake site is located approximately 15 miles southeast of Lake Charles in Cameron Parish, Louisiana. A geological study showed that the major structure in this area is a graben. The dip of the beds is northwesterly into the basin. A well drilled into the deep basin would find the target sand below 18,000', at high pressures and temperatures. However, since there is no well control in the basin, the specific site was chosen on the 15,000' contour of the target sand in the eastern, more narrow part of the garben. Those key control wells are present within one mile of the test well. The information acquired by drilling the test well confirmed the earlier geologic study. The target sand was reached at 15,065', had a porosity of over 20% and a permeability to water of 300 md. The original reservoir pressure was 12,060 psi and the bottom hole temperature 299{sup 0}F. There are approximately 250 net feet of sand available for the perforation. The disposal well was drilled to a total depth of 7440'.

Acord 1-26 hot, dry well, Roosevelt Hot Springs hot dry rock prospect, Utah  

DOE Green Energy (OSTI)

The Acord 1-26 well is a hot, dry well peripheral to the Roosevelt Hot Springs known geothermal resource area (KGRA) in southwestern Utah. The bottom-hole temperature in this 3854-m-deep well is 230/sup 0/C, and the thermal gradient is 54/sup 0/C/km. The basal 685 m, comprised of biotite monzonite and quartz schist and gneiss, is a likely hot, dry rock (HDR) prospect. The hole was drilled in a structural low within the Milford Valley graben and is separated from the Roosevelt KGRA to the east by the Opal Mound Fault and other basin faults. An interpretation of seismic data approximates the subsurface structure around the well using the lithology in the Acord 1-26 well. The hole was drilled with a minimum of difficulty, and casing was set to 2411 m. From drilling and geophysical logs, it is deduced that the subsurface blocks of crystalline rock in the vicinity of the Acord 1-26 well are tight, dry, shallow, impermeable, and very hot. A hydraulic fracture test of the crystalline rocks below 3170 m is recommended. Various downhole tools and techniques could be tested in promising HDR regimes within the Acord 1-26 well.

Apacheta, a new geothermal prospect in Northern Chile  

DOE Green Energy (OSTI)

The discovery of two high-temperature fumaroles, with gas geochemistry compatible with an economic geothermal system, established Apacheta as one of the most attractive geothermal exploration prospects in northern Chile. These remote fumaroles at 5,150 m elevation were first sampled in 1999 by ENAP and its partners, following up on the reports of a CODELCO water exploration well that flowed small amounts of dry steam at 4,540 m elevation in the valley 4.5 km east of the fumaroles. The prospect is associated with a Plio-Pleistocene volcanic complex located within a NW-trending graben along the axis of the high Andes. The regional water table is 4,200 masl. There are no hot springs, just the 88 degrees C steam well and the 109 degrees and 118 degrees C fumaroles with gas compositions that indicate reservoir temperatures of greater than or equal to 250 degrees C, using a variety of gas geothermometers. An MT-TDEM survey was completed in 2001-2002 by Geotermica del Norte (SDN), an ENAP-C ODELCO partnership, to explore the Apacheta geothermal concession. The survey results indicated that base of the low resistivity clay cap has a structural apex just west of the fumaroles, a pattern typically associated with shallow permeability within a high temperature geothermal resource. SGN plans to drill at least one exploration well in 2002-03 to characterize a possible economic resource at Apacheta.

Analysis of Cameron Parish geopressured aquifer. Final report  

DOE Green Energy (OSTI)

The Sweet Lake geopressured-geothermal prospect is located in northern Cameron Parish, Louisiana in T.12 S., R. 7 W. and T. 12 S., R. 8 W. approximately 10 to 15 miles south of Lake Charles. The region is characterized by Cenozoic sand and clay deposits of geosynclinal thickness and differentially uplifted salt structures. The primary geopressured-geothermal aquifer is the Miogyp sand of the Camerina zone (Upper Frio formation of Oligocene-Miocene age). The main prospect is located in a basin on the north flank of the Hackberry-Big Lake-Sweet Lake salt ridge. Interpretation of 27 miles of seismic lines and 17 deep well logs localizes the prospect in a basin with northwesterly dip in a graben between east--west faults converging eastward. Aquifer depth ranges from 14,000 to 18,000 feet. Net sand thickness exceeds 400 feet with 22% porosity. Temperatures range from 280/sup 0/F. (corrected) at 14,000 feet to 350/sup 0/F. at 18,000 feet. Geopressures occur below 9,000 feet with mud weight equivalents in the sand from 12 to 13 pounds per gallon. Net sand volume of one cubic mile is estimated in the area mapped.

Three-dimensional seismic imaging of the Rye Patch geothermal reservoir  

DOE Green Energy (OSTI)

A 3-D surface seismic survey was conducted to explore the structure of the Rye Patch geothermal reservoir (Nevada), to determine if modern seismic techniques could be successfully applied in geothermal environments. Furthermore, it was intended to map the structural features which may control geothermal production in the reservoir. The seismic survey covered an area of 3.03 square miles and was designed with 12 north-south receiver lines and 25 east-west source lines. The receiver group interval was 100 feet and the receiver line spacing was 800 feet. The source interval was 100 feet while the source line spacing was 400 feet. The sources were comprised of 4 vibrator trucks arranged in a box array. Seismic processing involved, among other steps, the picking of over 700,000 of the possible one million traces to determine first arrival travel times, normal moveout correction, 3-D stack, deconvolution, time migration, and depth conversion. The final data set represents a 3-D cube of the subsurface structure in the reservoir. Additionally, the travel times were used to perform tomographic inversions for velocity estimates to support the findings of the surface seismic imaging. The results suggest the presence of at least one dominant fault responsible for the migration of fluids in the reservoir. Furthermore, it is suggested that this feature might be part of a fault system that includes a graben structure.

Samples from seven outcrop and subsurface localities situated in the northeast (northern Luangwa Valley), east (mid-Luangwa Valley), south (mid-Zambezi Valley), and the Western Province of Zambia were studied. The coal measures are from 9 to 280 m thick, but individual coal seams are generally less than 6 m. The coal macerals contain an average of 60% vitrinite and 9% liptinite, enough to have potential to generate hydrocarbon. A few samples contain twice this amount of liptinite. Reflected-light microscopy and the thermal alteration index of spores were used to determine the thermal maturity. The organic matter in samples studied is within the oil generation zone (thermal alteration index 2{minus} to 2+; %R{sub 0} max = 0.5-0.9). The petrological and palynological data indicate that the organic matter consists of Types II (generally approximately 25% in carbonaceous shale samples), III, and IV, indicating source rock potential. Late Karoo ( ) and post-Karoo fault blocks with differential vertical displacements may have produced structural traps suitable for oil and gas accumulation.

The basins on the Argentine continental margin  

Science Conference Proceedings (OSTI)

After the stabilization of the central Gondwana Craton, orogenic belts were accreted, as a result of convergence events and an extensive passive margin developed in southwestern Gondwana. Thermal subsidence in Parana, Karoo-Ventania basins and the Late Paleozoic-Early Mesozoic rifts, were modified by the Gondwana breakup and the South Atlantic opening. Early Paleozoic marine transgressions deposited the Table Mountain Group in Ventania. In southwestern Patagonia foreland clastics were deposited. Magmatic arcs and marine units indicate a tectonic trough was formed, alternating with continental sequences, over Late Paleozoic metamorphics and intrusives, resulting from plastered terrains along the Gondwana margin. In Patagonia, Permo-Carboniferous continental and glacio marine clastics infill the basins, while in Ventania, paralic sequences, grade from neritic to continental to the northeast, extending beneath the continental margin. The Triassic-Jurassic rift basins progressed onto regional widespread acid lavas and were infilled by lagoonal organic-rich sequences. Early drift phase built basins transverse to the margin, with fluvio-lacustrine sequences: Salado, Colorado, Valdes-Rawson, San Julian and North Malvinas intracratonic basins, which underwent transtensional faulting. Post-Oxfordian to Neocomian brackish sequences, onlapped the conjugate basins during the margin`s drift, with petroleum systems, as in Austral and Malvinas. In the Valanginian, basic extrusions commenced to form on the continental border, heralding the oceanic phase. Due to thermal subsidence, offlaping sediments prograded onto the remaining half-grabens. Several petroleum systems, proven and hypothetical, are identified in this region.

Generalized Iterative Annealing Model for the action of RNA chaperones  

E-Print Network (OSTI)

As a consequence of the rugged landscape of RNA molecules their folding is described by the kinetic partitioning mechanism according to which only a small fraction ($\\phi_F$) reaches the folded state while the remaining fraction of molecules is kinetically trapped in misfolded intermediates. The transition from the misfolded states to the native state can far exceed biologically relevant time. Thus, RNA folding in vivo is often aided by protein cofactors, called RNA chaperones, that can rescue RNAs from a multitude of misfolded structures. We consider two models, based on chemical kinetics and chemical master equation, for describing assisted folding. In the passive model, applicable for class I substrates, transient interactions of misfolded structures with RNA chaperones alone are sufficient to destabilize the misfolded structures, thus entropically lowering the barrier to folding. For this mechanism to be efficient the intermediate ribonucleoprotein (RNP) complex between collapsed RNA and protein cofactor ...

Introduction The folded-coaxial line is an alternative for the 38.9 MHz capacitively-loaded coaxial cavity suggested in L8-26 l for the early part of the booster acceleration cycle. The folded coaxial line was investigated for two reasons: (1) in principle, less circumferential length is required by the folded coaxial line and: (2) the higher-order-mode structure is different and might be easier to damp than the capacitively-loaded coaxial cavity. The cross section of the folded coaxial line is shown in Figure 1. The ratios of rmi/rio and roo/rmo are the same to maintain a constant impedance between the outer and inner coaxial sections.

Diversity in Free Energy Landscape of Proteins with the Same Native Topology  

E-Print Network (OSTI)

In order to elucidate the role of the native state topology and the stability of subdomains in protein folding, we investigate free energy landscape of human lysozyme, which is composed of two subdomains, by Monte Carlo simulations. A realistic lattice model with Go-like interaction is used. We take the relative interaction strength (stability, in other word) of two subdomains as a variable parameter and study the folding process. A variety of folding process is observed and we obtained a phase diagram of folding in terms of temperature and the relative stability. Experimentally-observed diversity in folding process of c-type lysozimes is thus understood as a consequence of the difference in the relative stability of subdomains.

Gravity and ground magnetic surveys of the Thermo Hot Springs KGRA region, Beaver County, Utah  

DOE Green Energy (OSTI)

During the period June to September 1976, gravity and ground magnetic surveys were made in the Thermo Hot Springs KGRA region which is located southwest of the town of Milford, Beaver County, Utah. The regional surveys comprised 273 new gravity and magnetic stations and incorporated 104 previous gravity stations over an area of approximately 620 km{sup 2}. The detailed surveys consisted of 9 east-west profiles in the immediate vicinity of the Thermo Hot Springs KGRA. The gravity data were reduced and are presented as terrain-corrected Bouguer gravity anomaly maps. Terrain corrections were made to a distance of 18.8 km. The regional gravity map shows the following features: (1) a large north-south trend with total relief of 5 mgal extending through the central portion of the study area; (2) an east-west trend with relief of about 7-8 mgal south of the Star Range and Shauntie Hills; (3) a north-south trend with 5 mgal relief east of Blue Mountain; and (4) a broad low of approximately 5 mgal closure southwest of the Shauntie Hills. The trends are probably caused by major faults and the gravity low is probably caused by the southern end of the Wah Wah Valley graben. The detailed gravity map indicates two possible east-west trending faults intersecting a major north-south trending fault in the immediate vicinity of the Thermo Hot Springs. The location of the hot springs appears to be fault controlled. To facilitate interpretation of the gravity data, the following processing and modeling techniques were used: (1) high-pass frequency filtering; (2) polynomial fitting; (3) second derivative; (4) strike filtering; (5) two-dimensional modeling; and (6) three-dimensional modeling. These techniques proved helpful as they more clearly delineated features of interest. The residual maps outlined an elongate north-south graben that extends through the survey area. The strike-filtered maps emphasize the major north-south and east-west faults of the region. Modeling provided reasonable depth estimates for bedrock in the vicinity of the hot springs and supported the structural interpretation for the hot springs area. The magnetic data are presented as total magnetic intensity anomaly maps for both the regional and detailed surveys. The regional map delineates a magnetic high with 600-gammas closure that corresponds to a Tertiary quartz monzonite intrusive in the northeast part of the survey area. An east-west trend with about 300-gammas relief is delineated south of the Shauntie Hills and Star Range and possibly corresponds to an east-west fault. The detailed magnetic map outlines an anomalous low with nearly 100-gammas closure associated with the Thermo Hot Springs. This magnetic low may reflect an alteration zone which is structurally controlled. The following processing and modeling techniques were applied to aid interpretation of the magnetic data: (1) low-pass frequency filtering; (2) strike-filtering; (3) pseudogravity; (4) two and one-half dimensional modeling; and (5) three-dimensional modeling. The low-pass filtering clearly delineates the intrusive and the east-west trend south of the Star Range. The strike-filtering outlines north-south and east-west trends which correlate with faults implied by gravity data. The pseudogravity map indicates that the magnetic and gravity anomalies are not caused by the same bodies. The two and one-half dimensional modeling in the hot springs area provides a possible model for an alteration zone which appears to be structurally controlled. The three-dimensional model of the Tertiary quartz monzonite intrusive indicates a relatively shallow, slightly elongate intrusion that continues to a depth of at least 1 km.

Cold Electronstatic Ion Cyclotron Waves for Preionization and IBW Launching in LHD  

Science Conference Proceedings (OSTI)

A folded waveguide with E|| polarization is being installed on LHD device. The main purpose of the folded waveguide is to pre-ionize and create good target plasmas. The present manuscript proposes a launching of IBW via CESICW (Cold Electrostatic Ion Cyclotron Wave) for heating the core of LHD with the folded waveguide. The core heating can be accomplished by adding a minority hydrogen ion species in a helium majority plasma facilitating the mode-transformation of CESICW into IBW at the ion-ion hybrid resonance.

Apo and InsP[subscript 3]-bound crystal structures of the ligand-binding domain of an InsP[subscript 3] receptor  

Science Conference Proceedings (OSTI)

We report the crystal structures of the ligand-binding domain (LBD) of a rat inositol 1,4,5-trisphosphate receptor (InsP{sub 3}R) in its apo and InsP{sub 3}-bound conformations. Comparison of these two conformations reveals that LBD's first {beta}-trefoil fold ({beta}-TF1) and armadillo repeat fold (ARF) move together as a unit relative to its second {beta}-trefoil fold ({beta}-TF2). Whereas apo LBD may spontaneously transition between gating conformations, InsP{sub 3} binding shifts this equilibrium toward the active state.

Deltaic sedimentation in saline, alkaline Lake Bogoria, Kenya: Response to environmental change  

Science Conference Proceedings (OSTI)

Lake Bogoria is a meromictic, saline (90 g/l TDS), alkaline (pH: 10.3) lake with Na-CO[sub 3]-Cl waters, located in a narrow half-graben in the central Kenya Rift. It is fed by hot springs, direct precipitation, and a series of ephemeral streams that discharge into the lake via small deltas and fan-deltas. Examination of the exposed deltas and >50 short cores from the lake floor, have revealed a wide range of deltaic and prodeltaic sediments, including turbidites and subaqueous debris-flow deposits. Studies of 3 long cores and the exposed delta stratigraphy have shown how the style of deltaic sedimentation has responded to environmental changes during the last 30,000 years. During humid periods when lake level is high the lake waters are fresher and less dense. Theoretically, high sediment yield and more constant discharge may promote underflow (hyperpycnal flow), generating low-density turbidity currents. In contrast, during low stages with dense brine, the less dense, inflowing waters carry fine sediment plumes toward the center of the lake where they settle from suspension (hypopycnal flow). Although applicable as a general model, the sediment record shows that reality is more complex. Variations in meromixis and level of the chemocline, together with local and temporal differences in sediment yield and discharge, may permit density flows even when the lake is under a predominant hypopycnal regime. During periods of aridity when sodium carbonate evaporites were forming, exposed delta plains were subject to desiccation with local development of calcrete and zeolitic paleosols.

Geothermal investigations in Idaho. Part 5. Geochemistry and geologic setting of the thermal waters of the northern Cache Valley area, Franklin County, Idaho  

DOE Green Energy (OSTI)

The thermal waters of the north-south trending graben structure known as northern Cache Valley in southeastern Idaho were sampled during the summer and fall of 1973. Geologic and gravity data for the area indicate fault control for nearly all thermal water occurrences. Thermal-water discharges are generally restricted to the course of the Bear River with few known in areas away from the river. Spring deposits in the form of travertine may not be indications of low temperature thermal waters because abundant limestone and dolomite make up the geologic framework. Much gas, believed to consist mostly of carbon dioxide, is being evolved from many of the springs. The hottest water is found near Battle Creek and Squaw hot springs approximately 4 kilometers northwest of the town of Preston. Metoric waters descend along fault planes, fractures, and fissures to depths at which they are heated by increasing rock temperatures (geothermal gradient of 5/sup 0/C per 100 meters). Due to decreased density, the heated waters rise along the same or adjacent fault planes to the surface. The quartz equilibrium geochemical thermometer applied to the thermal water discharges indicates temperatures approaching 150/sup 0/C may be encountered by deep drilling. Mixing models, based on quartz solubility, indicate higher aquifer temperatures than the quartz equilibrium thermometer, but chloride concentration vs. temperature plots are not linear. The sodium-potassium-calcium geochemical thermometer indicates higher temperatures than quartz equilibrium and mixing models. The thermal waters are higher in total dissolved solids (12,000 to 13,000 milligrams per liter) than are known elsewhere in Idaho and represent potential pollution hazards should large scale withdrawal be attempted.

Intracaldera volcanism and sedimentation-Creede caldera, Colorado  

DOE Green Energy (OSTI)

Within the Creede caldera, Colorado, many of the answers to its postcaldera volcanic and sedimentary history lie within the sequence of tuffaceous clastic sedimentary rocks and tuffs known as the Creede Formation. The Creede Formation and its interbedded ash deposits were sampled by research coreholes Creede 1 and 2, drilled during the fall of 1991. In an earlier study of the Creede Formation, based on surface outcrops and shallow mining company coreholes, Heiken and Krier (1987) concluded that the process of caldera structural resurgence was rapid and that a caldera lake had developed in an annulus (``moat``) located between the resurgent dome and caldera wall. So far we have a picture of intracaldera activity consisting of intermittent hydrovoleanic eruptions within a caldera lake for the lower third of the Creede Formation, and both magmatic and hydrovolcanic ash eruptions throughout the top two-thirds. Most of the ash deposits interbedded with the moat sedimentary rocks are extremely fine-grained. Ash fallout into the moat lake and unconsolidated ash eroded from caldera walls and the slopes of the resurgent dome were deposited over stream delta distributaries within relatively shallow water in the northwestern moat, and in deeper waters of the northern moat, where the caldera was intersected by a graben. Interbedded with ash beds and tuffaceous siltstones are coarse-grained turbidites from adjacent steep slopes and travertine from fissure ridges adjacent to the moat. Sedimentation rates and provenance for clastic sediments are linked to the frequent volcanic activity in and near the caldera; nearly all of the Creede Formation sedimentary rocks are tuffaceous.

Assessment of the geothermal potential of southwestern New Mexico. Final report, July 1, 1978-April 30, 1980  

DOE Green Energy (OSTI)

Results are reported of geologic mapping of geothermal anomalies in the Gila Hot Springs KGRA/Mimbres Hot Springs area, Grant County. They suggest that both hot-spring occurrences are structurally controlled by the intersection of a major Basin and Range fault and the disturbed margin of an ash-flow tuff cauldron. Hydrothermal alteration in both areas is related to mid-Tertiary volcanism, not to modern hot springs. At Gila Hot Springs, the geothermal aquifer is a zone at the contact between the unwelded top of a major ash-flow tuff sheet (Bloodgood Canyon Rhyolite Tuff) and a succession of interlayered vesicular basaltic andesite flows and thin sandstone beds (Bearwallow Mountain Formation). Scattered groups of natural hot springs occur at intersections of this zone and the faults bordering the northeastern side of the Gila Hot Springs graben. Hydrothermal alteration of Bloodgood Canyon Rhyolite Tuff near major faults seems to have increased its permeability. At Mimbres Hot Springs, a single group of hot springs is controlled by the intersection of the Mimbres Hot Springs fault and a fractured welded ash-flow tuff that fills the Emory cauldron (Kneeling Nun Tuff). Gila Hot Springs and Mimbres Hot Springs do not seem to be connected by throughgoing faults. At both localities, hot spring water is used locally for space heating and domestic hot water; at Gila Hot Springs, water of 65.6/sup 0/C (150/sup 0/F) is used to generate electricity by means of a 10 kw freon Rankine Cycle engine. This is the first such application in New Mexico.

Geothermal potential for commercial and industrial direct heat applications in Salida, Colorado. Final report  

DOE Green Energy (OSTI)

The Salida Geothermal Prospect (Poncha Hot Springs) was evaluated for industrial and commercial direct heat applications at Salida, Colorado, which is located approximately five miles east of Poncha Hot Springs. Chaffee Geothermal, Ltd., holds the geothermal leases on the prospect and the right-of-way for the main pipeline to Salida. The Poncha Hot Springs are located at the intersection of two major structural trends, immediately between the Upper Arkansas graben and the Sangre de Cristo uplift. Prominent east-west faulting occurs at the actual location of the hot springs. Preliminary exploration indicates that 1600 gpm of geothermal fluid as hot as 250/sup 0/F is likely to be found at around 1500 feet in depth. The prospective existing endusers were estimated to require 5.02 x 10/sup 10/ Btu per year, but the total annual amount of geothermal energy available for existing and future endusers is 28.14 x 10/sup 10/ Btu. The engineering design for the study assumed that the 1600 gpm would be fully utilized. Some users would be cascaded and the spent fluid would be cooled and discharged to nearby rivers. The economic analysis assumes that two separate businesses, the energy producer and the energy distributor, are participants in the geothermal project. The producer would be an existing limited partnership, with Chaffee Geothermal, Ltd. as one of the partners; the distributor would be a new Colorado corporation without additional income sources. Economic evaluations were performed in full for four cases: the Base Case and three alternate scenarios. Alternate 1 assumes a three-year delay in realizing full production relative to the Base Case; Alternate 2 assumes that the geothermal reservoir is of a higher quality than is assumed for the Base Case; and Alternate 3 assumes a lower quality reservoir. 11 refs., 34 figs., 40 tabs.

The Cove Fort-Sulphurdale KGRA, a geologic and geophysical case study  

DOE Green Energy (OSTI)

Geological, geochemical and geophysical data are presented for one of the major geothermal systems in the western United States. Regional data indicate major tectonic structures which are still active and provide the conduits for the geothermal system. Detailed geologic mapping has defined major glide blocks of Tertiary volcanics which moved down from the Tushar Mountains and locally act as a leaky cap to portions of the presently known geothermal system. Mapping and geochemical studies indicate three periods of mineralization have affected the area, two of which are unrelated to the present geothermal activity. The geologic relationships demonstrate that the major structures have been opened repeatedly since the Tertiary. Gravity and magnetic data are useful in defining major structures beneath alluvium and basalt cover, and indicate the importance of the Cove Fort-Beaver graben and the Cove Creek fault in localizing the geothermal reservoir. These structures and a high level of microearthquake activity also suggest other target areas within the larger thermal anomaly. Electrical resistivity surveys and thermal gradient holes both contribute to the delineation of the known reservoir. Deep exploration wells which test the reservoir recorded maximum temperatures of 178 C and almost isothermal behavior beginning at 700 to 1000 m and continuing to a depth of 1800 m. Costly drilling, high corrosion rates and low reservoir pressure coupled with the relatively low reservoir temperatures have led to the conclusion that the reservoir is not economic for electric power production at present. Plans are underway to utilize the moderate-temperature fluids for agribusiness, and exploration continues for a deep high-temperature reservoir.

Anomalous zones in Gulf Coast Salt domes with special reference to Big Hill, TX, and Weeks Island, LA  

Science Conference Proceedings (OSTI)

Anomalous features in Gulf Coast Salt domes exhibit deviations from normally pure salt and vary widely in form from one dome to the next, ranging considerably in length and width. They have affected both conventional and solution mining in several ways. Gas outbursts, insolubles, and potash (especially carnallite) have led to the breakage of tubing in a number of caverns, and caused irregular shapes of many caverns through preferential leaching. Such anomalous features essentially have limited the lateral extent of conventional mining at several salt mines, and led to accidents and even the closing of several other mines. Such anomalous features, are often aligned in anomalous zones, and appear to be related to diapiric processes of salt dome development. Evidence indicates that anomalous zones are found between salt spines, where the differential salt intrusion accumulates other materials: Anhydrite bands which are relatively strong, and other, weaker impurities. Shear zones and fault displacement detected at Big Hill and Weeks Island domes have not yet had any known adverse impacts on SPR oil storage, but new caverns at these sites conceivably may encounter some potentially adverse conditions. Seismic reflection profiles at Big Hill dome have shown numerous fractures and faults in the caprock, and verified the earlier recognition of a major shear zone transecting the entire salt stock and forming a graben in the overlying caprock. Casing that is placed in such zones can be at risk. Knowledge of these zones should create awareness of possible effects rather than preclude the future emplacement of caverns. To the extent possible, major anomalous zones and salt stock boundaries should be avoided. Shear zones along overhangs may be particularly hazardous, and otherwise unknown valleys in the top of salt may occur along shear zones. These zones often can be mapped geophysically, especially with high-resolution seismic techniques.

Shale gas in the southern central area of New York State: Part II. Experience of locating and drilling four shale-gas wells in New York State  

Science Conference Proceedings (OSTI)

Four shale-gas wells have been located and drilled in the south-central area of New York State as part of this project. The four wells that were drilled are: the Rathbone well, in Steuben County, was located on the north side of a graben, in an old shale-gas field; it penetrated the Rhinestreet, Geneseo and Marcellus shales. Artificial stimulation was performed in the Rhinestreet, without marked success, and in the Marcellus; the latter formation has a calculated open flow of 110 Mcf/day and appears capable of initial production of 100 Mcf/day against a back-pressure of 500 psi. The Dansville well, in Livingston County, tested the Geneseo and Marcellus shales at shallower depth. Artificial stimulation was performed in the Marcellus. The calculated open flow is 95 Mcf/day, and the well appears capable of initial production of 70 Mcf/day against a back-pressure of 300 psi. The Erwin and N. Corning wells, both near Corning in Steuben County, were designed to test the possibility of collecting gas from a fractured conduit layer connecting to other fracture systems in the Rhinestreet shale. The N. Corning well failed; the expected conduit was found to be only slightly fractured. The Erwin well encountered a good initial show of gas at the conduit, but the gas flow was not maintained; even after artificial stimulation the production is only 10 Mcf/day. The present conclusion is that the most likely source of shale gas in south-central New York is the Marcellus shale formation. Important factors not yet established are the decline rate of Marcellus production and the potential of the Geneseo after stimulation.

Geology and geothermal resources of the Santiam Pass area of the Oregon Cascade Range, Deschutes, Jefferson and Linn Counties, Oregon  

DOE Green Energy (OSTI)

This open-file report presents the results of the Santiam Pass drilling program. The first phase of this program was to compile all available geological, geophysical and geothermal data for the Santiam Pass area and select a drill site on the basis of these data (see Priest and others, 1987a), A summary of the drilling operations and costs associated with the project are presented in chapter 1 by Hill and Benoit. An Overview of the geology of the Santiam Pass area is presented by Hill and Priest in chapter 2. Geologic mapping and isotopic age determinations in the Santiam Pass-Mount Jefferson area completed since 1987 are summarized in chapter 2. One of the more important conclusions reached in chapter 2 is that a minimum of 2 km vertical displacement has occurred in the High Cascade graben in the Santiam Pass area. The petrology of the Santiam Pass drill core is presented by Hill in chapter 3. Most of the major volcanic units in the core have been analyzed for major, minor, and trace element abundances and have been studied petrographically. Three K-Ar ages are interpreted in conjunction with the magnetostratigraphy of the core to show that the oldest rocks in the core are approximately 1.8 Ma. Geothermal and geophysical data collected from the Santiam Pass well are presented by Blackwell in chapter 4. The Santiam Pass well failed to penetrate beneath the zone of lateral groundwater flow associated with highly permeable Quaternary volcanic rocks. Calculated geothermal gradients range from about 50[degree]C/km at depth 700-900 m, to roughly 110[degree]C/km from 900 m to the bottom of the well at 929 m. Heat-flow values for the bottom part of the hole bracket the regional average for the High Cascades. Blackwell concludes that heat flow along the High Cascades axis is equal to or higher than along the western edge of the High Cascades.

Geology and geothermal resources of the Santiam Pass area of the Oregon Cascade Range, Deschutes, Jefferson and Linn Counties, Oregon. Final report  

DOE Green Energy (OSTI)

This open-file report presents the results of the Santiam Pass drilling program. The first phase of this program was to compile all available geological, geophysical and geothermal data for the Santiam Pass area and select a drill site on the basis of these data (see Priest and others, 1987a), A summary of the drilling operations and costs associated with the project are presented in chapter 1 by Hill and Benoit. An Overview of the geology of the Santiam Pass area is presented by Hill and Priest in chapter 2. Geologic mapping and isotopic age determinations in the Santiam Pass-Mount Jefferson area completed since 1987 are summarized in chapter 2. One of the more important conclusions reached in chapter 2 is that a minimum of 2 km vertical displacement has occurred in the High Cascade graben in the Santiam Pass area. The petrology of the Santiam Pass drill core is presented by Hill in chapter 3. Most of the major volcanic units in the core have been analyzed for major, minor, and trace element abundances and have been studied petrographically. Three K-Ar ages are interpreted in conjunction with the magnetostratigraphy of the core to show that the oldest rocks in the core are approximately 1.8 Ma. Geothermal and geophysical data collected from the Santiam Pass well are presented by Blackwell in chapter 4. The Santiam Pass well failed to penetrate beneath the zone of lateral groundwater flow associated with highly permeable Quaternary volcanic rocks. Calculated geothermal gradients range from about 50{degree}C/km at depth 700-900 m, to roughly 110{degree}C/km from 900 m to the bottom of the well at 929 m. Heat-flow values for the bottom part of the hole bracket the regional average for the High Cascades. Blackwell concludes that heat flow along the High Cascades axis is equal to or higher than along the western edge of the High Cascades.

Electromagnetic soundings over a geothermal reservoir in Dixie Valley, Nevada  

DOE Green Energy (OSTI)

An electromagnetic (EM) sounding survey was performed over a region encompassing the Dixie Valley geothermal field with the purpose of mapping the subsurface resistivity in the geothermal field and its surroundings. The EM survey consisted of 19 frequency-domain depth soundings made with the EM-60 system using three separate horizontal-loop transmitters, and was designed to explore a narrow region adjacent to the Stillwater Range to a depth of 2 to 3 k. Most sounding curves could be fitted to three-layer resistivity models. The surface layer is moderately conductive (10 to 15 ohm-m), has a maximum thickness of 500 m, and consists mainly of alluvial fan and lake sediments. More conductive zones are associated with hydrothermally altered rocks; a resistivity high may be associated with siliceous hot spring deposits. The conductive second layer (2 to 5 ohm-m) varies in thickness from 400 to 800 m and thickens toward the center of the valley. This layer probably consists of lacustrine sediments saturated with saline waters. Local resistivity lows observed in the second layer may be related to elevated subsurface temperatures. This layer may act as a cap rock for the geothermal system. Resistivities of the third layer are high (50 to 100 ohm-m) except in a narrow 5-km band paralleling the range front. This low-resistivity zone, within volcanic rocks, correlates well in depth and location with reported zones of geothermal fluid production. It also seems to correlate with the western margin of a concealed graben structure previously inferred from other geophysical data.

ADVANCED CHARACTERIZATION OF FRACTURED RESERVOIRS IN CARBONATE ROCKS: THE MICHIGAN BASIN  

Science Conference Proceedings (OSTI)

Progress in year 2 of this project is highlighted by the completing of the writing and testing of the project database, ''Atlas'', and populating it with all the project data gathered to date. This includes digitization of 17,000+ original Scout Tickets for the Michigan Basin. Work continues on the Driller's Reports, where they have scanned about 50,000 pages out of an estimated 300,000 pages. All of the scanned images have been attached to ''Atlas'', the visual database viewer developed for this project. A complete set of the 1/24,000 USGS DEM (Digital Elevation Models) for the State of Michigan has been downloaded from the USGS Web sites, decompressed and converted to ArcView Grid files. A large-scale map (48 inches x 84 inches) has been constructed by mosaicking of the high-resolution files. This map shows excellent ground surface detail and has drawn much comment and requests for copies at the venues where it has been displayed. Although it was generated for mapping of surface lineations the map has other uses, particularly analysis of the glacial drift in Michigan. It presents unusual problems due to its size and they are working with vendors on compression and display algorithms (e.g. MrSID{copyright}) in an attempt to make it available over the Internet, both for viewing and download. A set of aeromagnetic data for the Michigan Basin has been acquired and is being incorporated into the study. As reported previously, the general fracture picture in the Michigan Basin is a dominant NW-SE trend with a conjugate NE-SW trend. Subsurface, DEM and gravity data support the interpretation of a graben-type deep basement structural trend coincident with the Michigan Basin Gravity High. They plan to incorporate the aeromagnetic data into this interpretation as well.

The electrochemical cell includes folded electrode portions which form a plane recessed from the end of the electrode stack. The folded electrode portions are preferably formed by making pairs of slits in the electrode end and bending over the electrode portions between each pair of slits. The recessed plane forms a large area to which a current collection tab is subsequently connected. A coating may be applied to the folded portions of the electrode to further increase the contact area with the current collection tab by eliminating the slight variations in the recessed plane which are due to the overlap of the folded electrode portions.

Explicit formulae for continued fractions with symmetric patterns in their partial quotients are constructed in the field of formal power series. Similar to the work of Cohn in 1996, which generalized the so-called folding lemma to {kappa}-fold symmetry, the notion of {kappa}-duplicating symmetric continued fractions is investigated using a modification of the 1995 technique due to Clemens, Merrill and Roeder.

Kinematic and Mechanical Reconstruction of Walker Ridge Structures, Deepwater Gulf of Mexico  

E-Print Network (OSTI)

Recent high-resolution seismic imaging has allowed detailed reconstruction of the relationship between fold development and crestal faulting of the Chinook and Cascade folds in the deepwater Gulf of Mexico. Using 3-D seismic and biostratigraphic data, we have found that (1) short wavelength (~2300m), small amplitude folds (~540m) within the upper Cretaceous and upper Jurassic stratigraphic sequences took place no later than the late Jurassic, (2) large wavelength and amplitude fold growth, starting in the early Cretaceous, was produced by salt withdrawal, and (3) periods of increased sedimentation, fold growth, and fault slip occurred during the middle Miocene and late Miocene. Although the dominant stage of long wavelength, large amplitude fold growth started around early Cretaceous, the development of the Cascade and Chinook structures was continuous, punctuated by episodes of accelerated growth during the middle Miocene at rates of 337 and 235 m/Ma in the Cascade and 203 and 230 m/Ma in the Chinook. A later event of accelerated growth occurred during the late Miocene at rates of 1038 m/Ma in the Cascade and 1189 m/Ma in the Chinook. Accompanying fold growth was sedimentation, which was highest at 1949 m/Ma in the Cascade and 2585 m/Ma in the Chinook. Although limb tilt rates varied through fold growth, the highest rates also occurred during the middle Miocene at 0.330 and 0.196 degree/Ma for the Cascade and Chinook, respectively with the development of crestal faults at maximum slip rates of 88 and 90 m/Ma.

Subsurface structure of the north Summit gas field, Chestnut Ridge anticline of the Appalachian Basin  

SciTech Connect

The Chestnut Ridge anticline is the westernmost of the High Plateau folds in southwestern Pennsylvania and north-central West Virginia that are detached primarily in the Marcellus Shale, and the Martinsburg, Salina, and Rome Formations. The primary, basal detachment at the Summit field occurs in the Salina salt. Production from fracture porosity in the Devonian Oriskany Sandstone commenced in 1936. During the late 1980s and early 1990s, 14 wells were drilled preparatory to conversion of the reservoir to gas storage. Schlumberger`s Formation MicroScanner (FMS) logs were run in each of these wells to provide information on the structural configuration and fracture patterns of the reservoir. These data indicate that two inward-facing, tight folds at the Oriskany level form the upper flanks and core of the anticline at the northern end of the field, whereas the main part of the field to the south is a comparatively simple, broad closure at the Oriskany level. The structure is a broad, slightly asymmetric open fold in the Mississippian Greenbrier Formation at the surface. Fracture patterns mapped using FMS logs indicate a complex fracture system which varies slightly along the trend of the fold and among the units analyzed, including the Helderberg Formation, Huntersville Chert, Oriskany Sandstone, and Onondaga Formation. An orthogonal joint system strikes toward the northwest and northeast slightly askew to the trend of the fold`s crestal trace. A similar, but more complex fracture pattern is found in an oriented core of these units.

Geologic Framework of the 2005 Keathley Canyon Geologic Framework of the 2005 Keathley Canyon Gas Hydrate Research Well, Northern Gulf of Mexico Authors: D.R. Hutchinson, P.E. Hart, T.S. Collett, K.M. Edwards, and D.C. Twichell, U.S. Geological Survey, and F. Snyder, WesternGeco-Schlumberger. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco, Mexico, May 22-25, 2007 (http://www.agu.org/meetings/ja07/ [external site]). Abstract: The project was located in the Casey Basin in the northern Gulf of Mexico at 1,335 m water depth. A grid of 2-D high-resolution multichannel seismic lines around the drill sites, targeted for imaging depths down to at least 1,000 m subbottom, reveals multiple disconformities that bound seven mappable seismic stratigraphic units. A major disconformity in the middle of the units stands out for its angular baselapping geometry. From the seismic and drilling data, three episodes of sedimentary deposition and deformation are inferred. The oldest episode consists of fine-grained muds deposited during a period of relative stability in the basin (Units E, F, and G). A second episode (Units C and D) consists of large vertical displacements associated with infilling and ponding of sediment. This second interval corresponds with intercalated fine and coarse-grained material in the drill hole, which sampled the thin edges of much thicker units. The final episode (Units A and B) occurred during much-subdued vertical displacement. Hemipelagic drape (Unit A) characterizes the modern seafloor deposits. The basin is mostly filled. Its sill is part of a subsiding graben that is only 10-20 m shallower than the deepest point in the basin, indicating that gravity-driven transport would mostly bypass the basin. Contemporary faulting along the basin margins has selectively reactivated an older group of faults. The intercalated sand and mud deposits of Units C and D are tentatively correlated with late Pleistocene deposition derived from the western shelf-edge delta/depocenter of the Mississippi River, which was probably most active from 320 ka to 70 ka (Winker and Booth, 2000). Gas hydrate occurs within near-vertical fractures in Units E and F of the oldest episode. The presence of sand within the gas hydrate stability zone is not sufficient to concentrate gas hydrate, even though dispersed gas hydrate occurs deeper in the fractured mud/clay-rich sections of Units E and F.

The global distribution of large subaerial distributary fluvial systems  

E-Print Network (OSTI)

Large subaerial distributary fluvial systems are cone-shaped, alluvial deposits that are ubiquitous features on Earth. These non-marine, non-lacustrine deposits have superficial similarities to small alluvial fans but are at a scale that is orders of magnitude larger. A variety of terms have been used to identify these features, including alluvial cone, inland delta, wet alluvial fan, humid alluvial fan, alluvial fan, subaerial fan, terminal fan, and megafan. The first systematic examination of these features was presented by Wilkinson et al. (1997). This thesis attempts to provide a more detailed characterization and classification of these features. Fourteen systems in South America, Africa, and Asia were examined using Shuttle photography and AVHRR imagery. This study included: (1) maps of each system and their global distribution, (2) morphometric analyses, (3) classifications by climate, geology, and hydrology, and (4) a comparison to other fluvial systems. These systems have areas 8,881 to 239,583 km², radii 130 to 806 km, and slopes 0.00006 to 0.00079. Active and former river channel patterns on these features suggest that they formed by the action of a single river avulsing across the feature. The area of these features is unrelated to the area of the upstream drainage basin, but is related to the size of the downstream basin. This sample of systems occurs in a variety of climates and in two different geologic settings - foreland basins and half graben. The rivers on all systems are orientated transverse to the trend of the adjacent mountain range or fault. A variety of channel patterns are found on these systems. Considering the definitions of alluvial fans, rivers, and deltas, these systems are best classified as a specific variety of alluvial fan. A new alluvial fan classification scheme more inclusive than that proposed by Stanistreet and McCarthy (1993) is needed. The adoption of a common term to describe these systems - such as megafan - would help to eliminate some of the definitional ambiguities between them and other alluvial fans. Knowledge of these features will enhance our ability to interpret analogous features in the rock record, including important petroleum and water aquifers (e.g., the Ogallala Formation).

Rock Physics Based Determination of Reservoir Microstructure for Reservoir Characterization  

E-Print Network (OSTI)

One of the most important, but often ignored, factors affecting the transport and the seismic properties of hydrocarbon reservoir is pore shape. Transport properties depend on the dimensions, geometry, and distribution of pores and cracks. Knowledge of pore shape distribution is needed to explain the often-encountered complex interrelationship between seismic parameters (e.g. seismic velocity) and the independent physical properties (e.g. porosity) of hydrocarbon reservoirs. However, our knowledge of reservoir pore shape distribution is very limited. This dissertation employs a pore structure parameter via a rock physics model to characterize mean reservoir pore shape. The parameter was used to develop a new physical concept of critical clay content in the context of pore compressibility as a function of pore aspect ratio for a better understanding of seismic velocity as a function of porosity. This study makes use of well log dataset from offshore Norway and from North Viking Graben in the North Sea. In the studied North Sea reservoir, porosity and measured horizontal permeability was found to increase with increasing pore aspect ratio (PAR). PAR is relatively constant at 0.23 for volumes of clay (V_cl) less than 32% with a significant decrease to 0.04 for V_cl above 32%. The point of inflexion at 32% in the PAR –V_cl plane is defined as the critical clay volume. Much of the scatters in the compressional velocity-porosity cross-plots are observed where V_cl is above this critical value. For clay content higher than the critical value, Hertz-Mindlin (HM) contact theory over-predicts compressional velocity (V_p) by about 69%. This was reduced to 4% when PAR distribution was accounted for in the original HM formulation. The pore structure parameter was also used to study a fractured carbonate reservoir in the Sichuan basin, China. Using the parameter, the reservoir interval can be distinguished from those with no fracture. The former has a pore structure parameter value that is ? 3.8 whereas it was < 3.8 for the latter. This finding was consistent with the result of fracture analysis, which was based on FMI image. The results from this dissertation will find application in reservoir characterization as the industry target more complex, deeper, and unconventional reservoirs.

Paul I. Freimuth Paul I. Freimuth Research Interests One aspect of our research program aims to understand the folding behavior of proteins during overexpression, when molecular chaperone activity may be limiting. Protein overexpression technology has greatly facilitated structural and functional analyses of individual proteins, and it will also be a key technology for large scale characterization of proteomes as planned in the DOE's GTL program, for example. Molecular chaperones promote folding by lowering the free energy barrier to the unfolding of intermediate states. Deficits in chaperone activity therefore can lead to the kinetic trapping of folding intermediates, which eventually may aggregate. Our recent studies suggest that intramolecular electrostatic attractive and repulsive forces may be important factors in determining the

Importance of counteranions on the hydration structure of the curium ion  

SciTech Connect

Using density functional theory based ab initio molecular dynamics and metadynamics we show that counter ions can trigger noticeable changes in the hydration shell structure of the curium ion. The free energies of curium-water coordination and the solvent hydrogen bond (HB) lifetimes in the absence and presence the counter anions predict that chloride and bromide counter anions strengthen the first shell and consequently the 8-fold coordination state is dominant by at least 98%. In contrast, the perchlorate counter anions are found to weaken the coordination shell and the HB network, with the 9-fold and 8-fold states existing in an 8:1 ratio, which is in good agreement with reported 9:1 ratio seen in time resolved fluorescence spectroscopy experiments. To our knowledge this is the first time molecular simulations have shown that counter anions can directly affect the first hydration shell structure of a cation.

Generalized Iterative Annealing Model for the action of RNA chaperones  

E-Print Network (OSTI)

As a consequence of the rugged landscape of RNA molecules their folding is described by the kinetic partitioning mechanism according to which only a small fraction ($\\phi_F$) reaches the folded state while the remaining fraction of molecules is kinetically trapped in misfolded intermediates. The transition from the misfolded states to the native state can far exceed biologically relevant time. Thus, RNA folding in vivo is often aided by protein cofactors, called RNA chaperones, that can rescue RNAs from a multitude of misfolded structures. We consider two models, based on chemical kinetics and chemical master equation, for describing assisted folding. In the passive model, applicable for class I substrates, transient interactions of misfolded structures with RNA chaperones alone are sufficient to destabilize the misfolded structures, thus entropically lowering the barrier to folding. For this mechanism to be efficient the intermediate ribonucleoprotein (RNP) complex between collapsed RNA and protein cofactor should have optimal stability. We also introduce an active model (suitable for stringent substrates with small $\\phi_F$), which accounts for the recent experimental findings on the action of CYT-19 on the group I intron ribozyme, showing that RNA chaperones does not discriminate between the misfolded and the native states. In the active model, the RNA chaperone system utilizes chemical energy of ATP hydrolysis to repeatedly bind and release misfolded and folded RNAs, resulting in substantial increase of yield of the native state. The theory outlined here shows, in accord with experiments, that in the steady state the native state does not form with unit probability.

Euclidean SYM Theories by Time Reduction and Special Holonomy Manifolds  

E-Print Network (OSTI)

Euclidean supersymmetric theories are obtained from Minkowskian theories by performing a reduction in the time direction. This procedure elucidates certain mysterious features of Zumino's N=2 model in four dimensions, provides manifestly hermitian Euclidean counterparts of all non-mimimal SYM theories, and is also applicable to supergravity theories. We reanalyse the twists of the 4d N=2 and N=4 models from this point of view. Other applications include SYM theories on special holonomy manifolds. In particular, we construct a twisted SYM theory on Kaehler 3-folds and clarify the structure of SYM theory on hyper-Kaehler 4-folds.

Ion-mediated RNA structural collapse: effect of spatial confinement  

E-Print Network (OSTI)

RNAs are negatively charged molecules residing in macromolecular crowding cellular environments. Macromolecular confinement can influence the ion effects in RNA folding. In this work, using the recently developed tightly bound ion model for ion fluctuation and correlation, we investigate the confinement effect on the ion-mediated RNA structural collapse for a simple model system. We found that, for both Na$^+$ and Mg$^{2+}$, ion efficiencies in mediating structural collapse/folding are significantly enhanced by the structural confinement. Such an enhancement in the ion efficiency is attributed to the decreased electrostatic free energy difference between the compact conformation ensemble and the (restricted) extended conformation ensemble due to the spatial restriction.

Escherichia coli Enhanced Hydrogen Production, Genome-wide Screening for Extracellular DNA, and Influence of GGDEF Proteins on Early Biofilm Formation  

E-Print Network (OSTI)

Escherichia coli is the best characterized bacterium; it grows rapidly, and it is easy to manipulate genetically. An increased knowledge about the physiology of this model organism will facilitate the development of engineered E.coli strains for applications such as production of biofuels and biofilm control. The aims of this work were the application of protein engineering to increase E. coli hydrogen production, the identification of the proteins regulating extracellular DNA production (eDNA), and the evaluation of the effect of the proteins synthesizing the signal 3'-5'-cyclic diguanylic acid (c-di-GMP) on biofilm formation. The Escherichia coli hydrogen production rate was increased 9 fold through random mutagenesis of fhlA. Variant FhlA133 (Q11H, L14V, Y177F, K245R, M288K, and I342F) enhances hydrogen production by increasing transcription of the four transcriptional units regulated by FhlA. The amino acid replacements E363G and L14G in FhlA increased hydrogen production 6 fold and 4 fold, respectively. The complete E. coli genome was screened to identify proteins that affect eDNA production. The nlpI, yfeC, and rna mutants increased eDNA production and the hns and rfaD mutants decreased eDNA production. Deletion of nlpI increases eDNA 3 fold while overexpression of nlpI decreases eDNA 16 fold. Global regulator H-NS is required for eDNA with E. coli since deletion of hns abolished eDNA production while overexpression of hns restored eDNA to 70 percent of the wild-type levels. Our results suggest that eDNA production in E. coli is related to direct secretion. Deletions of the genes encoding the diguanylate cyclases YeaI, YedQ, and YfiN increased swimming motility and eDNA as expected for low c-di-GMP levels. However, contrary to the current paradigm, early biofilm formation increased dramatically for the yeaI (30 fold), yedQ (12 fold), and yfiN (18 fold) mutants. Hence, our results suggest that c-di-GMP levels should be reduced for initial biofilm formation because motility is important for initial attachment to a surface.

The loop quantum theory, which constitutes a very small discontinuous space, as new method is applied to biology. The model of protein folding and lungs is proposed. In the model, some known results are used, and four approximate conclusions are obtained: their structures are quantized, their space regions are finite, various singularities correspond to folding and crossed points, and different types of catastrophe exist. Further, based on the inseparability and correlativity of the biological systems, the nonlinear whole biology is proposed, and four basic hypotheses are formed. It may unify reductionism and holism, structuralism and functionalism. Finally, the medical meaning of the theory is discussed briefly.

A temperature responsive thermionic gas switch having folded electron emitting surfaces. An ionizable gas is located between the emitter and an interior surface of a collector, coaxial with the emitter. In response to the temperature exceeding a predetermined level, sufficient electrons are derived from the emitter to cause the gas in the gap between the emitter and collector to become ionized, whereby a very large increase in current in the gap occurs. Due to the folded emitter surface area of the switch, increasing the "on/off" current ratio and adjusting the "on" current capacity is accomplished.

Image Recognition Techniques for Gamma Spectroscopy  

SciTech Connect

Photons, after generated from a radioactive source and before they deposit their energy in a photo detector, are subsequent to multiple scattering mechanisms. As a result, the measured energy from the photo detector is different from the energy the photon had when generated. This is known as folding of the photon energy. Moreover, statistical fluctuation inside the detector contribute to energy folding. In this work, a new method is presented for unfolding the gamma ray spectrum. The method uses a 2-dimensional representation of the measured spectrum (image) and then uses image recognition techniques, and especially differential edge detection, to generate the original spectrum.
