Revised age for Midway volcano, Hawaiian volcanic chain  

Science Journals Connector (OSTI)

New conventional K-Ar,40Ar/39Ar, and petrochemical data on alkalic basalt pebbles from the basalt conglomerate overlying tholeiitic flows in the Midway drill hole show that Midway evolved past the tholeiitic shield-building stage and erupted lavas of the alkalic suite27.0 ± 0.6m.y. ago. The data also show that previously published conventional K-Ar ages on altered samples of tholeiite are too young by about 9 m.y. These results remove a significant anomaly in the age-distance relationships of the Hawaiian chain and obviate the need for large changes in either the rate of rotation of the Pacific plate about the Hawaiian pole or the motion of the plate relative to the Hawaiian hot spot since the time of formation of the Hawaiian-Emperor bend. All of the age data along the Hawaiian chain are now reasonably consistent with an average rate of volcanic propagation of 8.0 cm/yr and with 0.83°/m.y. of angular rotation about the Hawaiian pole.

Hydrochemical features of a geothermal test well iin a volcanic caldera, MT. Pinatubo, Phillipines  

SciTech Connect (OSTI)

Mt. Pinatubo is one of several recent-age volcanoes along the west Luzon volcanic arc. A fumarole near the suminit emits gases with magmatic characteristics. Several thermal springs on the east and west flanks yield various fluid typos, including neutral chloride and bicarbonate. Three wellbores probed the Mt. Pinatubo caldera from elevations of +1230 through -1600 mRSL. Trajectories may be described as: central, crossing a boundary wall from the inside, and skirting a wall [probably] on the inside. Brine discharges indicate severe evapo-concentration effects accompanied by other phenomena. Severity of evapo-concentration indicates low fluid mobility near the wellbores. Large variations for ratios of component concentrations were observed, indicating negligible natural circulation (mixing). Implications about fluid movements and heat transfer processes are explored. Three components of steam can be quantified and all are significant: separate entry, adiabatic boiling, and boiling by rock heat.

The Plio–Quaternary volcanic evolution of Gran Canaria based on new K–Ar ages and magnetostratigraphy  

Science Journals Connector (OSTI)

The combined use of radiometric dating (51 new unspiked K–Ar ages), magnetostratigraphy and field geology establishes a new time framework for the last two stages of the volcanic evolution of Gran Canaria. Most of the dated samples have ages coherent with their stratigraphic positions and magnetic polarities. Our new set of data extends the end of the Roque Nublo (RN) group, one of the main posterosive stages of Gran Canaria which started about 4.9 Ma ago, to ages as young as 2.87 Ma. This is about 0.7 Ma younger than previously thought. Moreover, the dating of samples collected in well-defined stratigraphic sequences supports the contemporaneity of the early stages of the post-Roque Nublo group and the vanishing activity of the Roque Nublo stratovolcano between 3.7 and 2.9 Ma. The multiple lateral collapses of the Roque Nublo stratovolcano occurred during this period between 3.5 and 3.1 Ma which corresponds to a main period of volcanic quiescence. After 2.9 Ma, the effusive activity propagated along a well-defined NW–SE rift until about 1.5 Ma, shifting progressively from a rifting propagation to platform-forming lavas. Thereafter, the activity is very disperse and belongs to the Brunhes period, with most of it before 500 ka.

Usage of Red supergiant spectral features as age indicators in starburst regions  

E-Print Network [OSTI]

We investigate techniques that can be used to determine ages of starburst regions containing populations beyond their early nebular phase. In particular, we study the strength of the CaII triplet (lambda 8498, 8542, 8662 Ang) and the CO index (2.31-2.40 micron band) using synthetic models as the starburst evolves. For an instantaneous burst of star formation both of these absorption features remain strongest between 7-14 Myr corresponding to the red supergiant population. The detailed evolutionary behavior of the starburst is strongly metallicity dependent. Low metallicity starburst models successfully reproduce the distribution of equivalent widths of CaII triplet with age in Large Magellanic Cloud clusters. The clusters in the red supergiant phase strongly favor the stellar evolutionary models incorporating mass-loss rates higher than the standard values. We suggest usage of diagrams involving CaII triplet equivalent width, CO index and nebular recombination lines to infer the history as well as age of starburst regions.

The usage of the Asymptotic Giant Branch Star Features As Age Indicators in Post-Starburst Galaxies  

E-Print Network [OSTI]

We investigate techniques that can be used to determine ages of recently star forming regions during the phase dominated in the near-IR by the asymptotic giant branch stars (10^8-10^9 yrs). In particular, we present selected near-IR spectroscopic features that identify the contribution of O-rich and C-rich AGB variable stars to the integrated spectra of post-starbursts. The observational strategy based on those features is presented. We discuss the robustness of our selected features in constraining the ages of the post-starburst population depending on its physical environment and on underlying evolved populations. The interplay between the integrated features of populations and the stellar parameters is discussed.

DETECTING VOLCANISM ON EXTRASOLAR PLANETS  

SciTech Connect (OSTI)

The search for extrasolar rocky planets has already found the first transiting rocky super-Earth, Corot 7b, with a surface temperature that allows for magma oceans. Here, we investigate whether we could distinguish rocky planets with recent major volcanism by remote observation. We develop a model for volcanic eruptions on an Earth-like exoplanet based on the present-day Earth and derive the observable features in emergent and transmission spectra for multiple scenarios of gas distribution and cloud cover. We calculate the observation time needed to detect explosive volcanism on exoplanets in primary as well as secondary eclipse and discuss the likelihood of observing volcanism on transiting Earth-sized to super-Earth-sized exoplanets. We find that sulfur dioxide from large explosive eruptions does present a spectral signal that is remotely detectable especially for secondary eclipse measurements around the closest stars and ground-based telescopes, and report the frequency and magnitude of the expected signatures. The transit probability of a planet in the habitable zone decreases with distance from the host star, making small, nearby host stars the best targets.

Modeling volcanic ash dispersal  

ScienceCinema (OSTI)

Explosive volcanic eruptions inject into the atmosphere large amounts of volcanic material (ash, blocks and lapilli). Blocks and larger lapilli follow ballistic and non-ballistic trajectories and fall rapidly close to the volcano. In contrast, very fine ashes can remain entrapped in the atmosphere for months to years, and may affect the global climate in the case of large eruptions. Particles having sizes between these two end-members remain airborne from hours to days and can cover wide areas downwind. Such volcanic fallout entails a serious threat to aircraft safety and can create many undesirable effects to the communities located around the volcano. The assessment of volcanic fallout hazard is an important scientific, economic, and political issue, especially in densely populated areas. From a scientific point of view, considerable progress has been made during the last two decades through the use of increasingly powerful computational models and capabilities. Nowadays, models are used to quantify hazard scenarios and/or to give short-term forecasts during emergency situations. This talk will be focused on the main aspects related to modeling volcanic ash dispersal and fallout with application to the well known problem created by the Eyjafjöll volcano in Iceland. Moreover, a short description of the main volcanic monitoring techniques is presented.

Jasper Seamount: Seven million years of volcanism  

SciTech Connect (OSTI)

Jasper Seamount is a young, mid-sized (690 km{sup 3}) oceanic intraplate volcano located about 500 km west-southwest of San Diego, California. Reliable {sup 40}Ar/{sup 39}Ar age data were obtained for several milligram-sized samples of 4 to 10 Ma plagioclase by using a defocused laser beam to clean the samples before fusion. Gee and Staudigel suggested that Jasper Seamount consists of a transitional to tholeiitic shield volcano formed by flank transitional series lavas, overlain by flank alkalic series lavas and summit alkalic series lavas. Twenty-nine individual {sup 40}Ar/{sup 39}Ar laser fusion analyses on nine samples confirm the stratigraphy: 10.3-10.0 Ma for the flank transitonal series, 8.7-7.5 Ma for the flank alkalic series, and 4.8-4.1 Ma for the summit alkalic series. The alkalinity of the lavas clearly increases with time, and there appear to be 1 to 3 m.y. hiatuses between each series. The age data are consistent with the complex magnetic anomaly of Jasper; however the dominant reversed polarity inferred from the anomaly suggests that most of the seamount formed at ca. 11 Ma, prior to the onset of Chron C5N. The duration of volcanism of Jasper Seamount is slightly longer than the duration of volcanism at Hawaiian volcanoes, suggesting that individual age data from seamounts may constrain the age of a seamount only to within about 7 m.y. unless the stage of volcanism can be unambiguously determined. Extrapolating from the results of our study, similar precision in age determinations should be possible on 50 mg of 1 Ma plagioclase from mid-ocean ridge basalt, opening new possibilities in the geochronology of young, low-potassium volcanic rocks.

Origin and formation of neck in a basin landform: Examples from the Camargo volcanic field, Chihuahua (México)  

Science Journals Connector (OSTI)

The term “neck in a basin” (NIB) landform is proposed for volcanic structures characterized by nearly circular to elliptical open basins, located near the headwater of small streams or drainages, which contain small volcanic necks and/or erosion remnants of one (or more) cinder cones. NIB landforms are typically 400-1000 m in diameter and 30-100 m deep and are invariably surrounded by steep walls cut into one or more basaltic lava flows. NIB landforms lack evidence for a primary volcanogenic origin through either collapse or youthful eruptive activity. In the Pliocene portion (4 – 2 Ma) of the Plio-Quaternary Camargo volcanic field of Chihuahua (México), they are relatively numerous and are best developed at the margins of a gently sloping (3-5°) basaltic lava plateau and near major fault scarps. Mature NIB landforms have ring-like circular drainage patterns and central elevations marked by small volcanic necks and associated radial dikes intruded into basaltic scoria-fall and /or agglutinate deposits. We interpret NIB landforms to be erosional in origin. They develop where a cinder cone is surrounded by one or more sheet-like lava flows from one or more separate subsequent vents. Once eruptive activity ceases at the younger volcano(es), fluvial erosion gradually produces a ring-like drainage pattern along the contact between the lava and the older cinder cone. As a response to a marked contrast in resistance to erosion between lava flows and unconsolidated or poorly lithified pyroclastic deposits, the older cinder cone is preferentially eroded. In this manner, a ring-shaped, steep sided erosional basin, preformed by the scoria cone, is produced; eventually fluvial erosion exposes the central neck and dikes. The volume, relief, and age of the volcanic field are key factors in the formation and preservation of a NIB landform. They form in volcanic fields where lava emissions are sufficiently vigorous to engulf earlier cinder cones. Relief and associated high rates of fluvial erosion play an important role in NIB development, as demonstrated by their locations in the Camargo volcanic field. Fully developed NIB landforms are not found in Quaternary volcanic fields, probably because erosion has not had sufficient time to generate their characteristics features. NIB landforms are also absent in Miocene fields, because erosion has proceeded too far, and thus has completely removed any NIB landform that may once have existed. The Camargo volcanic field is the only major area of Pliocene intraplate eruptive activity in northern México, and the only place where NIB landforms are relatively abundant.

Volcanic studies at Katmai  

SciTech Connect (OSTI)

The Continental Scientific Drilling Program (CSDP) is a national effort supported by the Department of Energy, the US Geological Survey, and the National Science Foundation. One of the projects proposed for the CSDP consists of drilling a series of holes in Katmai National Park in Alaska to give a third dimension to the model of the 1912 eruption of Novarupta, and to investigate the processes of explosive volcanism and hydrothermal transport of metals (Eichelberger et al., 1988). The proposal for research drilling at Katmai states that ``the size, youth, elevated temperature, and simplicity of the Novarupta vent make it a truly unique scientific target.`` The National Park Service (NPS), which has jurisdiction, is sympathetic to aims of the study. However, NPS wishes to know whether Katmai is indeed uniquely suited to the research, and has asked the Interagency Coordinating Group to support an independent assessment of this claim. NPS suggested the National Academy of Sciences as an appropriate organization to conduct the assessment. In response, the National Research Council -- the working arm of the Academy -- established, under the aegis of its US Geodynamics Committee, a panel whose specific charge states: ``The proposed investigation at Katmai has been extensively reviewed for scientific merit by the three sponsoring and participating agencies. Thus, the scientific merit of the proposed drilling at Katmai is not at issue. The panel will review the proposal for scientific drilling at Katmai and prepare a short report addressing the specific question of the degree to which it is essential that the drilling be conducted at Katmai as opposed to volcanic areas elsewhere in the world.``

GIS methods applied to the degradation of monogenetic volcanic fields: A case study of the Holocene volcanism of Gran Canaria (Canary Islands, Spain)  

Science Journals Connector (OSTI)

Modeling of volcanic morphometry provides reliable measurements of parameters that assist in the determination of volcanic landform degradation. Variations of the original morphology enable the understanding of patterns affecting erosion and their development, facilitating the assessment of associated hazards. A total of 24 volcanic Holocene eruptions were identified in the island of Gran Canaria (Canary Islands, Spain). 87% of these eruptions occurred in a wet environment while the rest happened in a dry environment. 45% of Holocene eruptions are located along short barrancos (S-type, less than 10 km in length), 20% along large barrancos (L-type, 10–17 km in length) and 35% along extra-large barrancos (XL-type, more than 17 km in length). The erosional history of Holocene volcanic edifices is in the first stage of degradation, with a geomorphic signature characterized by a fresh, young cone with a sharp profile and a pristine lava flow. After intensive field work, a careful palaeo-geomorphological reconstruction of the 24 Holocene eruptions of Gran Canaria was conducted in order to obtain the Digital Terrain Models (DTMs) of the pre- and post-eruption terrains. From the difference between these DTMs, the degradation volume and the incision rate were obtained. The denudation of volcanic cones and lava flows is relatively independent both their geographical location and the climatic environment. However, local factors, such as pre-eruption topography and ravine type, have the greatest influence on the erosion of Holocene volcanic materials in Gran Canaria. Although age is a key factor to help understand the morphological evolution of monogenetic volcanic fields, the Gran Canaria Holocene volcanism presented in this paper demonstrates that local and regional factors may determine the lack of correlation between morphometric parameters and age. Consequently, the degree of transformation of the volcanic edifices evolves, in many cases, independently of their age.

Characterization of Io's volcanic activity by infrared polarimetry  

SciTech Connect (OSTI)

The thermal emission from Io's volcanic hot spots is linearly polarized.Infrared measurements at 4.76 micrometers show disk-integrated polarization as large as 1.6 percent. The degree and position angle of linear polarization vary with Io's rotation in a manner characteristic of emission from a small number of hot spots. A model incorporating three hot spots best fits the data. The largest of these hot spots lies to the northeast of Loki Patera, as mapped from Voyager, and the other spot on the trailing hemisphere is near Ra Patera. The hot spot on the leading hemisphere corresponds to no named feature on the Voyager maps. The value determined for the index of refraction of the emitting surface is a lower bound; it is similar to that of terrestrial basalts and is somewhat less than that of sulfur. 25 references.

ENGINEERED BARRIER SYSTEM FEATURES, EVENTS, AND PROCESSES  

SciTech Connect (OSTI)

This analysis report is one of the technical reports containing documentation of the Environmental Radiation Model for Yucca Mountain, Nevada (ERMYN), a biosphere model supporting the total system performance assessment (TSPA) for the license application (LA) for the Yucca Mountain repository. This analysis report describes the development of biosphere dose conversion factors (BDCFs) for the volcanic ash exposure scenario, and the development of dose factors for calculating inhalation dose during volcanic eruption. A graphical representation of the documentation hierarchy for the ERMYN is presented in Figure 1 - 1. This figure shows the interrelationships among the products (i.e., analysis and model reports) developed for biosphere modeling and provides an understanding of how this analysis report contributes to biosphere modeling. This report is one of two reports that develop biosphere BDCFs, which are input parameters for the TSPA model. The ''Biosphere Model Report'' (BSC 2004 [DIRS 169460]) describes in detail the ERMYN conceptual model and mathematical model. The input parameter reports, shown to the right of the Biosphere Model Report in Figure 1-1, contain detailed descriptions of the model input parameters, their development and the relationship between the parameters and specific features, events and processes (FEPs). This report describes biosphere model calculations and their output, the BDCFs, for the volcanic ash exposure scenario. This analysis receives direct input from the outputs of the ''Biosphere Model Report'' (BSC 2004 [DIRS 169460]) and from the five analyses that develop parameter values for the biosphere model (BSC 2005 [DIRS 172827]; BSC 2004 [DIRS 169672]; BSC 2004 [DIRS 169673]; BSC 2004 [DIRS 169458]; and BSC 2004 [DIRS 169459]). The results of this report are further analyzed in the ''Biosphere Dose Conversion Factor Importance and Sensitivity Analysis'' (Figure 1 - 1). The objective of this analysis was to develop the BDCFs for the volcanic ash exposure scenario and the dose factors for calculating inhalation doses during volcanic eruption (eruption phase of the volcanic event). For the volcanic ash exposure scenario, the mode of radionuclide release into the biosphere is a volcanic eruption through the repository with the resulting entrainment of contaminated waste in the tephra and the subsequent atmospheric transport and dispersion of contaminated material in the biosphere. The biosphere process model for this scenario uses the surface deposition of contaminated ash as the source of radionuclides in the biosphere. The initial atmospheric transport and dispersion of the ash as well as its subsequent redistribution by fluvial and aeolian processes are not addressed within the biosphere model. These processes influence the value of the source term that is calculated elsewhere and then combined with the BDCFs in the TSPA model to calculate expected dose to the receptor.

Evidence for explosive silicic volcanism on the Moon from the extended distribution of thorium near the Compton-Belkovich Volcanic Complex  

E-Print Network [OSTI]

We reconstruct the abundance of thorium near the Compton-Belkovich Volcanic Complex on the Moon, using data from the Lunar Prospector Gamma Ray Spectrometer. We enhance the resolution via a pixon image reconstruction technique, and find that the thorium is distributed over a larger (40 km $\\times$ 75 km) area than the (25 km $\\times$ 35 km) high albedo region normally associated with Compton-Belkovich. Our reconstructions show that inside this region, the thorium concentration is 15 - 33 ppm. We also find additional thorium, spread up to 300 km eastward of the complex at $\\sim$2 ppm. The thorium must have been deposited during the formation of the volcanic complex, because subsequent lateral transport mechanisms, such as small impacts, are unable to move sufficient material. The morphology of the feature is consistent with pyroclastic dispersal and we conclude that the present distribution of thorium was likely created by the explosive eruption of silicic magma.

Volcanic ash impacts on critical infrastructure  

Science Journals Connector (OSTI)

Volcanic eruptions can produce a wide range of hazards. Although phenomena such as pyroclastic flows and surges, sector collapses, lahars and ballistic blocks are the most destructive and dangerous, volcanic ash is by far the most widely distributed eruption product. Although ash falls rarely endanger human life directly, threats to public health and disruption to critical infrastructure services, aviation and primary production can lead to significant societal impacts. Even relatively small eruptions can cause widespread disruption, damage and economic loss. Volcanic eruptions are, in general, infrequent and somewhat exotic occurrences, and consequently in many parts of the world, the management of critical infrastructure during volcanic crises can be improved with greater knowledge of the likely impacts. This article presents an overview of volcanic ash impacts on critical infrastructure, other than aviation and fuel supply, illustrated by findings from impact assessment reconnaissance trips carried out to a wide range of locations worldwide by our international research group and local collaborators. ‘Critical infrastructure’ includes those assets, frequently taken for granted, which are essential for the functioning of a society and economy. Electricity networks are very vulnerable to disruption from volcanic ash falls. This is particularly the case when fine ash is erupted because it has a greater tendency to adhere to line and substation insulators, where it can cause flashover (unintended electrical discharge) which can in turn cause widespread and disruptive outages. Weather conditions are a major determinant of flashover risk. Dry ash is not conductive, and heavy rain will wash ash from insulators, but light rain/mist will mobilise readily-soluble salts on the surface of the ash grains and lower the ash layer’s resistivity. Wet ash is also heavier than dry ash, increasing the risk of line breakage or tower/pole collapse. Particular issues for water supply managers include: monitoring turbidity levels in raw water intakes, and if necessary increasing chlorination to compensate for higher turbidity; managing water demand; and communicating monitoring results with the public to allay fears of contamination. Ash can cause major damage to wastewater disposal systems. Ash deposited onto impervious surfaces such as roads and car parks is very easily washed into storm drains, where it can form intractable masses and lead to long-term flooding problems. It can also enter wastewater treatment plants (WWTPs), both through sewer lines and by direct fallout. Damage to modern \\{WWTPs\\} can run into millions of dollars. Ash falls reduce visibility creating hazards for ground transportation. Dry ash is also readily remobilised by vehicle traffic and wind, and dry and wet ash deposits will reduce traction on paved surfaces, including airport runways. Ash cleanup from road and airports is commonly necessary, but the large volumes make it logistically challenging. Vehicles are vulnerable to ash; it will clog filters and brake systems and abrade moving parts within engines. Lastly, modern telecommunications networks appear to be relatively resilient to volcanic ash fall. Signal attenuation and interference during ash falls has not been reported in eruptions over the past 20 years, with the exception of interference from ash plume-generated lightning. However, some telecommunications equipment is vulnerable to airborne ash, in particular heating, ventilation and air-conditioning (HVAC) systems which may become blocked from ash ingestion leading to overheating. This summary of volcanic ash impacts on critical infrastructure provides insight into the relative vulnerability of infrastructure under a range of different ashfall scenarios. Identifying and quantifying these impacts is an essential step in building resilience within these critical systems. We have attempted to consider interdependencies between sectors in a holistic way using systems thinking. As modern society becomes increasingly complex and interdependent this

The Lathrop Wells volcanic center: Status of field and geochronology studies  

SciTech Connect (OSTI)

The purpose of this paper is to describe the status of field and geochronology studies of the Lathrop Wells volcanic center. Our perspective is that it is critical to assess all possible methods for obtaining cross-checking data to resolve chronology and field problems. It is equally important to consider application of the range of chronology methods available in Quaternary geologic research. Such an approach seeks to increase the confidence in data interpretations through obtaining convergence among separate isotopic, radiogenic, and age-correlated methods. Finally, the assumptions, strengths, and weaknesses of each dating method need to be carefully described to facilitate an impartial evaluation of results. The paper is divided into two parts. The first part describes the status of continuing field studies for the volcanic center for this area south of Yucca Mountain, Nevada. The second part presents an overview of the preliminary results of ongoing chronology studies and their constraints on the age and stratigraphy of the Lathrop Wells volcanic center. Along with the chronology data, the assumptions, strengths, and limitations of each methods are discussed.

Mytko's time at the ALS was focused on 3D imaging and printing techniques. An integral part of the ISME program is educators taking their experiences back to the classroom through new curriculum development. As such, Mytko put together a program that would engage her students in collaborative proposal process similar to a typical ALS user proposal. Students worked in groups to craft proposals for scanning items of interest at the tomography beamline, a selection of which were chosen through a peer-review process and then scanned at Beamline 8.3.2. ALS beamline scientist Dula Parkinson worked with Mytko to develop the program and gave feedback on the kids' proposal, which Mytko says was thrilling for her students.

Basaltic volcanic episodes of the Yucca Mountain region  

SciTech Connect (OSTI)

The purpose of this paper is to summarize briefly the distribution and geologic characteristics of basaltic volcanism in the Yucca Mountain region during the last 10--12 Ma. This interval largely postdates the major period of silicic volcanism and coincides with and postdates the timing of major extensional faulting in the region. Field and geochronologic data for the basaltic rocks define two distinct episodes. The patterns in the volume and spatial distribution of these basaltic volcanic episodes in the central and southern part of the SNVF are used as a basis for forecasting potential future volcanic activity in vicinity of Yucca Mountain. 33 refs., 2 figs.

Fluvial dissection, isostatic uplift, and geomorphological evolution of volcanic islands (Gran Canaria, Canary Islands, Spain)  

Science Journals Connector (OSTI)

Digital analysis of torrential gullies (‘barrancos’) deeply incised into the volcanic Island of Gran Canaria (Canary Islands) allows us to extract the longitudinal profiles and pre-incision surfaces for individual basins, from which morphometric parameters (length, elevation, area, slope) have been calculated. Other derived parameters, such as ridgeline profiles, maximum incision values, volume removed by fluvial erosion, geophysical relief and isostatic uplift, have also been computed. Based on K/Ar ages for the island, well-constrained incision-uplift rates have been calculated by means of the combination of different methodological approaches commonly used in orogens and large mountain ranges. The geomorphological and morphometric analyses reveal that the island is clearly divided into four environmental quadrants determined by the combination of a couple of key-factors: the age of the volcanic surfaces and the climatic conditions. These factors determine a young sector covered with Plio-Quaternary platform-forming lavas (finished at 1.9–1.5 Ma) evolving under contrasting wet (NE) to dry (SE) climates, and an older sector, conserving the residual surfaces of the Miocene shield building (14.5–8.7 Ma) at the ridgelines, also subjected to wet (NW) and dry (SW) climates. Incision is related to the age zonation of the island. Maximum incisions (Gran Canaria. Additional sources of uplift, such as gravitational unloading, lithospheric flexure induced by adjacent islands, and/or volcanic underplating, are required. The theoretical onset of lithospheric bulging beneath Gran Canaria, as exerted by Tenerife, promoted a broad westwards tilting of the former from 3.8–3.5 Ma ago. This overall tilting accelerated fluvial incision, erosional unloading, and, therefore, the sustained differential uplift on the Eastern slope of the island over its last erosional stage. Considering mean uplift rates for the East and West sectors, Eastern values (0.024 mm/yr) are double than those in the West (0.011 mm/yr), supporting the role of lithospheric flexure of adjacent islands as an additional source of uplift. Complex feedback between fluvial unloading, differential uplift, orographic effect, lithospheric flexure, and volcanic underplating, seems to control the geomorphological development of hot-spot volcanic islands, after the gravitational collapse of stratovolcanos during their rejuvenation stage.

The Cretaceous Okhotsk–Chukotka Volcanic Belt (NE Russia): Geology, geochronology, magma output rates, and implications on the genesis of silicic \\{LIPs\\}  

Science Journals Connector (OSTI)

The Cretaceous Okhotsk–Chukotka volcanic belt (OCVB) is a prominent subduction-related magmatic province, having the remarkably high proportion of silicic rocks (ca. 53% of the present-day crop area, and presumably over 70% of the total volcanic volume). Its estimated total extrusive volume ranges between 5.5 × 105 km3 (the most conservative estimate) and over 106 km3. This article presents a brief outline of the geology of OCVB, yet poorly described in international scientific literature, and results of a geochronological study on the northern part of the volcanic belt. On the base of new and published U–Pb and 40Ar/39Ar age determinations, a new chronological model is proposed. Our study indicates that the activity of the volcanic belt was highly discontinuous and comprised at least five main episodes at 106–98 Ma, 94–91 Ma, 89–87 Ma, 85.5–84 Ma, and 82–79 Ma. The new data allow a semi-quantitative estimate of the volcanic output rate for the observed part of the OCVB (area and volume approximately 105 km2 and 2.5 × 105 km3, respectively). The average extrusion rate for the entire lifetime of the volcanic belt ranges between 1.6 and 3.6 × 10? 5 km3yr? 1 km? 1, depending on the assumed average thickness of the volcanic pile; the optimal value is 2.6 × 10? 5 km3yr? 1 km? 1. Despite imprecise, such estimates infer the time-averaged volcanic productivity of the OCVB is similar to that of silicic \\{LIPs\\} and most active recent subduction-related volcanic areas of the Earth. However, the most extensive volcanic flare-ups at 89–87 and 85.5-84 Ma had higher rates of over 9.0 × 10? 5 km3yr? 1 km? 1. The main volumetric, temporal and compositional parameters of the OCVB are similar to those of silicic LIPs. This gives ground for discussion about the geodynamic setting of the latters, because the widely accepted definition of a LIP implies a strictly intraplate environment. Considering the genesis of the OCVB and other large provinces of silicic volcanism, we propose that residual thermal energy preserved in the continental crust after a previous major magmatic event may have been one of major reasons for high proportion of felsic rocks in a volcanic pile. In this scenario, underplating of mantle-derived basalts causes fast and extensive melting of still hot continental crust and generation of voluminous silicic magmas.

Established geophysical and geochemical techniques for geothermal exploration including gravity, major cations/anions and gas analysis will be combined with atypical implementations of additional geophysics (aeromagnetics) and geochemistry (CO2 flux, 14C measurements, helium isotopes and imaging spectroscopy). Importantly, the combination of detailed CO2 flux, 14C measurements and helium isotopes will provide the ability to directly map geothermal fluid upflow as expressed at the surface. Advantageously, the similar though active volcanic and hydrothermal systems on the east flanks of Kilauea have historically been the subject of both proposed geophysical surveys and some geochemistry; the Puna Geothermal Field (Puna) (operated by Puna Geothermal Venture [PGV], an Ormat subsidiary) will be used as a standard by which to compare both geophysical and geochemical results.

Factors controlling the morphology of monogenetic basaltic volcanoes: The Holocene volcanism of Gran Canaria (Canary Islands, Spain)  

Science Journals Connector (OSTI)

A detailed morphometric analysis was performed on the 24 Holocene eruptions of Gran Canaria, a nearly circular island located at the centre of the Canary Islands (Spain), developed as result of the eastward movement of the African plate over a mantle hotspot. Rigorous field work was carried out to generate a palaeogeomorphological reconstruction of the Holocene eruptions of Gran Canaria to obtain pre- and post-eruption digital terrain models (DTMs). These eruptions were of Strombolian monogenetic basaltic volcanism style. With respect to the cones, feeder fissures determine their location and some morphological features as crater openings which are usually perpendicular to the slope direction. In addition, the trade winds influence the final volcanic edifice shape and the extent of the pyroclastic sheet-like fall deposits. For the lava flows, the most significant controls are the eruption rate, affecting the maximum distance travelled, and the gully slope and shape that condition their flow path. Concerning volcanic hazard and risk assessment, the applied methodology has led to a better understanding of the recent eruptions and foresees the location and nature of future eruptions.

Plutonium aging  

SciTech Connect (OSTI)

The author describes the plutonium aging program at the Los Alamos National Laboratory. The aging of plutonium components in the US nuclear weapons stockpile has become a concern due to several events: the end of the cold war, the cessation of full scale underground nuclear testing as a result of the Comprehensive Test Ban Treaty (CTBT) and the closure of the Rocky Flats Plant--the site where the plutonium components were manufactured. As a result, service lifetimes for nuclear weapons have been lengthened. Dr. Olivas will present a brief primer on the metallurgy of plutonium, and will then describe the technical approach to ascertaining the long-term changes that may be attributable to self-radiation damage. Facilities and experimental techniques which are in use to study aging will be described. Some preliminary results will also be presented.

13 13 On Tenth Anniversary of NETL Program, Regional Partnerships Demonstrate Clear Path to CO2 Reduction What is a Greenhouse Gas? Why is it important? And how can we reduce it? When gases trap radiant heat from the sun in Earth's atmosphere, they are called greenhouse gases. There are many such gases, but carbon dioxide (CO2) is one of the most prevalent. CO2 is a part of everyday life on this planet. It is used by plants during photosynthesis, expelled into the atmosphere during a volcanic eruption, produced as the result of decaying organic matter, and emmited during the burning of fossils fuels and other industrial activities. However, just like everything else, too much CO2 can be bad. Greenhouse gas levels in the atmosphere have increased significantly above pre-industrial revolution levels and scientists are concerned that the rising atmospheric levels of various greenhouse gases could be a contributing factor to global climate change. So the question is: how can we reduce CO2 concentrations in the atmosphere?

Thyroid cancer incidence in relation to volcanic activity  

SciTech Connect (OSTI)

Environmental or genetic factors are sought to explain the high incidence of thyroid cancer in Iceland. At present, it is impossible to cite any environmental factor, particularly one related to the volcanic activity in the country, which could explain the high incidence of thyroid cancer in Iceland. However, the thyroid gland in Icelanders is very small due to the high intake of iodine from seafood. It is, therefore, easier for physicians to find thyroid tumors. Furthermore, genetic factors are very likely to be of great importance in the small, isolated island of Iceland.

Substation fire protection features  

SciTech Connect (OSTI)

This paper describes Commonwealth Edison`s (ComEd) approach to substation fire protection. Substation fires can have a major operational, financial, as well as political impact on a utility. The overall Company philosophy encompasses both active and passive fire protection features to provide prompt detection, notification, and confinement of fire and its by-products. Conservatively designed smoke detection systems and floor and wall penetration seals form the backbone of this strategy. The Company has implemented a program to install these features in new and existing substations. Thus far these measures have been successful in mitigating the consequences of substation fires.

Paleomagnetic and paleointensity study of Oligocene volcanic rocks from Chihuahua (northern Mexico)  

Science Journals Connector (OSTI)

A detailed rock-magnetic, paleomagnetic and paleointensity study was carried out on Oligocene volcanic formations from Chihuahua (northern Mexico) in order to obtain some decisive constraints for the tectonic evolution of the southern Cordilleran Orogenic Belt of North America and for the geomagnetic field strength during Oligocene time. Age of the volcanic units lies between 33 and 25 Ma according to available radiometric data. Rock-magnetic experiments reveal that remanence is carried in most cases by Ti-poor titanomagnetite, resulting of oxy-exsolution of original titanomagnetite during the initial flow cooling. Unblocking temperature spectra and relatively high coercivities point to ‘small’ pseudo-single domain magnetic grains for these (titano)magnetites. Single-component, linear demagnetization plots were observed in most cases. Nine sites yield reverse polarity magnetization, three are normally magnetized and one unit shows intermediate polarity magnetization. An evidence of strong lightning-produced magnetization overprint was detected for one site. Combining all paleomagnetic data currently available for northern Mexico, we obtained a well-defined Eocene–Oligocene mean paleomagnetic direction with I=48.5°, D=337.1°, k=20, ?95=6.8°, N=24, which deviates counterclockwise from the expected direction estimated from the North American apparent polar wander path. This suggests a vertical-axis tectonic counterclockwise rotation of about 16° relative to stable North America. Transition from Laramide compression to Basin and Range extension occurred during Oligocene, around 32–30 Ma. Tectonic rotation may then reflect east–northeast extension in the mid- to late-Cenozoic. Twenty-three samples were pre-selected for Thellier palaeointensity experiments because of their low viscosity index, stable remanent magnetization and reasonably reversible continuous thermomagnetic curves. Only 12 samples, coming from three individual basaltic lava flows, yielded reliable paleointensity estimates with the flow-mean virtual dipole moments (VDM) ranging from 3.96 to 4.65×1022 Am2. Combination of Mexican data with the available comparable quality Oligocene paleointensity results yield a mean VDM of 4×1022 Am2, which is comparable or slightly higher than the mean \\{VDMs\\} calculated for the Mesozoic low field period, but significantly lower than present day value. This low intensity may correlate with the relatively high paleosecular variation rate invoked around 30 Ma by several authors.

Salient Salient Biological Features, Systematics, and Genetic Variation of Populus Gancho T. Slavov and Peter Zhelev Abstract The genus Populus includes morphologically diverse species of decid- uous, relatively short-lived, and fast-growing trees. Most species have wide ranges of distribution but tend to occur primarily in riparian or mountainous habitats. Trees from this genus are typically dioecious, flower before leaf emer- gence, and produce large amounts of wind-dispersed pollen or seeds. Seedlings are drought- and shade-intolerant, and their establishment depends on distur- bance and high soil moisture. Asexual reproduction is common and occurs via root sprouting and/or rooting of shoots. Fossil records suggest that the genus appeared in the late Paleocene or early Eocene (i.e., 50-60 million years BP). According to one commonly used classification, the genus is comprised

Supai salt karst features: Holbrook Basin, Arizona  

SciTech Connect (OSTI)

More than 300 sinkholes, fissures, depressions, and other collapse features occur along a 70 km (45 mi) dissolution front of the Permian Supai Formation, dipping northward into the Holbrook Basin, also called the Supai Salt Basin. The dissolution front is essentially coincident with the so-called Holbrook Anticline showing local dip reversal; rather than being of tectonic origin, this feature is likely a subsidence-induced monoclinal flexure caused by the northward migrating dissolution front. Three major areas are identified with distinctive attributes: (1) The Sinks, 10 km WNW of Snowflake, containing some 200 sinkholes up to 200 m diameter and 50 m depth, and joint controlled fissures and fissure-sinks; (2) Dry Lake Valley and contiguous areas containing large collapse fissures and sinkholes in jointed Coconino sandstone, some of which drained more than 50 acre-feet ({approximately}6 {times} 10{sup 4} m{sup 3}) of water overnight; and (3) the McCauley Sinks, a localized group of about 40 sinkholes 15 km SE of Winslow along Chevelon Creek, some showing essentially rectangular jointing in the surficial Coconino Formation. Similar salt karst features also occur between these three major areas. The range of features in Supai salt are distinctive, yet similar to those in other evaporate basins. The wide variety of dissolution/collapse features range in development from incipient surface expression to mature and old age. The features began forming at least by Pliocene time and continue to the present, with recent changes reportedly observed and verified on airphotos with 20 year repetition. The evaporate sequence along interstate transportation routes creates a strategic location for underground LPG storage in leached caverns. The existing 11 cavern field at Adamana is safely located about 25 miles away from the dissolution front, but further expansion initiatives will require thorough engineering evaluation.

Growth, destruction and facies architecture of effusive and explosive volcanics in the Miocene Shama basin, southwest of Saudi Arabia: Subaqueous–subaerial volcanism in a lacustrine setting  

Science Journals Connector (OSTI)

Abstract The Harrat Shama Volcanic Basin (HSVB) is a part of a small, well-exposed intra-continental extensional basin that formed during the opening of the Red Sea, containing 5 km of Miocene bimodal volcanics and volcaniclastic rocks. The Shama basin accumulated a thick fluvio-lacustrine fill in which two distinct volcanic sequences and their deposits can overlap with each other. In addition, complete facies architectures of the Shama volcanics have been recognized providing a complex mixed siliciclastic and volcaniclastic basin infill in the respective basin where volcanism took place. The lower sequence is composed of hyaloclastites, zeolite-bearing bedded tuffs, and bedded accretionary-lapilli-tuffs and an upper sequence, is made up of pumiceous lapilli-tuffs and peperitic breccias capped by basaltic lava flows. The former is interpreted to have been dominated by discrete, phreatomagmatic fall deposits, which are attributed to an overall high eruption rate in a lacustrine setting, followed by a dominantly subaerial pumiceous lapilli tuff deposits and volcaniclastic sediments sited in the upper part of the basin with paleosols and/or fluvial deposits in between the two sequences. These deposits could be related to polygenetic volcanoes and tectonic structures, such as faults and rift-zones. These two sequences display a complex succession of effusive and explosive volcanisms and their reworked deposits, with abundant evidences of magma–water interaction such as peperites for non-explosive magma–water interaction with the lacustrine water-saturated sediment and standing water body in a lake environment. The difference eruption dynamics and fragmentation mechanisms between the two sequences reflect progressive environmental changes from subaqueous or watery to subaerial or dry. Fluvial erosion and deposition completed the evolution of the emergent marginal part of the Shama basin. The Shama basin then experienced volcano growth and degradation that formed the two sequences; NW-SE-trending basement faulting triggered multiple flank collapses and volcanic debris avalanches, and voluminous pumiceous lapilli-tuff eruptions produced a caldera (upper sequence). Lacustrine conditions persisted during the destruction and post-destruction stages of the volcano's evolution, as evidenced by magma–water interactions. Shama basin is a small-volume volcano, similar to tuff rings; however, its magma compositions, complex eruption styles, and inter-eruptive breaks suggest, that it closely resembles a volcanic architecture commonly associated with large, composite volcanoes. The main cause of such complex eruptive behavior resides in the stratigraphic, structural, and hydrogeological characteristics of the substrate above which the volcanoes were emplaced, rather than on the compositional characteristics of the erupting magma, which do not show significant variation among the different deposits.

Geologic evolution of the Jemez Mountains and their potential for future volcanic activity  

SciTech Connect (OSTI)

Geophysical and geochemical data and the geologic history of the Rio Grande rift and the vicinity of the Jemez Mountains are summarized to determine the probability of future volcanic activity in the Los Alamos, New Mexico area. The apparent cyclic nature of volcanism in the Jemez Mountains may be related to intermittent thermal inputs into the volcanic system beneath the region. The Jemez lineament, an alignment of late Cenozoic volcanic centers that crosses the rift near Los Alamos, has played an important role in the volcanic evolution of the Jemez Mountains. Geophysical data suggest that there is no active shallow magma body beneath the Valles caldera, though magma probably exists at about 15 km beneath this portion of the rift. The rate of volcanism in the Jemez Mountains during the last 10 million years has been 5 x 10/sup -9//km/sup 2//y. Lava or ash flows overriding Laboratory radioactive waste disposal sites would have little potential to release radionuclides to the environment. The probability of a new volcano intruding close enough to a radioactive waste disposal site to effect radionuclide release is 2 x 10/sup -7//y.

Uranium mineralization in fluorine-enriched volcanic rocks  

SciTech Connect (OSTI)

Several uranium and other lithophile element deposits are located within or adjacent to small middle to late Cenozoic, fluorine-rich rhyolitic dome complexes. Examples studied include Spor Mountain, Utah (Be-U-F), the Honeycomb Hills, Utah (Be-U), the Wah Wah Mountains, Utah (U-F), and the Black Range-Sierra Cuchillo, New Mexico (Sn-Be-W-F). The formation of these and similar deposits begins with the emplacement of a rhyolitic magma, enriched in lithophile metals and complexing fluorine, that rises to a shallow crustal level, where its roof zone may become further enriched in volatiles and the ore elements. During initial explosive volcanic activity, aprons of lithicrich tuffs are erupted around the vents. These early pyroclastic deposits commonly host the mineralization, due to their initial enrichment in the lithophile elements, their permeability, and the reactivity of their foreign lithic inclusions (particularly carbonate rocks). The pyroclastics are capped and preserved by thick topaz rhyolite domes and flows that can serve as a source of heat and of additional quantities of ore elements. Devitrification, vapor-phase crystallization, or fumarolic alteration may free the ore elements from the glassy matrix and place them in a form readily leached by percolating meteoric waters. Heat from the rhyolitic sheets drives such waters through the system, generally into and up the vents and out through the early tuffs. Secondary alteration zones (K-feldspar, sericite, silica, clays, fluorite, carbonate, and zeolites) and economic mineral concentrations may form in response to this low temperature (less than 200 C) circulation. After cooling, meteoric water continues to migrate through the system, modifying the distribution and concentration of the ore elements (especially uranium).

Prevalence rates and clinical implications of bipolar disorder “with mixed features” as defined by DSM-5  

Science Journals Connector (OSTI)

AbstractBackground We investigated the increase in the prevalence of bipolar disorder with mixed features following the replacement of DSM-IV-TR criteria with DSM-5 criteria. Additionally, we examined the clinical implications of the use of “with mixed features” as a specifier with bipolar disorder. Method We retrospectively reviewed medical charts from 2003 to 2013. A total of 331 patients diagnosed with bipolar disorder using the DSM-IV TR were enrolled and categorized into four groups: manic/hypomanic with mixed features, manic/hypomanic without mixed features, depressed with mixed features, and depressed without mixed features. These classifications were made in accordance with the DSM-5 definition of bipolar disorder “with mixed features.” Changes in the prevalence, demographic and clinical characteristics were compared among the groups. Results The prevalence rates of mixed features were significantly different when using the DSM-5 criteria vs. the DSM-IV-TR criteria. Patients with mixed features had a younger age of onset, younger age at hospitalization, more frequent hospitalizations for mixed episodes, and greater suicide risk compared with patients without mixed features. Limitations Retrospective study may have resulted in under diagnosis of mixed states. Conclusions An approximately three-fold greater risk for mixed features was observed in patients with bipolar disorder when using the DSM-5 criteria than when using the DSM-IV-TR criteria. The additional patients may represent patients with sub-syndromal mixed features and could indicate that patients with mixed features are underdiagnosed.

Determining age of whales  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Determining age of whales Determining age of whales Name: Bruce W Walkey Age: N/A Location: N/A Country: N/A Date: N/A Question: While browsing through the Internet, I came upon a question by two fifth grade students. Their question got me thinking and now I pose it to you. How can you determine the age of whales? Since they are mammals, can the methods that are used on humans be used on whales? What are some tests that can be done on bones or tissues to determine age? Looking forward to your reply. Replies: Although it is difficult to determine the age of whales (unless they are born in captivity and we know their birth date), several methods have been commonly used: 1) (if female) the examination of the ovaries 2) Examination of the ridges on baleen, which are not uniform in size and analogous to tree rings. The problem with this is that baleen wears away over time. 3) Studying layers of ossification in an ear bone is probably the most accurate method of aging, since internal bones don't wear away. The biggest problem with aging methods is that they usually require that you are dissecting the animal, and often, we would like a method of aging for live active animals. The best we can do here is to compare the size and markings of whales of known age to those found in the wild. Great question!

Entangled topological features of light  

E-Print Network [OSTI]

We report the entanglement of topological features, namely, isolated, linked optical vortex loops in the light from spontaneous parametric down-conversion (SPDC). In three dimensions, optical vortices are lines of phase singularity and vortices of energy flow which percolate through all optical fields. This example of entanglement is between features that extend over macroscopic and finite volumes, furthermore, topological features are robust to perturbation . The entanglement of photons in complex three-dimensional(3D) topological states suggests the possibility of entanglement of similar structures in other quantum systems describable by complex scalar functions, such as superconductors, superfluids and Bose-Einstein condensates.

Speech understanding and aging  

Science Journals Connector (OSTI)

The increasing age of the population forecasts a corresponding increase in the number of people suffering from hearing loss and who therefore have difficulty with speech communication. This article prepared by the Working Group on Speech Understanding and Aging for the Committee on Hearing Bioacoustics and Biomechanics discusses a number of the factors that act on the elderly listener’s ability to understand speech including physiological aging changes in cognitive ability noisy signals and sensory aids. Both sensory and perceptual processes are considered.

Comparative analysis of core drilling and rotary drilling in volcanic terrane  

SciTech Connect (OSTI)

Initially, the goal of this report is to compare and contrast penetration rates of rotary-mud drilling and core drilling in young volcanic terranes. It is widely recognized that areas containing an abundance of recent volcanic rocks are excellent targets for geothermal resources. Exploration programs depend heavily upon reliable subsurface information, because surface geophysical methods may be ineffective, inconclusive, or both. Past exploration drilling programs have mainly relied upon rotary-mud rigs for virtually all drilling activity. Core-drilling became popular several years ago, because it could deal effectively with two major problems encountered in young volcanic terranes: very hard, abrasive rock and extreme difficulty in controlling loss of circulation. In addition to overcoming these difficulties, core-drilling produced subsurface samples (core) that defined lithostratigraphy, structure and fractures far better than drill-chips. It seemed that the only negative aspect of core drilling was cost. The cost-per-foot may be two to three times higher than an ''initial quote'' for rotary drilling. In addition, penetration rates for comparable rock-types are often much lower for coring operations. This report also seeks to identify the extent of wireline core drilling (core-drilling using wireline retrieval) as a geothermal exploration tool. 25 refs., 21 figs., 13 tabs.

Nuclear age thinking  

SciTech Connect (OSTI)

According to the practicalist school, thinking emerges from activity and each human practice is giving food to its own distinctive kinds of perception, conduct, and perspective of the world. The author, while studying and describing developments after the commencement of the nuclear age in many fields of human behavior and knowledge, including the social sciences, particularly psychology and international politics, became an adherent to the practicalist philosophy when he perceived new relevant thoughts coming to his mind at the same time. Indeed writing is a learning experience. He has, therefore, systematically included these thoughts in the following pages and synoptically characterized them in the title: Nuclear Age Thinking. He considers this kind of thinking as automatic, conscious activity which is gradually influencing our choices and decisions. The author has reservations as regards Albert Einstein's saying that the unleashed power of the atom changed everything save our modes of thinking, because the uncontrollability of nuclear energy is apparently in the subconscious of mankind nowadays, influencing the development of a new mode of thinking, and that is the nuclear age thinking which is the subject of this book. Nuclear age thinking drives from the collective fear of extinction of life on earth due to this new power at man's disposal, and it is not only limited to the change in the conventional meaning of the words war and peace.

40Ar/39Ar ages from Fra Mauro  

Science Journals Connector (OSTI)

High temperature40Ar/39Ar ages have been determined for four rock fragments selected from coarse fines returned from Fra Mauro. Three are fragmental rocks in varying stages of recrystallization and the fourth is crystalline with a gabbro mineralogy, relatively devoid of shock features. All of the fragments have a common age of 3.75 ± 0.15 × 109 yr. The ages suggest intense activity, possibly the Imbrium event, at 3.75 × 109 yr ago which has precluded the identification of more primitive material.

Science Journals Connector (OSTI)

Four sites have been drilled in the submarine volcaniclastic apron of the volcanic island of Gran Canaria during the ODP Leg 157. The volcaniclastic submarine apron reflects the volcanological evolution of the island. The main volcanic phases are recorded in the sedimentation by an important contemporaneous clastic influx on the apron. However, periods of volcanic quiescence are characterized by very weak sedimentation rates. Consequently, it is possible to establish a volcanostratigraphy from the sedimentary record of the apron.

Geochronological, geochemical and Sr–Nd–Hf isotopic constraints on the origin of the Cretaceous intraplate volcanism in West Qinling, Central China: Implications for asthenosphere–lithosphere interaction  

Science Journals Connector (OSTI)

Abstract This paper reports new zircon LA-ICP-MS \\{UPb\\} age and Lu-Hf isotopes, laser-fusion 40Ar/39Ar age, mineral chemistry, bulk-rock major and trace element, and SrNd isotope data from intraplate volcanic rocks in the Duofuntun Area, West Qinling. It was dated at 105.8 ± 0.9 Ma (UPb Zircon) and 103 ± 2 Ma (matrix glass laser-fusion 40Ar/39Ar dating). The Duofuntun Volcanic Rocks (DVR) are dominantly composed of alkali basalts with minor basanites and basaltic andesites. Some evolved samples of the DVR underwent a variable fractionation of olivine, clinopyroxene, plagioclase, FeTi oxide, Cr-rich spinel and apatite. Chondrite-normalized rare earth element and primitive mantle-normalized trace element patterns of the DVR remarkably resemble those of oceanic island basalts (OIB). Nearly all the alkali basalts show positive Nb, Ta and Ti anomalies and negative Rb, Th and P anomalies, whereas basanites do not display positive Ti anomalies. Nearly all the samples show marked negative Rb and K anomalies relative to their neighbouring elements on a primitive mantle normalized trace element diagram. 87Sr/86Sr(i) and 143Nd/144Nd(i) ratios for all the mafic samples also show an OIB affinity, covering a range of 0.703264–0.705032 and 0.512718–0.512873, respectively. Several lines of evidence indicate that both garnet and amphibole play a key role for the genesis of the DVR. The melt segregation PT conditions in the source region, around 1371 °C at 1.98–3.25 GPa, combined with trace element collectively suggest a polybaric melting process during the formation of the DVR. The non-modal batch partial melting modelling result indicates the DVR were generated by small-degree polybaric partial melting of amphibole-bearing spinel peridotites (ca. 4%) and amphibole-bearing garnet peridotites (ca. 0.7%). We suggest the DVR were not formed in a plume. Rather, they originated by the interaction between the upwelling asthenosphere, which might provide both materials and heat flux, and hydrous mineral-bearing (amphibole) lithosphere during lithospheric extension.

Age of Goose Rock Conglomerate, Wheele and Grant Counties, north-central Oregon  

SciTech Connect (OSTI)

A reconstruction of the geologic history and synthesis of the tectonic history of the Blue Mountains and Columbia Basin require that they know the age of key outcrops. The geological record in this entire area has been largely hidden by a thick blanket of Tertiary volcanic rocks. Only a few erosional inliers are available from which to interpret the pre-volcanic tectonic and sedimentation history. The Goose Rock Inlier, exposed along the John Day River in the Butler basin and Turtle Cove, is one such important outcrop. These exposures, consisting of a few hundred feet of fluvial sandstones and conglomerates, informally called the Goose Rock Conglomerate have received only limited attention from previous workers. Estimates of this unit's age range from Early Cretaceous to early Tertiary, on the basis of lithologic similarities with other named and unnamed formations in the area. The terrestrial nature of these strata and the apparent lack of fossils cause considerable difficulty in correlation with other Cretaceous sequences, which are largely marine. In the absence of scarcity of other fossils, palynology offers a unique alternative for making biochronological and paleoenvironmental interpretations.

TECTONIC VERSUS VOLCANIC ORIGIN OF THE SUMMIT DEPRESSION AT MEDICINE LAKE VOLCANO, CALIFORNIA  

SciTech Connect (OSTI)

Medicine Lake Volcano is a Quaternary shield volcano located in a tectonically complex and active zone at the transition between the Basin and Range Province and the Cascade Range of the Pacific Province. The volcano is topped by a 7x12 km elliptical depression surrounded by a discontinuous constructional ring of basaltic to rhyolitic lava flows. This thesis explores the possibility that the depression may have formed due to regional extension (rift basin) or dextral shear (pull-apart basin) rather than through caldera collapse and examines the relationship between regional tectonics and localized volcanism. Existing data consisting of temperature and magnetotelluric surveys, alteration mineral studies, and core logging were compiled and supplemented with additional core logging, field observations, and fault striae studies in paleomagnetically oriented core samples. These results were then synthesized with regional fault data from existing maps and databases. Faulting patterns near the caldera, extension directions derived from fault striae P and T axes, and three-dimensional temperature and alteration mineral models are consistent with slip across arcuate ring faults related to magma chamber deflation during flank eruptions and/or a pyroclastic eruption at about 180 ka. These results are not consistent with a rift or pull-apart basin. Limited subsidence can be attributed to the relatively small volume of ash-flow tuff released by the only known major pyroclastic eruption and is inconsistent with the observed topographic relief. The additional relief can be explained by constructional volcanism.

Tectonic versus volcanic origin of the summit depression at Medicine Lake Volcano, California  

SciTech Connect (OSTI)

Medicine Lake Volcano is a Quaternary shield volcano located in a tectonically complex and active zone at the transition between the Basin and Range Province and the Cascade Range of the Pacific Province. The volcano is topped by a 7x12 km elliptical depression surrounded by a discontinuous constructional ring of basaltic to rhyolitic lava flows. This thesis explores the possibility that the depression may have formed due to regional extension (rift basin) or dextral shear (pull-apart basin) rather than through caldera collapse and examines the relationship between regional tectonics and localized volcanism. Existing data consisting of temperature and magnetotelluric surveys, alteration mineral studies, and core logging were compiled and supplemented with additional core logging, field observations, and fault striae studies in paleomagnetically oriented core samples. These results were then synthesized with regional fault data from existing maps and databases. Faulting patterns near the caldera, extension directions derived from fault striae P and T axes, and three-dimensional temperature and alteration mineral models are consistent with slip across arcuate ring faults related to magma chamber deflation during flank eruptions and/or a pyroclastic eruption at about 180 ka. These results are not consistent with a rift or pull-apart basin. Limited subsidence can be attributed to the relatively small volume of ash-flow tuff released by the only known major pyroclastic eruption and is inconsistent with the observed topographic relief. The additional relief can be explained by constructional volcanism. Striae from unoriented and oriented core, augmented by striae measurements in outcrop suggest that Walker Lane dextral shear, which can be reasonably projected from the southeast, has probably propagated into the Medicine Lake area. Most volcanic vents across Medicine Lake Volcano strike north-south, suggesting they are controlled by crustal weakness related to Basin and Range extension. Interaction of dextral shear, Basin and Range extension, and the zone of crustal weakness expressed as the Mount Shasta-Medicine Lake volcanic highland controlled the location and initiation of Medicine Lake Volcano at about 500 ka.

Volcanic ash in feed coal and its influence on coal combustion products  

SciTech Connect (OSTI)

The US Geological Survey and the University of Kentucky Center for Applied Energy Research are collaborating with an Indiana Utility to determine the physical and chemical properties of feed coal and coal combustion products (CCPs) from a coal-fired power plant. The plant utilizes a low-sulfur (.23--.47 weight percent S) coal from the Powder River Basin, Wyoming. Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) analysis of feed coal samples identified two mineral suites. A primary suite (not authigenic) consisting of quartz (detrital and volcanic beta-form grains), biotite, and minor zircon and a secondary authigenic mineral suite containing calcite, alumino-phosphates (crandallite and gorceixite), kaolinite, quartz, anatase, barite, and pyrite. The authigenic minerals are attributed to air-fall and reworked volcanic ash that was deposited in peat-forming mires. The Powder River Basin feed coals contain higher amounts of Ba, Ca, Mg, Na, Sr, and P compared to other analyzed eastern coals. These elements are associated with alumino-phosphate, biotite, calcite, and clay minerals. The element associations are indicative of coal that incorporated volcanic ash during deposition. XRD analysis of CCPs revealed a predominance of glass, perovskite, lime, gehlenite, quartz, and phosphates with minor amounts of periclase, anhydrite, hematite, and spinel group minerals in the fly ash; and quartz, plagioclase (albite and anorthite), pyroxene (augite and fassaite), rhodonite, and akermanite in the bottom ash. Microprobe and SEM analysis of fly ash samples revealed quartz, zircon, monazite, euhedral laths of corundum with merrillite, hematite, dendritic spinels/ferrites, and rounded grains of wollastonite with periclase. The abundant Ca and Mg mineral phases in the fly ashes are related to the presence of carbonate, clay, and phosphate minerals in the feed coal. The Ca- and Mg-rich mineral phases in the CCPs can be attributed to volcanic minerals deposited in the peat-forming mire. Dissolution and alteration of these minerals occurred either in the peat-forming sate or during coalification/diagenesis contributing to the authigenic mineral suite. Additionally, detrital mineral input and epigenetic ground-water flow may have affected the geochemistry of the feed coal.

Ice age paleotopography  

SciTech Connect (OSTI)

A gravitationally self-consistent theory of postglacial relative sea level change is used to infer the variation of surface ice and water cover since the Last Glacial Maximum (LGM). The results show that LGM ice volume was approximately 35 percent lower than suggested by the CLIMAP reconstruction and the maximum heights of the main Laurentian and Fennoscandian ice complexes are inferred to have been commensurately lower with respect to sea level. Use of these Ice Age boundary conditions in atmospheric general circulation models will yield climates that differ significantly from those previously inferred on the basis of the CLIMAP data set.

Feature Tracking Using Reeb Graphs  

SciTech Connect (OSTI)

Tracking features and exploring their temporal dynamics can aid scientists in identifying interesting time intervals in a simulation and serve as basis for performing quantitative analyses of temporal phenomena. In this paper, we develop a novel approach for tracking subsets of isosurfaces, such as burning regions in simulated flames, which are defined as areas of high fuel consumption on a temperature isosurface. Tracking such regions as they merge and split over time can provide important insights into the impact of turbulence on the combustion process. However, the convoluted nature of the temperature isosurface and its rapid movement make this analysis particularly challenging. Our approach tracks burning regions by extracting a temperature isovolume from the four-dimensional space-time temperature field. It then obtains isosurfaces for the original simulation time steps and labels individual connected 'burning' regions based on the local fuel consumption value. Based on this information, a boundary surface between burning and non-burning regions is constructed. The Reeb graph of this boundary surface is the tracking graph for burning regions.

Detecting volcanic resurfacing of heavily cratered terrain: Flooding simulations on the Moon using Lunar Orbiter Laser Altimeter (LOLA) data  

Science Journals Connector (OSTI)

Abstract Early extrusive volcanism from mantle melting marks the transition from primary to secondary crust formation. Detection of secondary crust is often obscured by the high impact flux early in solar system history. To recognize the relationship between heavily cratered terrain and volcanic resurfacing, this study documents how volcanic resurfacing alters the impact cratering record and models the thickness, area, and volume of volcanic flood deposits. Lunar Orbiter Laser Altimeter (LOLA) data are used to analyze three different regions of the lunar highlands: the Hertzsprung basin; a farside heavily cratered region; and the central highlands. Lunar mare emplacement style is assumed to be similar to that of terrestrial flood basalts, involving large volumes of material extruded from dike-fed fissures over relatively short periods of time. Thus, each region was flooded at 0.5 km elevation intervals to simulate such volcanic flooding and to assess areal patterns, thickness, volumes, and emplacement history. These simulations show three primary stages of volcanic flooding: (1) Initial flooding is largely confined to individual craters and deposits are thick and localized; (2) basalt flows breach crater rim crests and are emplaced laterally between larger craters as thin widespread deposits; and (3) lateral spreading decreases in response to regional topographic variations and the deposits thicken and bury intermediate-sized and larger craters. Application of these techniques to the South Pole-Aitken basin shows that emplacement of ?1?2 km of cryptomaria can potentially explain the paucity of craters 20–64 km in diameter on the floor of the basin relative to the distribution in the surrounding highlands.

Patch layout generation by detecting feature networks  

Science Journals Connector (OSTI)

Abstract The patch layout of 3D surfaces reveals the high-level geometric and topological structures. In this paper, we study the patch layout computation by detecting and enclosing feature loops on surfaces. We present a hybrid framework which combines several key ingredients, including feature detection, feature filtering, feature curve extension, patch subdivision and boundary smoothing. Our framework is able to compute patch layouts through concave features as previous approaches, but also able to generate nice layouts through smoothing regions. We demonstrate the effectiveness of our framework by comparing with the state-of-the-art methods.

Special Feature: Quantum Measurement Standards  

Science Journals Connector (OSTI)

This special feature is intended to present a comprehensive review of the present state and novel trends in the field of quantum measurement standards. Most of the present metrological research is concentrated on establishing and strengthening the links between the units and fundamental constants. This will be demonstrated in the nine articles in this feature. The first four articles are devoted to time, frequency and length metrology. They describe quantum standards that are used or intended to be used for the realization of the SI base units of time and length, the second and the metre. The two units are related to each other by an adopted fixed value of the speed of light in vacuum and the second is at present defined by the energy difference (frequency) of a hyperfine transition in the ground state of caesium. The special feature starts with the discussion of caesium atomic clocks as direct realizations of the second and as a basis for other standards (e.g. the Josephson voltage quantum standard). Whereas Cs atomic clocks still provide us with the most accurate realization of the second, optical frequency standards based on cold trapped ions or cold atoms may eventually lead us to even lower uncertainty levels and may replace the present definition of the second by an optical transition. This situation is described in the contribution on optical frequency standards based on trapped single ions. Since optical frequency standards are also needed as wavelength standards in length metrology, the third contribution reviews the definition of the metre. It describes the different methods of realization, in particular by optical frequency standards including standards based on cold atoms. The use of optical frequency standards in time and length metrology requires the precise knowledge of their frequencies. Methods of optical frequency measurements based on various methods—including frequency comb generators—are discussed in the fourth article. Turning to the electric units, the discovery of two macroscopic quantum effects, the Josephson effect—discovered in the early sixties—and the quantum Hall effect—discovered in 1980—allowed the linking of electric units to fundamental constants. By use of the Josephson effect quantized voltage values are realized as multiples of the product of a certain frequency and of the superconducting flux quantum (h/2e). Quantized resistance values are realized with the quantum Hall effect as submultiples of h/e2, where this fundamental constant can also be interpreted as the quotient of the flux quantum of a normal conductor and the elementary charge. The metrological application became much easier by making use of the possibility of designing and manufacturing appropriate samples with microelectronic techniques. Since 1990 all calibrations of voltages or resistances worldwide have been based on these two quantum effects. Relative uncertainties of the order of 10-9 are obtained. International comparisons have proved that the calibration results in different laboratories also agree within relative uncertainties of a few parts in 109. Great attempts have also been made to realize a current quantum standard by counting single electrons. The Josephson effect and its application are described by Kohlmann and co-workers. The quantum Hall effect is only briefly described in this issue of Measurement Science and Technology since a comprehensive review article by Jeckelmann and Jeanneret appeared recently [1]. The unit of mass, the kilogram, is the only base unit in the SI that is derived from an artefact. Therefore one major task of today's metrological research is the linking of the unit of mass to a fundamental constant. There are two rival attempts: the comparison of mechanical and electrical power using the watt-balance and the counting of a large number of identical particles, like atoms or ions. The watt balance was pioneered by B Kibble. This experiment consists of two parts. A balance in equilibrium is opposed to a gravitational force and to a force on a coil fed by a current and opp

ATMOSPHERIC DISPERSAL AND DEPOSITION OF TEPHRA FROM A POTENTIAL VOLCANIC ERUPTION AT YUCCA MOUNTAIN, NEVADA  

SciTech Connect (OSTI)

The purpose of this model report is to provide documentation of the conceptual and mathematical model (Ashplume) for atmospheric dispersal and subsequent deposition of ash on the land surface from a potential volcanic eruption at Yucca Mountain, Nevada. This report also documents the ash (tephra) redistribution conceptual model. These aspects of volcanism-related dose calculation are described in the context of the entire igneous disruptive events conceptual model in ''Characterize Framework for Igneous Activity'' (BSC 2004 [DIRS 169989], Section 6.1.1). The Ashplume conceptual model accounts for incorporation and entrainment of waste fuel particles associated with a hypothetical volcanic eruption through the Yucca Mountain repository and downwind transport of contaminated tephra. The Ashplume mathematical model describes the conceptual model in mathematical terms to allow for prediction of radioactive waste/ash deposition on the ground surface given that the hypothetical eruptive event occurs. This model report also describes the conceptual model for tephra redistribution from a basaltic cinder cone. Sensitivity analyses and model validation activities for the ash dispersal and redistribution models are also presented. Analyses documented in this model report update the previous documentation of the Ashplume mathematical model and its application to the Total System Performance Assessment (TSPA) for the License Application (TSPA-LA) igneous scenarios. This model report also documents the redistribution model product outputs based on analyses to support the conceptual model. In this report, ''Ashplume'' is used when referring to the atmospheric dispersal model and ''ASHPLUME'' is used when referencing the code of that model. Two analysis and model reports provide direct inputs to this model report, namely ''Characterize Eruptive Processes at Yucca Mountain, Nevada and Number of Waste Packages Hit by Igneous Intrusion''. This model report provides direct inputs to the TSPA, which uses the ASHPLUME software described and used in this model report. Thus, ASHPLUME software inputs are inputs to this model report for ASHPLUME runs in this model report. However, ASHPLUME software inputs are outputs of this model report for ASHPLUME runs by TSPA.

Improving clay content measurement in oxidic and volcanic ash soils of Hawaii by increasing dispersant concentration and ultrasonic energy levels  

Science Journals Connector (OSTI)

Abstract Quantifying clay content is a fundamental step in predicting and managing soil behaviors such as nutrient and water retention. However, clay measurements are underestimated when using standard methods of dispersion in soils rich in oxides and volcanic ash-derived non-crystalline minerals. Increasing levels of the chemical dispersant and ultrasonic energy are two simple techniques found to increase dispersion and clay measurements in temperate soils, but their effects are less known for oxidic and volcanic ash soils. In this study we investigated the effects of increasing dispersion concentration and ultrasonic energy on clay measurements for a range of oxidic and volcanic ash soils from Hawaii. While doubling and tripling the standard sodium hexametaphosphate concentration of 0.441 g L? 1 did not increase estimates of clay content, increasing levels of ultrasonic energy up to 1600 J mL? 1 significantly increased measured clay content for all oxide and volcanic ash soils. The response to ultrasonication was dependent on soil carbon, oxide content, and surface charge, with more energy needed to disperse soils higher in carbon, oxides, and positive charge. Scanning electron microscopy revealed damage to the sand fraction in some soils when ultrasonicated, but the extent of this damage was viewed as negligible. Porous sand-sized particles resembling pumice grains were also observed in some soils, suggesting that conventional particle size analysis and clay interpretations may not adequately describe surface related behaviors.

If the existence of cyclotron features seems now to be generally accepted the situation for the other features reported around 400?500 keV is not completely clarified. The presence of such features is discussed. Moreover some aspects of the high and low energy variations in the GRB and on the characteristics of their total spectrum are also reviewed. Finally future missions which might have a great impact in the GRB spectral analysis will be shortly considered.

Aging and functional brain networks  

SciTech Connect (OSTI)

Aging is associated with changes in human brain anatomy and function and cognitive decline. Recent studies suggest the aging decline of major functional connectivity hubs in the 'default-mode' network (DMN). Aging effects on other networks, however, are largely unknown. We hypothesized that aging would be associated with a decline of short- and long-range functional connectivity density (FCD) hubs in the DMN. To test this hypothesis, we evaluated resting-state data sets corresponding to 913 healthy subjects from a public magnetic resonance imaging database using functional connectivity density mapping (FCDM), a voxelwise and data-driven approach, together with parallel computing. Aging was associated with pronounced long-range FCD decreases in DMN and dorsal attention network (DAN) and with increases in somatosensory and subcortical networks. Aging effects in these networks were stronger for long-range than for short-range FCD and were also detected at the level of the main functional hubs. Females had higher short- and long-range FCD in DMN and lower FCD in the somatosensory network than males, but the gender by age interaction effects were not significant for any of the networks or hubs. These findings suggest that long-range connections may be more vulnerable to aging effects than short-range connections and that, in addition to the DMN, the DAN is also sensitive to aging effects, which could underlie the deterioration of attention processes that occurs with aging.

Long-term desorption behavior of uranium and neptunium in heterogeneous volcanic tuff materials /  

SciTech Connect (OSTI)

Uranium and neptunium desorption were studied in long-term laboratory experiments using four well-characterized volcanic tuff cores collected from southeast of Yucca Mountain, Nevada. The objectives of the experiments were to 1. Demonstrate a methodology aimed at characterizing distributions of sorption parameters (attributes of multiple sorption sites) that can be applied to moderately-sorbing species in heterogeneous systems to provide more realistic reactive transport parameters and a more realistic approach to modeling transport in heterogeneous systems. 2. Focus on uranium and neptunium because of their high solubility, relatively weak sorption, and high contributions to predicted dose in Yucca Mountain performance assessments. Also, uranium is a contaminant of concern at many DOE legacy sites and uranium mining sites.

Relative Ages of Globular Clusters  

E-Print Network [OSTI]

Ages of extragalactic globular clusters can provide valuable insights into the formation and evolution of galaxies. In this contribution the photometric methods of age dating old globular cluster systems are summarised. The spectroscopic approach is reviewed with an emphasis of the right choice of age diagnostics. We present a new method of quantifying the relatively best age-sensitive spectroscopic index given the quality of a data set and a certain theoretical stellar synthesis model. The relatively best diagnostic plot is constructed from the set of Lick indices and used to age date globular clusters in several early-type galaxies which are part of a large spectroscopic survey of extragalactic globular cluster systems. We find that, independently of host galaxy, metal-poor ([Fe/H] 8 Gyr) and coeval. Metal-rich clusters show a wide range of ages from ~15 down to a few Gyr.

Nuclear plant-aging research on reactor protection systems  

SciTech Connect (OSTI)

This report presents the rsults of a review of the Reactor Trip System (RTS) and the Engineered Safety Feature Actuating System (ESFAS) operating experiences reported in Licensee Event Reports (LER)s, the Nuclear Power Experience data base, Nuclear Plant Reliability Data System, and plant maintenance records. Our purpose is to evaluate the potential significance of aging, including cycling, trips, and testing as contributors to degradation of the RTS and ESFAS. Tables are presented that show the percentage of events for RTS and ESFAS classified by cause, components, and subcomponents for each of the Nuclear Steam Supply System vendors. A representative Babcock and Wilcox plant was selected for detailed study. The US Nuclear Regulatory Commission's Nuclear Plant Aging Research guidelines were followed in performing the detailed study that identified materials susceptible to aging, stressors, environmental factors, and failure modes for the RTS and ESFAS as generic instrumentation and control systems. Functional indicators of degradation are listed, testing requirements evaluated, and regulatory issues discussed.

ECG Feature Extraction Techniques - A Survey Approach  

E-Print Network [OSTI]

ECG Feature Extraction plays a significant role in diagnosing most of the cardiac diseases. One cardiac cycle in an ECG signal consists of the P-QRS-T waves. This feature extraction scheme determines the amplitudes and intervals in the ECG signal for subsequent analysis. The amplitudes and intervals value of P-QRS-T segment determines the functioning of heart of every human. Recently, numerous research and techniques have been developed for analyzing the ECG signal. The proposed schemes were mostly based on Fuzzy Logic Methods, Artificial Neural Networks (ANN), Genetic Algorithm (GA), Support Vector Machines (SVM), and other Signal Analysis techniques. All these techniques and algorithms have their advantages and limitations. This proposed paper discusses various techniques and transformations proposed earlier in literature for extracting feature from an ECG signal. In addition this paper also provides a comparative study of various methods proposed by researchers in extracting the feature from ECG signal.

AGING SYSTEM DESIGN DEVELOPMENT STRATEGY  

SciTech Connect (OSTI)

This plan provides an overview, work to date, and the path forward for the design development strategy of the Aging cask for aging commercial spent nuclear fuel (CSNF) at the Yucca Mountain Project (YMP) repository site. Waste for subsurface emplacement at the repository includes US Department of Energy (DOE) high-level radioactive waste (HLW), DOE SNF, commercial fuel in dual-purpose canisters (DPCs), uncanistered bare fuel, naval fuel, and other waste types. Table 1-1 lists the types of radioactive materials that may be aged at YMP, and those materials that will not be placed in an aging cask or module. This plan presents the strategy for design development of the Aging system. The Aging system will not handle naval fuel, DOE HLW, MCOs, or DOE SNF since those materials will be delivered to the repository in a state and sequence that allows them to be placed into waste packages for emplacement. Some CSNF from nuclear reactors, especially CSNF that is thermally too hot for emplacement underground, will need to be aged at the repository.

The annual report of the Center for Volcanic and Tectonic Studies (CVTS) contains a series of papers, maps, and reprints that review the progress made by the CVTS between October 1, 1991 and December 31, 1992. During this period CVTS staff focused on several topics that had direct relevance to volcanic hazards related to the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. These topics included: (1) The role of the mantle during regional extension. (2) The structural controls and emplacement mechanisms of Pliocene/Quaternary basaltic centers and dikes. (3) The detailed geochemistry of individual volcanic centers in Crater Flat, Nevada. (4) Estimating the probability of disruption of the proposed repository by volcanic eruption (this topic is being studied by Dr. C-H. Ho at UNLV).

Topology-based Feature Definition and Analysis  

SciTech Connect (OSTI)

Defining high-level features, detecting them, tracking them and deriving quantities based on them is an integral aspect of modern data analysis and visualization. In combustion simulations, for example, burning regions, which are characterized by high fuel-consumption, are a possible feature of interest. Detecting these regions makes it possible to derive statistics about their size and track them over time. However, features of interest in scientific simulations are extremely varied, making it challenging to develop cross-domain feature definitions. Topology-based techniques offer an extremely flexible means for general feature definitions and have proven useful in a variety of scientific domains. This paper will provide a brief introduction into topological structures like the contour tree and Morse-Smale complex and show how to apply them to define features in different science domains such as combustion. The overall goal is to provide an overview of these powerful techniques and start a discussion how these techniques can aid in the analysis of astrophysical simulations.

Naturally occurring heavy radioactive elements in the geothermal microcosm of the Los Azufres (Mexico) volcanic complex  

Science Journals Connector (OSTI)

Abstract The Los Azufres geothermal complex of central Mexico is characterized by fumaroles and boiling hot-springs. The fumaroles form habitats for extremophilic mosses and ferns. Physico-chemical measurements of two relatively pristine fumarolic microcosms point to their resemblance with the paleo-environment of earth during the Ordovician and Devonian periods. These geothermal habitats were analysed for the distribution of elemental mass fractions in the rhizospheric soil (RS), the native volcanic substrate (VS) and the sediments (S), using the new high-sensitivity technique of polarized x-ray energy dispersive fluorescence spectrometry (PEDXRF) as well as instrumental neutron activation analysis (INAA) for selected elements. This work presents the results for the naturally occurring heavy radioactive elements (NOHRE) Bi, Th and U but principally the latter two. For the RS, the density was found to be the least and the total organic matter content the most. Bi was found to be negligibly present in all substrate types. The average Th and U mass fractions in the RS were higher than in the VS and about equal to their average mass fractions in the S. The VS mass fraction of Th was higher, and of U lower, than the mass fractions in the earth's crust. In fact for the fumaroles of one site, the average RS mass fractions of these elements were higher than the averaged values for S (without considering the statistical dispersion). The immobilization of the NOHRE in the RS is brought about by the bio-geochemical processes specific to these extremophiles. Its effectiveness is such that despite the small masses of these plants, it compares with, or may sometimes exceed, the immobilization of the NOHRE in the S by the abiotic and aggressive chemical action of the hot-springs. These results indicate that the fumarolic plants are able to transform the volcanic substrate to soil and to affect the NOHRE mass fractions even though these elements are not plant nutrients. Mirrored back to the paleo times when such plant types were ubiquitous, it would mean that the first plants contributed significantly to pedogenesis and the biogeochemical recycling of even the heaviest and radioactive elements. Such plants may potentially be useful for the phytostabilisation of soil moderately contaminated by the NOHRE. Furthermore where applicable, geochronology may require taking into account the influence of the early plants on the NOHRE distributions.

Ebola outbreak in Conakry, Guinea: Epidemiological, clinical, and outcome features  

Science Journals Connector (OSTI)

AbstractObjectives The authors studied the epidemiological, clinical, and outcome features of the Ebola virus disease in patients hospitalized at the Ebola treatment center (ETC) in Conakry to identify clinical factors associated with death. Materials and methods A prospective study was conducted from March 25 to August 20, 2014. The diagnosis of Ebola virus infection was made on real-time PCR. Results Ninety patients, with a positive test result, were hospitalized. Their mean age was 34.12 ± 14.29 years and 63% were male patients. Most worked in the informal sector (38%) and in the medical and paramedical staff (physicians 12%, nurses 6%, and laboratory technicians 1%). Most patients lived in the Conakry suburbs (74%) and in Boffa (11%). The main clinical signs were physical asthenia (80%) and fever (72%). Hemorrhagic signs were observed in 26% of patients. The comparison of clinical manifestations showed that hiccups (P = 0.04), respiratory distress (P = 0.04), and hemorrhagic symptoms (P = 0.01) were more frequent among patients who died. Malaria (72%) and diabetes (2%) were the most frequent co-morbidities. The crude case fatality rate was 44% [95% confidence interval (33–54%)]. The average hospital stay was 7.96 ± 5.81 days. Conclusion The first Ebola outbreak in Conakry was characterized by the young age of patients, discrete hemorrhagic signs related to lethality. Its control relies on a strict use of preventive measures.

Late Jurassic extension in the Bisbee basin: Marine and volcanic strata of the Chiricahua Mountains, Arizona  

SciTech Connect (OSTI)

Upper Jurassic strata in the northeastern Chiricahua Mountains provide unambiguous stratigraphic and geographic links between the Chihuahua trough of north-central Mexico and the Bisbee basin of southeastern Arizona. Approximately 1,800 m of limestone, shale, and mafic volcanic rocks overlie the Glance Conglomerate and underlie fluvial redbeds of the Lower Cretaceous Morita Formation. Basal strata are alluvial-fan and sabkha deposits. A thick (150 m), ammonite-bearing black shale interval above the sabkha deposits indicates an abrupt increase of water depths; deepening was accompanied initially by emplacement of subaerial basalt flows and subsequently by deposition of basaltic tuff and pillow lava. Ammonites are present both below and above the tuff and indicate its exclusively subaqueous origin. Arkosic deltaic deposits above the tuff were derived from Precambrian rocks of the footwall block to the northeast. At least 200 m of mafic subaerial flows, previously regarded as mid-Tertiary, overlie the deltaic deposits. The existence of a depleted mantle source beneath the Bisbee basin at 150 Ma suggests a unique tectonic setting that combined backarc and Gulf of Mexico extension.

Analysis of fractures in volcanic cores from Pahute Mesa, Nevada Test Site  

SciTech Connect (OSTI)

The Nevada Test Site (NTS), located in Nye County, southern Nevada, was the location of 828 announced underground nuclear tests, conducted between 1951 and 1992. Approximately one-third of these tests were detonated near or below the water table. An unavoidable consequence of these testing activities was introducing radionuclides into the subsurface environment, impacting groundwater. Groundwater flows beneath the NTS almost exclusively through interconnected natural fractures in carbonate and volcanic rocks. Information about these fractures is necessary to determine hydrologic parameters for future Corrective Action Unit (CAU)-specific flow and transport models which will be used to support risk assessment calculations for the U.S. Department of Energy, Nevada Operations Office (DOE/NV) Underground Test Area (UGTA) remedial investigation. Fracture data are critical in reducing the uncertainty of the predictive capabilities of CAU-specific models because of their usefulness in generating hydraulic conductivity values and dispersion characteristics used in transport modeling. Specifically, fracture aperture and density (spacing) are needed to calculate the permeability anisotropy of the formations. Fracture mineralogy information is used qualitatively to evaluate diffusion and radionuclide retardation potential in transport modeling. All these data can best be collected through examination of core samples.

Predicting and validating the tracking of a Volcanic Ash Cloud during the 2006 Eruption of Mt. Augustine Volcano  

SciTech Connect (OSTI)

On 11 January 2006, Mount Augustine volcano in southern Alaska began erupting after 20-year repose. The Anchorage Forecast Office of the National Weather Service (NWS) issued an advisory on 28 January for Kodiak City. On 31 January, Alaska Airlines cancelled all flights to and from Anchorage after multiple advisories from the NWS for Anchorage and the surrounding region. The Alaska Volcano Observatory (AVO) had reported the onset of the continuous eruption. AVO monitors the approximately 100 active volcanoes in the Northern Pacific. Ash clouds from these volcanoes can cause serious damage to an aircraft and pose a serious threat to the local communities, and to transcontinental air traffic throughout the Arctic and sub-Arctic region. Within AVO, a dispersion model has been developed to track the dispersion of volcanic ash clouds. The model, Puff, was used operational by AVO during the Augustine eruptive period. Here, we examine the dispersion of a volcanic ash cloud from Mount Augustine across Alaska from 29 January through the 2 February 2006. We present the synoptic meteorology, the Puff predictions, and measurements from aerosol samplers, laser radar (or lidar) systems, and satellites. UAF aerosol samplers revealed the presence of volcanic aerosols at the surface at sites where Puff predicted the ash clouds movement. Remote sensing satellite data showed the development of the ash cloud in close proximity to the volcano and a sulfur-dioxide cloud further from the volcano consistent with the Puff predictions. Lidars showed the presence of volcanic aerosol with consistent characteristics aloft over Alaska and were capable of detecting the aerosol, even in the presence of scattered clouds and where the cloud is too thin/disperse to be detected by remote sensing satellite data. The lidar measurements revealed the different trajectories of ash consistent with the Puff predictions. Dispersion models provide a forecast of volcanic ash cloud movement that might be undetectable by any other means but are still a significant hazard. Validation is the key to assessing the accuracy of any future predictions. The study highlights the use of multiple and complementary observations used in detecting the trajectory ash cloud, both at the surface and aloft within the atmosphere.

Investigation of the thermal regime and geologic history of the Cascade volcanic arc: First phase of a program for scientific drilling in the Cascade Range  

SciTech Connect (OSTI)

A phased, multihole drilling program with associated science is proposed as a means of furthering our understanding of the thermal regime and geologic history of the Cascade Range of Washington, Oregon, and northern California. The information obtained from drilling and ancillary geological and geophysical investigations will contribute to our knowledge in the following general areas: (1) the magnitude of the regional background heat flow of parts of the Quaternary volcanic belt dominated by the most abundant volcanic rock types, basalt and basaltic andesite; (2) the nature of the heat source responsible for the regional heat-flow anomaly; (3) the characteristics of the regional hydrothermal and cold-water circulation; the rates of volcanism for comparison with models for the rate and direction of plate convergence of the Cascades; (5) the history of deformation and volcanism in the volcanic arc that can be related to subduction; (6) the present-day stress regime of the volcanic arc and the relation of these stresses to plate interactions and possible large earthquakes; and the current geometry of the subducted oceanic plate below the Cascade Range and the relationship of the plate to the distribution of heat flow, Quaternary volcanism, and Quaternary deformation. Phase I research will be directed toward a detailed investigation of the Santiam Pass segment. In concert with the Santiam Pass research, a detailed study of the nearby Breitenbush Hot Springs area is also recommended as a component of Phase I. The object of the Breitenbush research is to study one of the hottest known Cascade hydrothermal systems, which coincidentally also has a good geological and geophysical data base. A coordinated program of drilling, sampling, subsurface measurements, and surface surveys will be associated with the drilling of several holes.

Geology, geochemistry, and geochronology of volcanic rocks between Cuauhtemoc and La Junta, central Chihuahua, Mexico  

SciTech Connect (OSTI)

The 1200 km/sup 2/ area of this study straddles the boundary between the Sierra Madre Occidental and Basin and Range physiographic provinces and contains three north-northwest trending, block-faulted mountain ranges. The stratigraphy includes a 200 m thick sequence of ash-flow tuffs with subordinate mafic flows that either overlie or are interlayered with the ash-flow tuffs. This sequence overlies an approximately equal thickness of rhyolitic to dacitic flows and tuffs. At the base of the section occurs a distinctly different and thinner (about 50 m thick) sequence of flows, tuffs, and volcaniclastic sediments that is more nearly intermediate in average composition. The volcanic rocks of this study are primarily mafic and felsic with a bimodal distribution of Rb, Sr, and SiO/sub 2/ concentrations and other chemical parameters. The two modes have similar and overlapping ranges of initial /sup 87/Sr//sup 86/Sr ratios. Trace-element and major-element data generally support magmatic fractional crystallization as an important mechanism within each mode. Chemical trends within mafic rocks can be generated by 20 to 40% fractional crystallization of plagioclase and clinopyroxene (70:30 mixture). However, the formation of rhyolite or dacite from mafic rock requires implausible amounts of fractional crystallization of any proposed phenocryst assemblage, and thus the felsic rocks do not appear to be related to the mafic rocks by this mechanism. Most rhyolites of this study can form from dacitic liquid by 10 to 40% fractional crystallization of plagioclase and alkali feldspar (60:40 mixture).

Available potential energy of an isolated feature  

SciTech Connect (OSTI)

The true available potential energy (APE) of an isolated feature (e.g. a warm-core ring) in a basin is the difference in the potential plus internal energy between the observed and reference state. The reference state is that in which the same fluid is redistributed adiabatically to a stably stratified state and the isopycnals are on constant geopotential surfaces. For an isolated feature in an infinitely wide basin, it would seem reasonable to assume that the far-field density structure is a good approximation of the reference state. This approximation to the reference state will be examined in this paper. Four different methods of calculating the available potential of an isolated feature are compared. These are (1) the gravitational available potential energy using the reference state (APE/sub G/), (2) the gravitational available potential energy using the far-field density structure as an approximation for the reference state, (3) the Boussinesq available potential energy using the reference state (APE/sub B/), and (4) the Boussinesq available potential energy using the far-field density structure instead of the reference state. The gravitational available potential energy using the the reference state (APE/sub G/) is the true available potential energy for an incompressible fluid.

Age constraints on crystal-tuff from the Espinhaço Supergroup — Insight into the Paleoproterozoic to Mesoproterozoic intracratonic basin cycles of the Congo–São Francisco Craton  

Science Journals Connector (OSTI)

Abstract The U–Pb data from the volcanic and detrital zircon grains of the Tombador Formation in Chapada Diamantina, Bahia, provide the depositional age of the top of this unit and define the main sedimentary sources of the Archean, Paleoproterozoic and Mesoproterozoic Eras. The lithofacies, petrographic and geochemical data from crystal-tuff samples indicated that a volcanic source was located to the east of the Chapada Diamantina region. The available zircon data defined three first-order intracratonic basinal cycles, including the Lower (Statherian), Middle (Calymmian) and Upper (Stenian–early Tonian) Espinhaço basins. These sequences are well exposed at the Espinhaço Supergroup type-section in the Chapada Diamantina region. The zircon Hf isotope data from the 1.4 Ga crystal-tuff in the Middle Espinhaço and the 1.2 Ga tuffaceous rock in the Upper Espinhaço suggested different sources, with model ages of 2.1 to 1.9 Ga and Congo–São Francisco paleoplate interior recorded the main global events related to the geodynamic processes after the Columbia supercontinent collage and the formation and fragmentation of the Rodinia supercontinent.

Redeeming features of in situ combustion  

SciTech Connect (OSTI)

In situ combustion remains the most tantalizing enhanced oil recovery method. It has been tested extensively - in over 150 field tests - in both heavy and light oil reservoirs. What we have learned from this experience is that in situ combustion works under most conditions, but the nature of the problems is such that it is seldom profitable. Also, looking at many previous in situ combustion tests, steam injection, and even waterflooding, would have been a better choice. Yet in situ combustion has unique features not found in any other EOR method. These must be weighed against its shortcomings to evaluate a potential application. This paper discusses the redeeming features of in situ combustion, in particular the reservoir conditions under which in situ combustion may be superior to other EOR methods are outlined. All variations of in situ combustion - forward, reverse, wet, dry - as well as combinations with other EOR methods are considered. The conclusions is that in situ combustion still has a place, and its future application would depend on research on certain crucial aspects of the process.

Evaluation of Features, Events, and Processes (FEP) for the Biosphere Model  

SciTech Connect (OSTI)

The purpose of this analysis report is to evaluate and document the inclusion or exclusion of biosphere features, events, and processes (FEPs) with respect to modeling used to support the total system performance assessment (TSPA) for the license application (LA). A screening decision, either ''Included'' or ''Excluded'', is given for each FEP along with the corresponding technical basis for the excluded FEPs and the descriptions of how the included FEPs were incorporated in the biosphere model. This information is required by the U.S. Nuclear Regulatory Commission (NRC) regulations at 10 CFR 63.114 (d, e, and f) [DIRS 156605]. The FEPs addressed in this report concern characteristics of the reference biosphere, the receptor, and the environmental transport and receptor exposure pathways for the groundwater and volcanic ash exposure scenarios considered in biosphere modeling. This revision provides the summary of the implementation of included FEPs in TSPA-LA, (i.e., how the FEP is included); for excluded FEPs, this analysis provides the technical basis for exclusion from TSPA-LA (i.e., why the FEP is excluded). This report is one of the 10 documents constituting the biosphere model documentation suite. A graphical representation of the documentation hierarchy for the biosphere model is presented in Figure 1-1. This figure shows the interrelationships among the products (i.e., analysis and model reports) developed for biosphere modeling. The ''Biosphere Model Report'' describes in detail the biosphere conceptual model and mathematical model. The input parameter reports shown to the right of the ''Biosphere Model Report'' contain detailed descriptions of the model input parameters and their development. Outputs from these six reports are used in the ''Nominal Performance Biosphere Dose Conversion Factor Analysis and Disruptive Event Biosphere Dose Conversion Factor Analysis'' to generate the biosphere dose conversion factors (BDCFs), which are input parameters for the TSPA-LA model. The ''Biosphere Dose Conversion Factor Importance and Sensitivity Analysis'' analyzes the output of these two BDCF reports.

Paleotopography of glacial-age ice sheets  

SciTech Connect (OSTI)

This is technical comment and response to the subject of paleotophography of glacial age ice sheets. The model presented by Peltier reconstructing the paleotopography of glacial age ice sheets has implications for atmospheric general circulation models of ice age climate. In addition, the model suggests that the glacial-age Antarctic Ice Sheet was significantly larger than today`s. The commentor, Edwards, suggests there is a discrepancy between data from Papua New Guinea and the model results.

Innovative safety features of the modular HTGR  

SciTech Connect (OSTI)

The Modular High Temperature Gas-Cooled Reactor (MHTGR) is an advanced reactor concept under development through a cooperative program involving the US Government, the nuclear industry, and the utilities. Near-term development is focused on electricity generation. The top-level safety requirement is that the plant's operation not disturb the normal day-to-day activities of the public. Quantitatively, this requires that the design meet the US Environmental Protection Agency's Protective Action Guides at the site boundary and hence preclude the need for sheltering or evacuation of the public. To meet these stringent safety requirements and at the same time provide a cost competitive design requires the innovative use of the basic high temperature gas-cooled reactor features of ceramic fuel, helium coolant, and a graphite moderator. The specific fuel composition and core size and configuration have been selected to the use the natural characteristics of these materials to develop significantly higher margins of safety. In this document the innovative safety features of the MHTGR are reviewed by examining the safety response to events challenging the functions relied on to retain radionuclides within the coated fuel particles. A broad range of challenges to core heat removal are examined, including a loss of helium pressure of a simultaneous loss of forced cooling of the core. The challenges to control of heat generation consider not only the failure to insert the reactivity control systems but also the withdrawal of control rods. Finally, challenges to control of chemical attack of the ceramic-coated fuel are considered, including catastrophic failure of the steam generator, which allows water ingress, or failure of the pressure vessels, which allows air ingress. The plant's response to these extreme challenges is not dependent on operator action, and the events considered encompass conceivable operator errors.

Solid Friction from stick-slip to pinning and aging  

E-Print Network [OSTI]

We review the present state of understanding of solid friction at low velocities and for systems with negligibly small wear effects. We first analyze in detail the behavior of friction at interfaces between wacroscopic hard rough solids, whose main dynamical features are well described by the Rice-Ruina rate and state dependent constitutive law. We show that it results from two combined effects : (i) the threshold rheology of nanometer-thick junctions jammed under confinement into a soft glassy structure (ii) geometric aging, i.e. slow growth of the real arrea of contact via asperity creep interrupted by sliding. Closer analysis leads to identifying a second aging-rejuvenation process, at work within the junctions themselves. We compare the effects of structural aging at such multicontact, very highly confined, interfaces with those met under different confinement levels, namely boundary lubricated contacts and extended adhesive interfaces involving soft materials (hydrogels, elastomers). This leads us to propose a classification of frictional junctions in terms of the relative importance of jamming and adsoprtion-induced metastability.

No Evidence for Significant Age Spreads in Young Massive LMC Clusters  

E-Print Network [OSTI]

Recent discoveries have put the picture of stellar clusters being simple stellar populations into question. In particular, the color-magnitude diagrams of intermediate age (1-2 Gyr) massive clusters in the Large Magellanic Cloud (LMC) show features that could be interpreted as age spreads of 100-500 Myr. If multiple generations of stars are present in these clusters then, as a consequence, young (test this hypothesis. We analyzed the color-magnitude diagrams of these clusters and fitted their star formation history to derive upper limits of potential age spreads. We find that none of the clusters analyzed in this work shows evidence for an extended star formation history that would be consistent with the age spreads proposed for intermediat...

Features, Events, and Processes: system Level  

SciTech Connect (OSTI)

The purpose of this analysis report is to evaluate and document the inclusion or exclusion of the system-level features, events, and processes (FEPs) with respect to modeling used to support the total system performance assessment for the license application (TSPA-LA). A screening decision, either Included or Excluded, is given for each FEP along with the technical basis for screening decisions. This information is required by the U.S. Nuclear Regulatory Commission (NRC) at 10 CFR 63.113 (d, e, and f) (DIRS 156605). The system-level FEPs addressed in this report typically are overarching in nature, rather than being focused on a particular process or subsystem. As a result, they are best dealt with at the system level rather than addressed within supporting process-level or subsystem-level analyses and models reports. The system-level FEPs also tend to be directly addressed by regulations, guidance documents, or assumptions listed in the regulations; or are addressed in background information used in development of the regulations. For included FEPs, this analysis summarizes the implementation of the FEP in the TSPA-LA (i.e., how the FEP is included). For excluded FEPs, this analysis provides the technical basis for exclusion from the TSPA-LA (i.e., why the FEP is excluded). The initial version of this report (Revision 00) was developed to support the total system performance assessment for site recommendation (TSPA-SR). This revision addresses the license application (LA) FEP List (DIRS 170760).

Design Feature 7: Continuous Preclosure Ventilation  

SciTech Connect (OSTI)

This design feature (DF) is intended to evaluate the effects of continuous ventilation in the emplacement drifts during preclosure and how the effects, if any, compare to the Viability Assessment (VA) reference design for postclosure long term performance. This DF will be evaluated against a set of criteria provided by the License Application Design Selection (LADS) group. The VA reference design included a continuous ventilation airflow quantity of 0.1 m{sup 3}/s in the emplacement drifts in the design of the repository subsurface facilities. The effects of this continuous ventilation during the preclosure was considered to have a negligible effect on postclosure performance and therefore is not included during postclosure in the assessment of the long term performance. This DF discusses the effects of continuous ventilation on the emplacement drift environment and surrounding rock conditions during preclosure for three increased airflow quantities. The three cases of continuous ventilation systems are: System A, 1.0 m{sup 3}/s (Section 8), System B, 5.0 m{sup 3}/s (Section 9), and System C, 10.0 m{sup 3}/s (Section 10) in each emplacement drift split. An emplacement drift split is half total length of emplacement drift going from the east or west main to the exhaust main. The difference in each system is the quantity of airflow in the emplacement drifts.

The FEPs addressed in this report deal with both seismic and igneous disruptive events, such as fault displacements through the repository and an igneous intrusion into the repository. For included FEPs, this analysis summarizes the implementation of the FEP in TSPA-LA (i.e., how the FEP is included). For excluded FEPs, this analysis provides the technical basis for exclusion from TSPA-LA (i.e., why the FEP is excluded). Previous versions of this report were developed to support the total system performance assessments (TSPA) for various prior repository designs. This revision addresses the repository design for the license application (LA).

Possible Origin of Improved High Temperature Performance of Hydrothermally Aged Cu/Beta Zeolite Catalysts  

SciTech Connect (OSTI)

The hydrothermal stability of Cu/beta NH3 SCR catalysts are explored here. In particular, this paper focuses on the interesting ability of this catalyst to maintain and even enhance high-temperature performance for the "standard" SCR reaction after modest (900 °C, 2 hours) hydrothermal aging. Characterization of the fresh and aged catalysts was performed with an aim to identify possible catalytic phases responsible for the enhanced high temperature performance. XRD, TEM and 27Al NMR all showed that the hydrothermally aging conditions used here resulted in almost complete loss of the beta zeolite structure between 1 and 2 hours aging. While the 27Al NMR spectra of 2 and 10 hour hydrothermally-aged catalysts showed significant loss of a peak associated with tetrahedrally-coordinated Al species, no new spectral features were evident. Two model catalysts, suggested by these characterization data as possible mimics of the catalytic phase formed during hydrothermal aging of Cu/beta, were prepared and tested for their performance in the "standard" SCR and NH3 oxidation reactions. The similarity in their reactivity compared to the 2 hour hydrothermally-aged Cu/beta catalyst suggests possible routes for preparing multi-component catalysts that may have wider temperature windows for optimum performance than those provided by current Cu/zeolite catalysts.

Transition from alkaline to calc-alkaline volcanism during evolution of the Paleoproterozoic Francevillian basin of eastern Gabon (Western Central Africa)  

Science Journals Connector (OSTI)

Abstract We report new geochemical data for the volcanic and subvolcanic rocks associated with the evolution of the Francevillian basin of eastern Gabon during Paleoproterozoic times (c. 2.1–2 Ga). Filling of this basin has proceeded through four main sedimentary or volcano-sedimentary episodes, namely FA, FB, FC and FD. Volcanism started during the FB episode being present only in the northern part of the basin (Okondja sub-basin). This volcanism is ultramafic to trachytic in composition and displays a rather constant alkaline geochemical signature. This signature is typical of a within-plate environment, consistent with the rift-setting generally postulated for the Francevillian basin during the FB period. Following FB, the FC unit is 10–20 m-thick silicic horizon (jasper) attesting for a massive input of silica in the basin. Following FC, the FD unit is a c. 200–400 m-thick volcano-sedimentary sequence including felsic tuffs and epiclastic rocks. The geochemical signatures of these rocks are totally distinct from those of the FB alkaline lavas. High Th/Ta and La/Ta ratios attest for a calc-alkaline signature and slight fractionation between heavy rare-earth suggests melting at a rather low pressure. Such characteristics are comparable to those of felsic lavas associated with the Taupo zone of New Zealand, a modern ensialic back-arc basin. Following FD, the FE detrital unit is defined only in the Okondja region, probably associated with a late-stage collapse of the northern part of the basin. It is suggested that the alkaline to calc-alkaline volcanic transition reflects the evolution of the Francevillian basin from a diverging to a converging setting, in response to the onset of converging movements in the Eburnean Belt of Central Africa.

Re–Os depositional ages and seawater Os estimates for the Frasnian–Famennian boundary: Implications for weathering rates, land plant evolution, and extinction mechanisms  

Science Journals Connector (OSTI)

Four TOC-rich shale intervals spanning the Frasnian–Famennian (F–F) boundary were recovered in a drillcore (West Valley NX-1) from western New York (USA) and radiometrically dated using Re–Os. Two of the black shale intervals (WVC785 from ? 2.9 m below, and WVC754 from ? 6.4 m above the F–F boundary, respectively) yielded statistically overlapping ages with uncertainties of < 1.1%. An interpolated age and associated graphically determined uncertainty of 372.4 ± 3.8 Ma provides new absolute age constraints on the F–F boundary. This date is ? 4.1 Ma younger than the latest proposed F–F boundary age of 376.1 Ma obtained by interpolation of U–Pb dates from volcanic zircon [Kaufmann, B., 2006. Calibrating the Devonian Time Scale: A synthesis of U–Pb ID-TIMS ages and conodont stratigraphy. Earth-Science Reviews 76, 175–190], and within uncertainty of the International Commission on Stratigraphy accepted date of 374.5 ± 2.6 Ma. A third date (from sample WVC802, ? 8.2 m beneath the F–F boundary) yielded an imprecise age of 357 ± 23 Ma, owing in part to a limited Re/Os range. The initial 187Os/188Os (0.45 to 0.47), reflecting contemporaneous seawater Os values, are low but similar to the value of 0.42 reported for the Exshaw Fm (Canada) at the Devonian–Mississippian boundary (ca. 361 Ma) [Selby D., Creaser R.A., 2005. Direct radiometric dating of the Devonian–Mississippian time-scale boundary using the Re–Os black shale geochronometer. Geology 33, 545–548]. This may suggest fairly constant and low global continental weathering rates during the Late Devonian, although in view of the short residence time of Os in seawater (? 1–4 × 104 yr), further measurements are needed to assess potential short-term variation in seawater Os ratios. Owing to low Os and Re abundances at the F–F boundary, our data are inconsistent with long-term volcanism and bolide impact as potential Late Devonian mass extinction mechanisms. In addition, the Frasnian–Famennian ocean appears to have been depleted with respect to Re, possibly indicating an exhaustion of the Re seawater reservoir owing to high burial rates of redox-sensitive elements under dysoxic/anoxic conditions leading up to the F–F boundary.

THE EXTENSIVE AGE GRADIENT OF THE CARINA DWARF GALAXY  

SciTech Connect (OSTI)

The evolution of small systems such as dwarf spheroidal galaxies (dSphs) is likely to have been a balance between external environmental effects and internal processes within their own relatively shallow potential wells. Assessing how strong such environmental interactions may have been is therefore an important element in understanding the baryonic evolution of dSphs and their derived dark matter distribution. Here we present results from a wide-area CTIO/MOSAIC II photometric survey of the Carina dSph, reaching down to about two magnitudes below the oldest main-sequence turnoff (MSTO). This data set enables us to trace the structure of Carina in detail out to very large distances from its center, and as a function of stellar age. We observe the presence of an extended structure made up primarily of ancient MSTO stars, at distances between 25' and 60' from Carina's center, confirming results in the literature that Carina extends well beyond its nominal tidal radius. The large number statistics of our survey reveals features such as isophote twists and tails that were undetected in other previous, shallower surveys. This is the first time that such unambiguous signs of tidal disruption have been found in a Milky Way 'classical' dwarf other than Sagittarius. We also demonstrate the presence of a negative age gradient in Carina directly from its MSTOs, and trace it out to very large distances from the galaxy center. The signs of interaction with the Milky Way make it unclear whether the age gradient was already in place before Carina underwent tidal disruption.

A commodity approach to aging management review of supports for license renewal  

SciTech Connect (OSTI)

10CFR Part 54 requires that nuclear power plant licensees who seek renewal of their operating licenses for an additional 20 years of operation (i.e., for a total operating life of 60 years) perform an Integrated Plant Assessment (IPA) on all systems, structures and components (SSCs) within the scope of license renewal. Baltimore Gas and Electric (BGE) and MPR Associates, Inc., have recently completed an aging management review of component supports for Calvert Cliffs Nuclear Power Plant (CCNPP). A commodity approach was used on the basis that component supports perform essentially the same function regardless of the system with which they are associated. This approach, i.e., treating component supports as commodities as opposed to performing the aging management review for each individual component support, resulted in a cost-effective approach for this portion of the IPA. An important feature of the aging management review of component support at CCNPP is the evaluation of the adequacy of existing programs to manage component support aging. Two major programs were included in the evaluation: the ASME Section 11 In-Service Inspection (ISI) Program, and CCNPP`s Seismic Verification Project to resolve USI A-46. The key role that these programs play in the overall aging management strategy for component supports, as well as the evaluation of other on-going activities which complete the aging management approach for component supports, are discussed.

Combining power spectrum and bispectrum measurements to detect oscillatory features  

E-Print Network [OSTI]

The simplest inflationary models present us with few observable parameters to discriminate between them. A detection of features in the spectra of primordial density perturbations could provide valuable insights and lead to stringent tests of models of the early universe. So far, searches for oscillatory features have not produced statistically significant results. In this work we consider a combined search for features in the power spectrum and bispectrum. We show that possible dependencies between the estimates of feature model amplitudes based on the two and three-point correlators are largely statistically independent under the assumption of the null hypothesis of a nearly Gaussian featureless CMB. Building on this conclusion we propose an optimal amplitude estimator for a combined search and study the look-elsewhere effect in feature model surveys. In particular we construct analytic models for the distribution of amplitude estimates that allow for a reliable assessment of the significance of potential f...

Unsupervised Feature Learning for High-Resolution Satellite Image Classification  

SciTech Connect (OSTI)

The rich data provided by high-resolution satellite imagery allow us to directly model geospatial neighborhoods by understanding their spatial and structural patterns. In this paper we explore an unsupervised feature learning approach to model geospatial neighborhoods for classification purposes. While pixel and object based classification approaches are widely used for satellite image analysis, often these approaches exploit the high-fidelity image data in a limited way. In this paper we extract low-level features to characterize the local neighborhood patterns. We exploit the unlabeled feature measurements in a novel way to learn a set of basis functions to derive new features. The derived sparse feature representation obtained by encoding the measured features in terms of the learned basis function set yields superior classification performance. We applied our technique on two challenging image datasets: ORNL dataset representing one-meter spatial resolution satellite imagery representing five land-use categories and, UCMERCED dataset consisting of 21 different categories representing sub-meter resolution overhead imagery. Our results are highly promising and, in the case of UCMERCED dataset we outperform the best results obtained for this dataset. We show that our feature extraction and learning methods are highly effective in developing a detection system that can be used to automatically scan large-scale high-resolution satellite imagery for detecting large-facility.

Couplers that link together two or more numerical simulations are well-known abstractions in the Earth System Modeling (ESM) community. In the past decade, reusable software assets have emerged to facilitate scientists in implementing couplers. While there is a large amount of overlap in the features supported by software coupling technologies, their implementations differ significantly in terms of both functional and non-functional properties. Using a domain analysis method called feature analysis, we explore the spectrum of features supported by coupling technologies used to build today's production ESMs.

Feature-Based Statistical Analysis of Combustion Simulation Data  

SciTech Connect (OSTI)

We present a new framework for feature-based statistical analysis of large-scale scientific data and demonstrate its effectiveness by analyzing features from Direct Numerical Simulations (DNS) of turbulent combustion. Turbulent flows are ubiquitous and account for transport and mixing processes in combustion, astrophysics, fusion, and climate modeling among other disciplines. They are also characterized by coherent structure or organized motion, i.e. nonlocal entities whose geometrical features can directly impact molecular mixing and reactive processes. While traditional multi-point statistics provide correlative information, they lack nonlocal structural information, and hence, fail to provide mechanistic causality information between organized fluid motion and mixing and reactive processes. Hence, it is of great interest to capture and track flow features and their statistics together with their correlation with relevant scalar quantities, e.g. temperature or species concentrations. In our approach we encode the set of all possible flow features by pre-computing merge trees augmented with attributes, such as statistical moments of various scalar fields, e.g. temperature, as well as length-scales computed via spectral analysis. The computation is performed in an efficient streaming manner in a pre-processing step and results in a collection of meta-data that is orders of magnitude smaller than the original simulation data. This meta-data is sufficient to support a fully flexible and interactive analysis of the features, allowing for arbitrary thresholds, providing per-feature statistics, and creating various global diagnostics such as Cumulative Density Functions (CDFs), histograms, or time-series. We combine the analysis with a rendering of the features in a linked-view browser that enables scientists to interactively explore, visualize, and analyze the equivalent of one terabyte of simulation data. We highlight the utility of this new framework for combustion science; however, it is applicable to many other science domains.

Interaction between mantle-derived and crustal calc-alkaline magmas in the petrogenesis of the Paleocene Sifton Range volcanic complex, Yukon, Canada  

Science Journals Connector (OSTI)

The uplifted plutons of the eastern Coast Plutonic Complex (CPC) of the northern Canadian Cordillera are in contact with coeval volcanic suites of the early Tertiary Sloko-Skukum Group, offering a unique opportunity to address the relationship between subduction-related, continental calc-alkaline volcanic sequences and their coeval granitoid suites. The Sifton Range volcanic complex (SRVC) of southwestern Yukon is intruded by CPC granites and displays a subduction-related geochemical signature with depletions in HFSE relative to LILE. The volcanic rocks range between medium- and high-K orogenic suites, and define a calc-alkaline fractionation trend. The epizonal potassium–feldspar granites are chemically similar to the SRVC rhyolites, and are characterized by highly fractionated LREE (LaN / SmN = 5–11), enrichments in LILE and Th (12–18 ppm). The SRVC exhibits a striking relationship between rock composition and style of eruption, with a reduction in abundance of lavas with increasing SiO2 being correlated with the appearance of felsic pyroclastic rocks and granitic plutonism. Thermodynamic crystal fractionation models of the compositional interval between basaltic and dacitic andesite (52–61 wt.% SiO2) are consistent with evolution at moderately hydrous (1.5 wt.% H2O), upper crustal (1.5 kbar) conditions, and fO2 close to the QFM buffer. Neither assimilation-fractional crystallization (AFC), nor binary magma mixing models are capable of explaining the anomalously elevated Th contents in the SRVC felsic lavas and granites. Furthermore, unrealistically high contamination factors (r > 2.5) are required in AFC models to attain the incompatible-element concentrations of the SRVC granite and rhyolites, suggesting they represent distinct melts derived by anatexis of enriched upper crust, rather than the evolved products of the mafic SRVC magma. Changes in crystallinity during evolution of the SRVC magmas imply an abrupt rise in effective viscosity (from 106 to 1010 Pa s) near the andesite–dacite transition as a result of the flocculation of plagioclase phenocrysts. The resultant increase in shear strength impeded crystal fractionation and eruption of lavas, and may account for the decrease in the abundance of flows with more than 62 wt.% SiO2. The onset of explosive volcanism at c.a. 68 wt.% SiO2 approximately coincides with the calculated saturation point of H2O at 1.5 kbar in the hybridized dacite magmas. Alternating mafic and felsic volcanic stratigraphy along with the presence of compositionally bimodal pyroclastics and mixed phenocrysts in the SRVC dacites suggest that mantle-derived magmas and crustal melts coexisted in a zoned magmatic column undergoing episodic injection of juvenile melts. Sudden release of volatiles from the hybrid dacitic magmas along the interface with the overlying anatectic crystal mush may have triggered the cycle of explosive eruptions of dominantly rhyolitic ejecta. The consequent loss of volatiles further promoted feldspar crystallization eventually favouring magma stagnation and plutonism.

Restructuring and aging in a capillary suspension  

E-Print Network [OSTI]

The rheological properties of capillary suspensions, suspensions with small amounts of an added immiscible fluid, are dramatically altered with the addition of the secondary fluid. We investigate a capillary suspension to determine how the network ages and restructures at rest and under applied external shear deformation. The present work uses calcium carbonate suspended in silicone oil (11 % solids) with added water as a model system. Aging of capillary suspensions and their response to applied oscillatory shear is distinctly different from particulate gels dominated by the van der Waals forces. The suspensions dominated by the capillary force are very sensitive to oscillatory flow, with the linear viscoelastic regime ending at a deformation of only 0.1 % and demonstrating power-law aging behavior. This aging persists for long times at low deformations or for shorter times with a sudden decrease in the strength at higher deformations. This aging behavior suggests that the network is able to rearrange and even rupture. This same sensitivity is not demonstrated in shear flow where very high shear rates are required to rupture the agglomerates returning the apparent viscosity of capillary suspensions to the same viscosity as for the pure vdW suspension. A transitional region is also present at intermediate water contents wherein the material response depends very strongly on the type, strength, and duration of the external forcing.

Personalized Translation Listening System for Age Groups  

Science Journals Connector (OSTI)

Present translation systems play back their results with specific speed and volume regardless of the type of user. In this paper, we describe a personalized translation listening system by identifying user information. User groups are classified by age group after inputting speech. This suggested translation system gives the translated result back to the user, speaking at an emphasized speech based on the user's age. The personalized translation listening system performs age recognition, speech recognition, language recognition, Google machine translation, and TTS web services. We showed the comparison of normal speech and emphasized speech by realizing a user-oriented translation system in a mobile device. A Mean Opinion Score was used for the experiment. Average score of the Mean Opinion Score experiment was 3.21.

Effective temperature of an aging powder  

Science Journals Connector (OSTI)

The aging dynamics and the fluctuation-dissipation relation between the spontaneous diffusion induced by a random noise and the drift motion induced by a small stirring force are numerically investigated in a 3D schematic model of compacting powder: a gravity-driven lattice-gas with purely kinetic constraints. The compaction dynamics is characterized by a super-aging behavior and, in analogy with glasses, exhibits a purely dynamical time-scale-dependent effective temperature. A simple experiment to measure this quantity is suggested.

Aging assessment for active fire protection systems  

SciTech Connect (OSTI)

This study assessed the impact of aging on the performance and reliability of active fire protection systems including both fixed fire suppression and fixed fire detection systems. The experience base shows that most nuclear power plants have an aggressive maintenance and testing program and are finding degraded fire protection system components before a failure occurs. Also, from the data reviewed it is clear that the risk impact of fire protection system aging is low. However, it is assumed that a more aggressive maintenance and testing program involving preventive diagnostics may reduce the risk impact even further.

Thermal aging of nitroplasticized Estane 5703  

SciTech Connect (OSTI)

In support of the Lifetime Prediction modeling effort, we have been investigating the aging processes that could impact the lifetime of PBX 9501. PBX 9501 is composed of 95% HMX and 5% polymeric binder. The polymeric binder is composed of 50% nitroplasticizer (NP) and 50% Estane{reg_sign} 5703 with a small quantity of stabilizer. Estane{reg_sign} 5703 is a segmented poly(ester urethane) with mechanical properties derived from phase separation of hard and soft segments along the polymer backbone. Since the binder has a significant effect on the composite mechanical properties, it is essential to know how the binder changes with time. Typically, polymer lifetime predictions are determined from extrapolation of properties after the material has been exposed to elevated temperatures and/or reactive environments for varying periods of time. For multiphase polymers, this accelerated aging methodology is very difficult to interpret since elevated temperatures alter the physical structure of the polymer, as well as, accelerate the chemical degradation reactions. Accelerated aging studies of nitroplasticized Estane have shown an increase in the molecular weight. The increase in molecular weight is most likely due to polymer chain branching reactions that eventually leads to formation an insoluble cross-linked gel. The decreased chain mobility caused by branching may also affect phase separation, which in turn, may change the mechanical properties. In this paper we report results of thermal aging studies on the properties, morphology and chemistry of nitroplasticized Estane.

Characterizing mechanical effects of aging damage  

SciTech Connect (OSTI)

This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The goal was to develop and apply several different experimental and theoretical/computational tools to better understand physical and chemical aging phenomena in plastic-bonded high explosives, and to develop a methodology for predicting the likely effects of aging on the mechanical properties of the composite based on input from these fundamental studies. Initial comparisons were done for spectra of fresh and aged Esane, as well as PBX-9501, and the authors found differences in the carbonyl region of the spectrum, which possibly reflect differences in hydrogen bonding due to aging phenomena. The micromechanical model of composites was extended to study various volume fractions of HMX with binders. The results showed that, as the binder fraction increases, there is a decrease in the maximum stress that can be supported but an increase in the percent strain at final fracture. A more realistic microstructural model was obtained through the use of a phase field model. Using this model, the authors have studied the microstructural evolution as a function of the grain boundary energy vs. misorientation relationship. The initial results indicate that there are some changes in the grain growth rate when the grain-boundary energy dependence on the angle is not constant. They also find that solute tends to segregate at the grain boundary and slows the grain growth kinetics.

Genetic programming approach to extracting features from remotely sensed imagery  

SciTech Connect (OSTI)

Multi-instrument data sets present an interesting challenge to feature extraction algorithm developers. Beyond the immediate problems of spatial co-registration, the remote sensing scientist must explore a complex algorithm space in which both spatial and spectral signatures may be required to identify a feature of interest. We describe a genetic programming/supervised classifier software system, called Genie, which evolves and combines spatio-spectral image processing tools for remotely sensed imagery. We describe our representation of candidate image processing pipelines, and discuss our set of primitive image operators. Our primary application has been in the field of geospatial feature extraction, including wildfire scars and general land-cover classes, using publicly available multi-spectral imagery (MSI) and hyper-spectral imagery (HSI). Here, we demonstrate our system on Landsat 7 Enhanced Thematic Mapper (ETM+) MSI. We exhibit an evolved pipeline, and discuss its operation and performance.

SOLAR MAGNETIC TRACKING. IV. THE DEATH OF MAGNETIC FEATURES  

SciTech Connect (OSTI)

The removal of magnetic flux from the quiet-Sun photosphere is important for maintaining the statistical steady state of the magnetic field there, for determining the magnetic flux budget of the Sun, and for estimating the rate of energy injected into the upper solar atmosphere. Magnetic feature death is a measurable proxy for the removal of detectable flux, either by cancellation (submerging or rising loops, or reconnection in the photosphere) or by dispersal of flux. We used the SWAMIS feature tracking code to understand how nearly 2 Multiplication-Sign 10{sup 4} magnetic features die in an hour-long sequence of Hinode/SOT/NFI magnetograms of a region of the quiet Sun. Of the feature deaths that remove visible magnetic flux from the photosphere, the vast majority do so by a process that merely disperses the previously detected flux so that it is too small and too weak to be detected, rather than completely eliminating it. The behavior of the ensemble average of these dispersals is not consistent with a model of simple planar diffusion, suggesting that the dispersal is constrained by the evolving photospheric velocity field. We introduce the concept of the partial lifetime of magnetic features, and show that the partial lifetime due to Cancellation of magnetic flux, 22 hr, is three times slower than previous measurements of the flux turnover time. This indicates that prior feature-based estimates of the flux replacement time may be too short, in contrast with the tendency for this quantity to decrease as resolution and instrumentation have improved. This suggests that dispersal of flux to smaller scales is more important for the replacement of magnetic fields in the quiet Sun than observed bipolar cancellation. We conclude that processes on spatial scales smaller than those visible to Hinode dominate the processes of flux emergence and cancellation, and therefore also the quantity of magnetic flux that threads the photosphere.

A distinctive feature of the surface structure of quasicrystals  

SciTech Connect (OSTI)

This paper reviews a feature of atomically-clean quasicrystal surfaces that distinguishes them from surfaces of crystalline materials. That feature is a high degree of heterogeneity among different terraces, and among structurally-identical adsorption sites. The heterogeneity can be both structural and chemical in origin. A large variability is expected even for a surface which is perfectly bulk-terminated, and we call this intrinsic heterogeneity. Additional variability can derive from the surface preparation process, which can yield metastable structures. We call this extrinsic heterogeneity. Experimental evidence is given for both cases. This heterogeneity can be an important factor in understanding and predicting surface phenomena such as chemisorption.

Is the silicate emission feature only influenced by grain size?  

E-Print Network [OSTI]

The flattening of the 10mu silicate emission feature observed in the spectra of T Tauri and Herbig Ae/Be stars is usually interpreted as an indicator of grain growth. We show in this paper that a similar behaviour of the feature shape occurs when the porosity of composite grains varies. The fluffy aggregates, having inclusions of different sizes, were modeled by multi-layered spheres consisting of amorphous carbon, amorphous silicate and vacuum. It is also found that the inclusion of crystalline silicates in composite porous particles can lead to a shift of the known resonances and production of new ones.

Aging influence on exergy destruction in an operating 320MW steam power plant  

Science Journals Connector (OSTI)

Exergy analysis in power plants is a strong tool to evaluate cycle performance qualitatively. Most of previous studies applied second law approach to find optimum values for main cycle parameters. Although these researches are useful to improve the design features of future power plants they do not imply any recommendation to improve an aged unit. In This study an exergy analysis of an operating unit was performed to clear main sources of exergy destruction. Second law efficiency and exergy losses of all main components in the steam power plant which is located in the south of Iran were calculated based on present data. To find out aging influence on the plant performance outcomes were compared with design results. This comparison cleared components which affected by aging and the amount of miss performance were specified too. Boiler and high pressure turbine (HP) were the most influenced components due to aging effects. Besides the calculations were done at three loads in order to evaluate performance of components in off design conditions.

Comparison of organic-rich shales of Pennsylvanian age in Indiana with New Albany Shale  

SciTech Connect (OSTI)

Abundant black organic-rich shales occur in rocks of Pennsylvanian age in southwestern Indiana. They have not been well characterized except for a few thin intervals in small areas, the best example being at the abandoned Mecca Quarry in west-central Indiana. Although these shales are thinner and less widespread than the organic-rich shales of the New Albany Shale (Devonian and Mississippian age) they warrant characterization because of their accessibility during strip mining of underlying coals. Organic-rich shales of Pennsylvanian age contain up to 44% organic carbon and might be considered potential oil shales. Carbon to hydrogen ratios in these shales are similar to those in the New Albany. Relatively high concentrations of certain metals occur in shales of both ages, especially where phosphate is abundant, and sulfur values for both shales range from < 1 to 6%. Sulfur values are much higher for thin pyrite-rich units. Siderite nodules are common in Pennsylvania shales, but little siderite if found in the New Albany. Dolomite, commonly ferroan, and calcite in a variety of forms are the dominant carbonates in the New Albany. Some Pennsylvanian shales may contain large fossils or mica flakes, but such coarse-grained features are uncommon in the New Albany Shale.

Accelerated aging of EPDM and butyl elastomers  

SciTech Connect (OSTI)

This study was composed of three parts: a post cure study to optimize final properties of an ethylene-propylene-diene (EPDM) formulation, an accelerated aging study to compare the stress relaxation behavior of a butyl and an EPDM elastomer under compression, and a cursory evaluation of a new 70 Shore A EPDM. The optimum postcure for the EPDM was found to be 2 to 4 hours at 182{degrees}C in a vacuum. The EPDM was also shown to have superior aging characteristics compared to the butyl and is recommended for use instead of the butyl material. The physical properties for new 70 Shore A EPDM are satisfactory, and the stress relaxation behavior was only slightly inferior to the other EPDM.
