  • The 1,400 km long Beringian margin is characterized by several very large submarine canyons and by a large oceanic plateau at the southern end. GLORIA sidescan-sonar imagery provides a perspective of this margin that is unattainable with conventional acoustic profiles. The broad coverage of GLORIA images emphasizes that, of all the sedimentary processes affecting this vast margin, mass movement is clearly the dominant shaping process. Styles of failure include mud and debris flows, slumps, and massive block slides, some covering areas greater than 1,500 km{sup 2}. GLORIA imagery and seismic-reflection profiles show evidence for a wide variety of slides andmore » slumps in the canyons of the northern margin, Navarin and Pervenets. The 100 km long shelf edge between these two canyons is characterized by a series of scalloped slide scars and incipient scars associated with blocks of sedimentary material, 1 to 2 km across. One of the largest single slide masses is a huge block tens of kilometers wide that occurs on the rise in the central part of the margin beyond the mouth of Zhemchug Canyon. Sliding of this block may have initiated the incision of the world's largest submarine canyon. The removal of this block accelerated headward erosion by retrograde failure until Zhemchug Canyon was cut back to a fault parallel to the shelf edge. Mass movement along the southern margin is widespread at the edges of Umnak Plateau. One mass failure, well-defined by GLORIA, is about 30 km wide and 55 km long. This and other slides along the plateau are associated with diapiric-like structures, suggesting relatively recent tectonism.« less
  • Numerous rock slope failures have occurred in major road cuts in Southwestern Pennsylvania over the past several years. Most of these cuts have existed for 25 to 30 years. The obvious hazard to motorists, pedestrians, and the roadway itself has prompted the Pennsylvania Department of Transportation to undertake a comprehensive study of several major cut slopes to determine their stability, both present and long term, and to formulate plans for remedial work where it is considered necessary. A detailed study was completed recently of five large cuts along a two mile stretch of US Route 51 next to the Ohiomore » River in Beaver County, Pennsylvania. The study combined structural geology data and computer models of existing and proposed cut slope configurations. Results of the investigation indicate that the slope will not undergo major failures involving large quantities of rock. Rather, failures will be localized and will involve several cubic yards to several hundred cubic yards of rock. Types of rock failures that occur on this series of road cuts are dominantly plane failures along joint surfaces, with rock falls and joint controlled wedge failures being minor in abundance. Plane failures occur in sandy shale and sandstone beds on joints that are parallel to the Ohio River. The road cuts were made along these joints rather than by well planned rock slope engineering methods. The strike of the joints is parallel to the strike of local fold axes suggesting structural control of the formation of joints. Measures recommended to reduce the potential of rock slides include flattering the slopes, rock bolts, anchored wire mesh, shotcrete, buttresses, and drainage systems.« less
  • Syndepositional slumps and slide are commonly used as proxy indicators of paleoslope direction in the absence of direct evidence for the direction of the depositional slope. The direct measurement of depositional slope compared with the orientations of slump fold axes allows calibration of this method of paleoslope determination. The Pliocene Mao Fm. is a 400-600 meter thick limestone and siliciclastic unit located in the Cibao Valley, Dominican Republic. The sandstone and conglomeratic basal portion of the formation contains 30 cm to 3 m high, synsedimentary, generative, recumbant folds formed during submarine slumping and sliding. The orientations of 17 fold axesmore » in 12 different folds show a bimodal distribution with distinct modes for folds with upslope and downslope closure. The range of axes for folds with upslope closure (40/sup 0/) is smaller than that for folds with downslope closure (135/sup 0/). The mean axis orientation for all folds is N6/sup 0/W with individual means for folds with upslope and downslope closure being N41/sup 0/W and N15/sup 0/E respectively. Paleoslope is commonly taken as the normal to the mean of all fold axes, in this case, N84/sup 0/E. The directly measured paleoslope is N10/sup 0/E, a difference of 74/sup 0/ between the two methods. These data indicate that the commonly used normal to the mean is not an accurate indicator of paleoslope when all folds are considered. The normal to the mean of only those folds with upslope closure is a better indicator of paleoslope. Likely explanations for these results include: folding was initiated by a shear which did not act in the downslope direction, and/or some folds with downslope closure were emplaced as detached, freely sliding, sediment bodies, the final orientation of which may have been influenced by local topography.« less
  • Current goals of the U.S. Department of Energy’s Advanced Power Systems Initiatives include coal generation at 60% efficiency, which would require steam temperatures of up to 760°C. This temperature will require the construction of boiler and turbine components from austenitic stainless steels and nickel alloys. Many of the alloys being considered for use are primarily Cr2O3 forming alloys [1-4]. It is well known that the addition of a small amount of reactive elements, such as the rare earths elements Ce, La, and Y, can significantly improve the high temperature oxidation resistance of both iron- and nickel- base alloys. A listmore » of the benefits of the reactive element effect include: (i) slowing scale growth, (ii) enhancing scale adhesion; and (iii) stabilizing Cr2O3 formation at lower Cr levels. The incorporation of the reactive element can be made in the melt or through a surface infusion or surface coating. Surface modifications allow for the concentration of the reactive element at the surface where it can provide the most benefit. This paper will detail a Ce surface treatment developed at NETL that improves the high temperature oxidation resistance of Cr2O3 forming alloys. The treatment consists of painting, dip coating, or spraying the alloy surface with a slurry containing CeO2 and a halide activator followed by a thermal treatment in a mild (x10-3 Torr) vacuum. During treatment the CeO2 reacts with the alloy to for a thin CrCeO3-type scale on the alloy surface. Upon subsequent oxidation, scale growth occurs at a reduced rate on alloys in the surface treated condition compared to those in the untreated condition.« less
