Stress-Strain behavior for a shale sample. Comparison between Athy's response (solid line), characterization using Athy's compaction curve (dotted line), and characterization using consolidation tests (three dashed lines), with parameters from: 1- Pierre Shale Deep (Table A1); 2- Fort Union Shale Deep (Table A1); 3- Lagunillas Clay …The Pierre shale sample was extracted from blocks obtained from a Colorado quarry (Cerasi et al., 2017), and further cored to make cylindrical plugs from which fragments were detached and stored in air at room temperature. The sample was glued onto a pin and mounted on a goniometer head with its bedding-plane normal essentially co-aligned with ...The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, collected borehole geophysical data and completed simple aquifer tests to estimate the thickness and hydraulic properties of surficial deposits. The purpose of data collection was to create generalized contour maps of Pierre Shale elevation and surficial deposit thickness within and near Ellsworth Air ...The Pierre shale contains many bentonite layers, particularly in the Sharon Springs unit which occurs widely from the Dakotas to Kansas (Gill et al., 1972). It was early recognized …

These rocks are conformably overlain by the Upper Cretaceous Pierre Shale, a body of open-marine shale as much as 2,900 ft thick.

Large baculite from previous image (center) seen in side canyon near its excavation location (slighly up and to left).The Cretaceous Pierre Shale formation of the United States and Canada is well known for the abundant ammonoid fauna it yields, including Baculites, Placenticeras, Scaphites, Hoploscaphites, and Jeletzkytes, as well as many uncoiled forms. Many of these also have much or all of the original shell, as well as the complete body chamber, still intact. Many …

Uncertainty about the origin of anomalous fluid pressures in certain geologic settings has caused researchers to take a second look at osmosis, or flow driven by chemical potential differences, as ...The Cretaceous shale bedrock is mainly the Pierre Shale and Niobrara Formations. This shale is relatively friable (i.e., low strength) and fluvial processes, coupled with freeze–thaw and wetting–drying cycles, quickly break down this material into fine-grained sediment.Attenuation measurements were made near Limon, Colorado, where the Pierre shale is unusually uniform from depths of less than 100 ft to approximately 4,000 ft. Particle velocity wave forms were measured at distances up to 750 ft from explosive and mechanical sources. Explosives gave a well‐defined compressional pulse which was observed along vertical and horizontal travel paths. A weight ... ….

These hills, however, are erosional remnants of the once much more extensive Pierre Shale rock formation. It is in these rocks that the most diverse assemblage of fossils ever found in the Pierre Shale in North Dakota is located. In this part of eastern North Dakota the landscape has mostly been sculpted by glacial processes.part of the region, and the Pierre shale of Cretaceous age, which underlies the Ogallala formation throughout the region, crops out in the more deeply incised valleys. Many parts of the upland area are underlain by dune sand, and the principal valleys are underlain by alluvium of Quaternary age. The Ogallala formation contains thick beds of ...The studies indicate that repeated uplift and subsidence may have been the cause of extensive faulting mapped in the Pierre Shale since its deposition in Cretaceous time. Surficial fault displacements that cause damage to engineered structures are thought to be the result of construction-induced rebound in the Pierre Shale, although tectonic ...

Mu extension cord to power strip Four case histories where important changes in pile capacity were observed with time are presented. Two show an increase of pile capacity for shaft bearing piles driven into deep sand deposits. The increase occurred over a period longer than needed for pore pressure dissipation.

The Vermejo Formation is an historically important coal-bearing formation. Mining began in 1870 in the rich Raton coal bed near the base of the Vermejo Formation. [5] The bed contained bituminous coals of coking quality. These were being extensively exploited by 1924 [4] but the beds were largely exhausted by 1965.the Pierre Shale on the reservation. The geology and methods of mining and processing this sub-economic mineral resource have been studied extensively; technologically, extraction of manga­ nese is possible.

NPS Photo. Pierre Shale. The "base" of the Niobrara NSR is Pierre Shale, a gray to black rock that is difficult to see in the western half of the river. Those who visit the eastern half of the river, which is much more difficult to float, may see dark bluffs of the rock.We validated our numerical results through comparisons with theoretical constant-Q attenuation and dispersion solutions, field measurements from the Pierre Shale, and results from 2D viscoacoustic analytical modeling for the homogeneous Pierre Shale. We also evaluated different formulations to show separated amplitude loss and …
