Scale dependence also has been detected in lacustrine clay [Ru- dolph eta!., 1991] and clay till [Keller et al., 1988] and isThe Sharon Springs Member of the Pierre Shale, usually described as a stagnant-basin deposit, shares more features in common with upwelling zones than with stratified stagnant basins. Specifically, the overall facies distribution of the Sharon Springs includes a basin-ward zone of laminated, highly organic-rich strata bounded on the west by ...

The Pierre shale underlies all of Thomas County at relatively shallow depths and serves as an impervious floor below the water-bearing sediments. It retards the downward percolation of water in much the same manner as the floor of a tank. Although the thickness of the Pierre shale below all parts of the county is not known, it is probably ...

The regional stratigraphic and structural setting of the Pierre Shale in the northern Great Plains is summarized from subsurface data.Undrained as well as drained tests were performed with samples of Pierre outcrop shale, which has variation in porosity (19-26%) and clay content (40-60%) between different batches. Fig. 13 shows the resulting total axial stress vs. axial strain curves for two Pierre Shale samples drilled perpendicular to bedding. The undrained test ...In the higher heat flow areas in western Colorado, temperatures increase rapidly in the Pierre Shale, 40°C/km (2.2°F/100 feet) or higher, and then much less rapidly in underlying layers, 20°C/km (1.1°F/100 feet). Thermal wells may be pumping water from depth at the ambient temperature of the water under these regional temperature conditions.

The test consisted of obtaining multiple two cubic-inch samples of unweathered Pierre Shale and placing them on a filter in a vacuum chamber. Samples were vacuumed at 24 inch Hg ...

This paper presents a comprehensive methodology for analysing the compression and consolidation behaviour of shales. An apparatus was designed to perform oedometric high-pressure tests by applying a maximum vertical total stress of 100 MPa and simultaneously controlling the pore water pressure of the specimen.

Pierre soils are on gently sloping to rolling hillslopes on uplands on the Pierre Shale Plains (MLRA 60A). Saturated hydraulic conductivity is low. Slopes range from 0 to 30 percent.Baptornis ("diving bird") is a genus of flightless, aquatic birds from the Late Cretaceous, some 87-80 million years ago (roughly mid-Coniacian to mid-Campanian faunal stages).The fossils of Baptornis advenus, the type species, were discovered in Kansas, which at its time was mostly covered by the Western Interior Seaway, a shallow shelf sea.It is now known …Water saturation, organic matter content, and fractures are important factors influencing the physical properties of shale. In this study, shale samples were subjected to heating at 1 °C/min and then gradual cooling. An initial suite of tests was conducted at temperatures of 100 °C, 200 °C, 300 °C, 400 °C and 500 °C. The P-wave and S-wave velocities were measured, rock mechanics ...Pteranodon lived in North America. Its fossils specimens were found in the Niobrara Formation and Pierre Shale Formation in Kansas, Alabama, Nebraska, Wyoming, and South Dakota. What was a Pteranodon's habitat?
