Maximum length of specimen is approximately 8.5 cm.We have numerically modeled evolving fluid pressures and concentrations from a nine-year in situ osmosis experiment in the Pierre Shale, South Dakota. These data were obtained and recently interpreted by one of us (C.E.N.) as indicating a potentially significant role for chemical osmosis in media like the Pierre Shale. That analysis considered only the final pressure differentials among ...

The modeling uses the Fourier method to compute the spatial derivatives, and therefore can handle complex geometries and general material-property variability. I verified the results by comparison with the 2D analytical solution obtained for wave propagation in homogeneous Pierre Shale.Mowry Shale. According to Keefer and Johnson (1997), the Mowry Shale in the Wind River Basin is characterized by two distinct units (fig. 5). The lower part consists of 50 to 150 ft of soft fissile clay-rich shale that has been referred to as the Shell Creek Shale in the adjacent Bighorn and Powder River Basins (Eicher, 1962;Sharon Springs shale member of Pierre shale. Basal member of Pierre shale in Wallace County, northwestern Kansas, and its lithology differs widely from that of rest of formation. Upper 65 feet consists of flaky, somewhat bituminous black shale and, rarely, porous light-gray shale, both with abundant fish scales, gigantic septarian and smaller ...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 ...This paper describes the cranial morphology of two undescribed specimens of the polycotylid plesiosaur Dolichorhynchops bonneri from the Pierre Shale of South Dakota. Based on the axial osteology of the juvenile specimen (UNSM 55810), it was most likely a neonate at the time of death. The juvenile material exhibits well-defined suture lines in its …

Most of the Pierre Shale exposures in East-central North Dakota are of the DeGrey Member. The most obvious feature of this member is a large amount of iron manganese carbonate concretions. The few fossils I find in the Pierre here are usually in these worn concretions. The first fossils I found didn't come from the Pierre at all but came from ...

Originally referred to Dolichorhynchops osborni, the material was almost immediately christened Trinacromerum bonneri Adams 1997; more recently the material has been referred toPolycotylus.Results of a nine-year in situ measurement of fluid pressures and solute concentrations in shale are reported that are consistent with the generation of large (up to 20 MPa) osmotic-pressure anomalies which could persist for tens of millions of years. Osmotic pressures are generated by differences in chemical potential of a solution across a membrane. But whether osmosis can have a significant ...A suite of siltstone samples from the Upper Cretaceous Pierre Shale from the contact zone of a 130-cm thick igneous dike near Wolcott, Colorado, U.S.A., was taken from the contact to 170 cm from ...Nebraska Gov.

As a result of this natural insulating effect, temperature gradients in carbonaceous strata may become elevated even under conditions of low to average heat flow, causing underlying rocks to reach higher temperatures and higher thermal maturities than would otherwise occur.Pierre Shale in the northern Great Plains (Shurr, 1977; 1980).
