Pierre shale.

The test was conducted in Cretaceous-age Pierre Shale in central South Dakota, USA. The shale at the site is saturated, has a permeability of 10-20 to 10-21?m 2, and is 70-80% clay, of which ...With imbibition experiments with Pierre shale cores, Wang, Butler, Liu, and Ahmed (2011) showed that LSW did not cause a permeability reduction in the presence of clays. ... Shale pieces #1–10 were used for Case 1, #11–20 for Case 2, and #21–30 for Case 3. For each core assembly, the longitudinal fracture was called “propped fracture ...Abstract. The purpose of this reconnaissance is to assess the potential of the Pierre Shale, of Late Cretaceous age, as a possible isolation medium for radioactive wastes. The regional …Near the entrance of the park, thick exposures of dark gray/black Pierre Shale can be seen. There are several yellow/white volcanic ash (bentonite) layers within the shale. In some locations along the river, the Crow Creek Member of the Pierre Shale (bright white and ~10 feet thick) can be seen.

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 ...Se-rich soils in eastern Montana, western North Dakota, much of South Dakota, Wyoming, Colorado, and Utah, are underlain by a mixture of rock types, but shale is abundant in these areas. Particularly high concentrations of Se occur in soils overlying the Northern Rolling Pierre Shale Plains (USDA, 2006) in central South Dakota.

The Sharon Springs Member of the Pierre Shale is stratigraphically unique. It differs from the rest of the Pierre Shale because of its dark color, resis­ tance to erosion, richness in organic material, and high radioactivity. At most localities, many ben- tonite beds are in the lower part of the member, andThe lower Pierre Shale consists primarily of the Sharon Springs Formation, which has been correlated regionally throughout Kansas, Colorado, Nebraska, Wyoming, South Dakota, and North Dakota.

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.

The Pierre Shale is the uppermost formation in the Cretaceous succession of northeastern . Nebraska. It overlies the Niobrara Formation and it is present under a small part of northwestern Cedar .

The Pierre shale outcrops in the northern portion of Sioux and Dawes counties, as shown in Pl. XI.

Origin of the Western Interior Seaway. During the Cretaceous period, the ancient Farallon and Kula tectonic plates were in the process of subducting beneath the North American Plate. This caused the overlying land to warp and form a large back-arc basin. Ocean waters began to fill in the basin during a series of sea level increases (or ...
