Pierre shale.

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 Dakota is a sedimentary geologic unit name of formation and group rank in Midwestern North America. The Dakota units are generally composed of sandstones, mudstones, clays, and shales deposited in the Mid-Cretaceous opening of the Western Interior Seaway. The usage of the name Dakota for this particular Albian-Cenomanian strata is exceptionally widespread; from British Columbia and Alberta ...The hydraulic barrier was simplified into a single unit with hydrogeologic characteristics representative of the Pierre Shale.

The lower Pierre Shale and the Niobrara Formation of the Powder River basin are examples of the “wide-shelf” configuration, in which subsidence is relatively slow, progradation is rapid, and sand is largely confined to the shelf. The regressive Lewis Shale of the Washakie and Red Desert basins illustrates the complex relations between a ...For the Pierre Shale specimens, the calculated temperatures of well-preserved jaw material match those of well-preserved shell material in the same individual. Analyses of the jaw elements in the Mooreville Chalk permit a comparison of the paleotemperatures between the two sites, and show that the Western Interior is warmer …Abstract.

The Pierre Shale has the highest CEC, approximately 40 meq/100 g, consistent with its large clay mineral content composed primarily of mixed layer illite/smectite. This value is consistent with the reported range of observed CEC values for the Pierre Shale in the literature (30-50 meq/100 g; Schultz et al., 1980). Samples GOM-14 and GOM-17 ...

The lack of histological work may be in part complicated by taphonomic processes in some of the more prolific hesperornithiform sedimentary units. For example, several members of the Pierre Shale are characterized by calcite crystallization in the preserved bones, destroying histological information.premium homes.
