Pierre shale
the Pierre shale was started in 1957 it was not the practice in laboratory F to photograph the spectra of standards on each plate along with the samples being determined. Although the advantages of in cluding the spectra of standards were recognized, no single set of standards was available that con ...There are also statistically significant differences between the Se levels when grouped by Pierre Shale type. These factors are considered when determining the forms of Se present and analyzing their chemistry using the reported thermodynamic relationships considering Ca 2+ , Mg 2+ , SeO₄ 2- , SeO₃ 2- and carbonates.whereas the underlying Cretaceous marine shale beds are rich in phosphorus, potassium, and iron. As a consequence, the Cretaceous strata are generally very poorly exposed beneath thick ground cover except along stream cut banks. In contrast, the White River beds form the steep upper hillsides of mostly barren white, red, and gray strata.

Shale sample size change is a fair response to a foreign fluid. Zhang et al. [87] conducted swelling measurements on Pierre I shale and Arco shale, demonstrating that adding salts (NaCl, KCl, and CaCl 2) can remarkably inhibit shale swelling. Higher salinity is more inhibitive, specifically given a salinity higher than the pore fluid and ...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.Pierre Shale. Blue-gray to dark-gray, fissile to blocky shale with persistent beds of bentonite, black organic shale, and light-brown chalky shale.

Pierre Shale - Jagged exposure of shale with red pigmentation along Rooney Road.The Pierre Shale is a geologic formation or series in the Upper Cretaceous which occurs east of the Rocky Mountains in the Great Plains, from Pembina Valley in Canada [2] to New Mexico . The Pierre Shale was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia). 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 ...These hills, however, are erosional remnants of the once much more extensive Pierre Shale rock formation.

The thickness of the Laramie-Fox Hills aquifer ranges from 0 to about 300 feet . The Laramie-Fox Hills aquifer generally consists of beds of fine- to very fine-grained sandstone or siltstone interbedded with shale. In Hell Creek Formation - dark colored continen 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.
