The hydraulic barrier was simplified into a single unit with hydrogeologic characteristics representative of the Pierre Shale. The hydraulic barrier was assigned a diffusivity of 10 −8 m 2 /s in all model simulations based on parameters derived from a field scale osmosis study (Garavito et al., 2006 ) and adjusted for a temperature and ...However, Pierre shale, like most sedimentary rocks, can be taken to be transversely isotropic. Such a material has one set of properties in the plane of the bedding and a different set of properties normal to the plane of the bedding. In the present treatment, planes parallel to the x, xZ plane are taken as the plane of the bedding, and ...The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, used surface-geophysical methods to delineate the top of Cretaceous Pierre Shale along survey transects in selected areas east and southeast of Ellsworth Air Force Base, South Dakota, from April to September 2021. Two complementary geophysical methods—electrical resistivity and passive seismic—were ...The Pierre Shale is a massive formation that underlays many Front Range cities, Denver, and much of the eastern plain of Colorado. This unit was formed by the continued transgression of the interior seaway that flooded eastern Colorado during the Cretaceous period. Shale is formed in deep, calm marine water, and is basically mud and silt turned ...

The Pierre Shale was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia).

For example, the Pierre Shale formation can be recognized across the Great Plains, from New Mexico to North Dakota. The famous White Cliffs of Dover in southwest England can be matched to similar white cliffs in Denmark and Germany. A second clue could be the presence of a key bed, or a particularly distinctive layer of rock that can be ...

preconditioned in desiccators at different relative humidities. For both shale types, we present and discuss experimental results that demonstrate strong saturation and frequency dependence of dynamic Young's moduli, Poisson's ratios and Thomsen's anisotropy parameters, as well as P- and S-wave velocities at seismic and ultrasonic frequencies.

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.Underneath the Pierre Shale is the Dakota Sandstone, which is a source of water near the outcrop/subcrop areas on the western limb of the basin. In their respective outcrop areas, Denver Basin aquifers are unconfined (under water table conditions), whereas in the deeper parts of the basin, the aquifers become confined due to intervening layers ...22-Jul-2015 ...

Furthermore, the artificial origin of shale gives it a particular geochemical meaning.

The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineering Center, investigated the use of surface geophysical methods to delineate the top of the Cretaceous Pierre Shale along survey transects in selected areas within and near Ellsworth Air Force Base, South Dakota. Two complementary geophysical methods—electrical resistivity and passive seismic—were used along ...To stimulate pyrite oxidation in the selected shale samples, a soxhlet extractor was modified to continually drip distilled water over the shale chips contained within a cellulose thimble, before being collected in a flask, in a setup suggested by Pedro (1961) (Fig. 1).The condenser was left open, allowing exchange with the atmosphere; no attempt was made to control/monitor oxygen and carbon ...In general, the Pierre Shale and older Cretaceous rocks are exposed on the north side of the Arkansas River along the study reach (Fig. 2).The Pierre Shale and younger rocks are exposed on the south side of the Arkansas River, except at the downstream end where erosion has removed the overlying Pierre Shale and exposed the Niobrara Formation on both sides of the river.Garavito AM, Kooi H, Neuzil CE (2006) Numerical modeling of a long-term in situ chemical osmosis experiment in the Pierre Shale, South Dakota.

The Sharon Springs member of the Pierre shale of Cretaceous age, a hard black organic-rich shale similar to the Chattanooga shale, is radioactive throughout central and western South Dakota, most of Nebraska, northern Kansas, and northeastern Colorado. In the Missouri River valley, thin beds of the shale contain as much as 0.01 percent uranium.The depth to the Pierre Shale along the transects ranged from about 2.4 to 20.3 meters, and mean and median depths were about 9.2 and 9.0 meters, respectively.
