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 very same Pierre shale sample was measured using both home-laboratory attenuation-contrast µCT and synchrotron XRD-CT, see Fig. 1 for sketches of the setups and coordinate …The Pierre Shale consists of interbedded marine shale and sandstone representing nearly continuous marine sedimentation during Late Cretaceous time. The Pierre Shale and time-equivalent marine units in the western interior United States contain 28 ammonite range zones. The ammonites show such rapid evolution and such wide geographic extent that their range zones are useful for time-stratigraphic c

It overlies the Niobrara Formation and it is present under a small part of northwestern Cedar .It is very necessary for clay shale layer to slake for durability.

Several locations of clayshale ...The Pierre shale typically shows significantly higher tensile strength under induced swelling pressures which makes it more difficult to induce hydraulic fracture in reservoir shales. Previous studies have shown that higher concentrations of KCl increased the tensile strength of shales. 7 On the other hand, the lower tensile strength observed ...The remains of Elasmosaurus were located by Turner at McAllaster Butte in the 'middle' or 'organic-rich shale' unit of the Sharon Springs Member (Zone of Baculites asperformis, lower Middle Campanian) of the Pierre Shale, Logan County, Kansas (Gill, Cobban, and Shultz, 1972).The middle unit is about 27 m (90 ft.) thick and extends upward to within 3 m (10 ft.) of the contact with the ...Member of the Pierre Shale. Introduction The SUSG Project is a multi-year investigation of the shale-gas potential of the Late Cretaceous shale sequences of southwestern Manitoba. The formations included in this study are the Ashville, Favel, Carlile and Pierre Shale (Figure GS-13-1). The goal of the project is to gatherThe aquifer is underlain by the nearly impermeable Pierre Shale, which forms the base of the aquifer system. 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.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.Biofacies dynamics in the Upper Cretaceous Pierre Shale, Western Interior, USA .

Pierre Shale (70 Ma) As the shoreline progressed westward, Colorado became inundated by a shallow sea. Rivers from distant mountains brought large amounts of clay and silt to this sea where it was deposited. This is how the Pierre Shale formed. Scientists have estimated that the depth of the sea reached around 600 ft at its maximum depth.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 ...The lower Pierre Shale shows a broad range of TOC, allowing comparison of TOC stratigraphic trends with MSA and paleoenvironmental variation to determine the dominant influences on OM burial.

Abstract. Body-wave dispersion is documented for a three-dimensional case using the pulse propagation experiment in the Pierre Shale conducted by McDonal et al. (1958) and for a two-dimensional case using ultrasonic pulse propagation in a Plexiglas plate. The magnitude of the dispersion for a five-octave frequency band was only about two to ...The Pierre shale is exposed along the Missouri River for a dis- tance of about twenty miles north of the South Dakota line, or as far as the mouth of Big Beaver Creek in Emmons County; in eastern Montana it appears along the Missouri Valley from a point probably as far west as the Musselshell River to the station ...…

The oldest formation is the Pierre Shale, these black layers were deposited between 69 and 75 million years ago during the Cretaceous Period when a shallow, inland sea stretched across what is now the Great Plains. Sediment filtered through the seawater, forming a black mud on the sea floor that has since hardened into shale.
