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 Mancos Shale is a sample taken from outcrop. The Pierre Shale was recovered from a drill hole in a clay pit. The Opalinus Clay was taken from a borehole drilled at the Mont Terri underground research laboratory. [32] These samples were selected because preserved material was available for Pierre Shale and Opalinus Clay.Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time. Shale is a sedimentary rock.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 ...

With few exceptions the members of the Pierre shale, with respect to geographic location, are as follows: KANSAS SOUTH WYOMING NORTH COLORADO DAKOTA DAKOTA (Pueblo area)Pierre Shale of this area consists of a basal unit about 80 feet thick of moderately hard dark organic-rich shale containing numerous beds of bentonite. These beds are overlain by about 50 feet of lighter colored calcareous and bentonitic shale that slumps extensively. The cal­A.) True B.)

A.)In a broad sense, "nautiloid" refers to a major cephalopod subclass or collection of subclasses ( Nautiloidea sensu lato ). Nautiloids are typically considered one of three main groups of cephalopods, along with the extinct ammonoids (ammonites) and living coleoids (such as squid, octopus, and kin). While ammonoids and coleoids are monophyletic ...

One major culprit is the pierre shale that underlies the prairie east of the Rocky Mountains from Canada to Mexico. As people have populated, farmed, paved, drilled and built in the South Platte ...The Pierre shale has been stated to contain 70-80% clay, of which about 80% is mixed-layer smectite-illite (Neuzil 1993). Our first steps involve characterizing porosity and permeability of shale ... ….

The Sharon Springs Member of the Pierre Shale (lower Campanian) is a black, organically rich shale deposited in the Western lnterior Seaway during the Claggett Cyclothem. Atmospheric and water ...Yes, Pierre Shale bone preservation is generally known to be crappy and infiltrated with gypsum. Not coated, but infiltrated all throughout the bones. But I have never seen any oil/tar or other blatant hydrocarbons in the Wyoming or South Dakota materials I have collected or worked on. You can do a quick test for oil in the fossil by sniffing ...

Outcrop Pierre Shale is prepared for test by an initial drainage stage, in order to reduce the chemical potential of the pore water to a value more representative of buried rock. This enhances swelling when the shale is subsequently placed in contact with deionised water. Unlike vapour phase equilibration of chemical potentials, the stresses ...Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time. Shale is a sedimentary rock.Another heteromorph ammonite, Didymoceras nebrascense Meek and Hayden 1856, has been collected from the overlying Pierre Shale in western Kansas (Kennedy, et al., 2000). Internal molds of Clioscaphites vermiformis Meek and Hayden (1862) and C. choteauensis Cobban (1951) also occur in the middle Santonian Smoky Hill Chalk, and are used as ...
