Pierre Shale (Late Cretaceous) at surface, covers < 0.1 % of this area. Mostly medium to dark-gray, brownish-gray, and black, fissle clay shale. Locally grades to thin beds of calcareous, silty shale or claystone, marl, shaly sandstone, and sandy shale. Locally contains thin seams of gypsum and sparse selenite crystals. Approx. max thickness ...Sedimentary rocks rich in organic matter often have lower thermal conductivities than other rock types. As a result of this natural insulating effect, temperature gradients in carbonaceous strata may become elevated even under conditions of low to average heat flow, causing underlying rocks to reach higher temperatures and higher thermal maturities than would otherwise occur.Pierre Shale--Middle unit (Cretaceous) at surface, covers 2 % of this area. In Boulder-Fort Collins area, contains Richard, Larimer, Rocky Ridge, Terry, and Hygiene Sandstone Members; elsewhere shale between zones of Baculites reesidei and B. scotti.Stress-Strain behavior for a shale sample. Comparison between Athy's response (solid line), characterization using Athy's compaction curve (dotted line), and characterization using consolidation tests (three dashed lines), with parameters from: 1- Pierre Shale Deep (Table A1); 2- Fort Union Shale Deep (Table A1); 3- Lagunillas Clay …For Pierre Shale the calculation gives ρ 2 = 6.3 μm/s, while for sandstone a commonly cited literature value of approximately ρ 2 is 10–11 μm/s (Straley et al., 1997). Dunn et al. (2002) have shown that there is considerable variability of ρ 1 and ρ 2 in siliclastic rocks and our computed value is therefore reasonable. Interpretation of ...There were yellow crystals around the rock and also on the inside. The aammonites range from 1/4" to 2". The biggest bacculite is 4" long and 1" in diameter. The gastropods are very tiny, 1/4" or less. The bivalves are 1/8" to 6".

Measured capillary entry pressures were also used to estimate the pore throat radius of shales.The Pierre Shale, by far the thickest formation in the quadrangle, is easily eroded and poorly exposed, although a part of the Hygiene Sandstone Member, in the middle part of the formation, locally forms a hog­ back. The Pierre grades into the underlying Niobrara. A persistent ledge-forming limestone bed is regardedThe upper part of the Pierre Shale and Fox Hills Formation were deposited in the late Cretaceous (Maastrichtian) Western Interior Seaway. They crop out in a belt that roughly parallels the Front Range of the Rocky Mountains from Douglas to Weld County, Colorado. These rocks consist of sandy shales and sandstones and are overlain by the ...Water saturation, organic matter content, and fractures are important factors influencing the physical properties of shale. In this study, shale samples were subjected to heating at 1 °C/min and then gradual cooling. An initial suite of tests was conducted at temperatures of 100 °C, 200 °C, 300 °C, 400 °C and 500 °C. The P-wave and S-wave velocities were measured, rock mechanics ...The Pierre Shale is underlain by the Niobrara Formation throughout all of the northern Great Plains and the Niobrara is the target of exten­ sive recent exploration for natural gas. The Pierre is covered by units of Late Cretaceous, Tertiary, and Pleistocene age. It appears that theAbstract The purpose of this reconnaissance is to assess the potential of the Pierre Shale, of Late Cretaceous age, as a possible isolation medium for radioactive wastes. The regional stratigraphic and structural setting of the Pierre Shale in the northern Great Plains is summarized from subsurface data.For the Pierre Shale specimens, the calculated temperatures of well-preserved jaw material match those of well-preserved shell material in the same individual.

They reach up to 70 ft (21 m) high and include stunning ...The Pierre Shale at or near the surface displayed higher resistivity values than expected likely because of a greater degree of weathering, which reduces the quantity of conductive clay minerals and increases the resistivity. Many profiles in sheets 1-3 showed resistivity values greater than 30 ohm-m within 1 to 3 m of land surface where a ...Pierre Shale. Over the next 30 million years, the region was finally taken over by a deep sea, the Cretaceous Western Interior Seaway, and deposited mass amounts of shale over the area known as the Pierre Shale.
