This finding extends both the geographical and stratigraphic ranges of the species. In addition, R. cedarense new species is described from the Baculites baculus ...The Pierre Shale, Fox Hills Sandstone, and Laramie Formation yield as much as 300 gpm (gallons per minute) to artesian wells. The White River Group of Oligocene age generally yields about 30 gpm to wells but yields larger amounts in places where it is highly fractured. The Pliocene Ogallala Formation yields as much as 50 gpm to wells across the ...

entry pressure and, therefore, the shale's seal capacity. Measured capillary entry pressures were also used to estimate the pore throat radius of shales.Economic geology. The Vermejo Formation is an historically important coal-bearing formation. Mining began in 1870 in the rich Raton coal bed near the base of the Vermejo Formation. [5] The bed contained bituminous coals of coking quality. These were being extensively exploited by 1924 [4] but the beds were largely exhausted by 1965.

Two springs contacting the Pierre Shale have water types similar to this; however, sulfate is the dominant anion for the other two springs. In general, springs contacting the White River Group are shown to have better potential as alternative sources of water supply for the village of Red Shirt than springs contacting the Pierre Shale.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 ...

Geological Resources Division 12795 West Alameda Parkway Academy Place, Room 480 LakewoAlthough the isolated, round teeth had been found in many marine deposits around the world, the first Globidens to be described (G. alabamaensis, Gilmore, 1912) was found in the Mooreville Chalk of Alabama.Another species, Globidens dakotensis (Russell, 1975), was discovered in the Pierre Shale of South Dakota. A third, and very complete Globidens skeleton (including stomach contents) was ...For the Pierre Shale specimens, the calculated temperatures of well-preserved jaw material match those of well-preserved shell material in the same individual. Analyses of the jaw elements in the Mooreville Chalk permit a comparison of the paleotemperatures between the two sites, and show that the Western Interior is warmer …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 …This paper presents the evaluation of the stiffness and strength anisotropy of overconsolidated (OC) Bootlegger Cove Formation (BCF) clays at the Port of Alaska, formerly known as the Port of Anchorage. The stiffness and strength anisotropic material response was evaluated based on triaxial samples equipped with internal …

The Sharon Springs Member of the Pierre Shale is stratigraphically unique. It differs from the rest of the Pierre Shale because of its dark color, resis­ tance to erosion, richness in organic material, and high radioactivity. At most localities, many ben- tonite beds are in the lower part of the member, and

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 Pierre Shale formation, that lies above the Morrison formation, does contain marine fossils, and so lies the problem. How could Boulder be covered in water during the time of the Pierre shale, but have terrestrial dinosaurs roaming its lands just 64 million years before? My theory is that an in-land body of water covered Boulder during the ...on Pierre type I shale at T =6 5 j C. Note that the rate of pressure. transmission is the same as the pore fluid standard curve, i.e. KCl. does not in any way retard mud pressure penetration.Continental sedimentation reflects a complex interplay of tectonics and climate. A 2000-km transect from coastal California to the western Great Plains documents a major increase in sedimentation (ca. 16–6 Ma) coeval with deposition of the hemipelagic Monterey Formation along the California coast.Fossils in the Cody Shale and similar black shales of the intermountain west (e.g. Pierre Shale) are generally found in concretions. The concretions from this Casper site, called "27th and McKinley", have produced numerous inoceramids and some baculites, but fossils at this site are also found in the shale itself.Map showing outcrop of Pierre (Bearpaw) Shale, Fox Hills Sandstone, Hell Creek, Lance, and Fort Union Formations in the Williston and Powder River Basins of Montana (MT), Wyoming (WY), North ...

At most localities, many ben- tonite beds are in the lower part of the member, andThe Cretaceous shale bedrock is mainly the Pierre Shale and Niobrara Formations. This shale is relatively friable (i.e., low strength) and fluvial processes, coupled with freeze–thaw and wetting–drying cycles, quickly break down this material into fine-grained sediment.Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation. the most common production technology h as been surface mining, followed b y p rocessing in . above-ground retorts.The Pierre Shale, a member of the Montana Group, is extensively exposed throughout the Northern Great Plains and is well exposed along the Missouri River Trench in central South Dakota.The purpose of data collection was to create generalized contour maps of Pierre Shale elevation and surficial deposit thickness within and near Ellsworth Air Force Base (study area). Natural gamma and electromagnetic induction (EMI) data were collected to refine or determine surficial deposit thickness at selected wells. Additionally, data from ...Pierre Shale (Upper Cretaceous) at surface, covers < 0.1 % of this area. Blue-gray to dark-gray, fissile to blocky shale with persistent beds of bentonite, black organic shale, and light-brown chalky shale. Contains minor sandstone, conglomerate, and abundant carbonate and ferruginous concretions. Thickness up to 1,000 ft (305 m).

highest confining pressure for the Pierre shale was only 13.79 MPa (2000 psi) because of its softness and highly ductile behavior under high confining pre ssure.

The presence of petroleum on the east flank of the basin and the limited geographic distribution of effective source beds indicate that extensive (perhaps 100 mi or 160 km) lateral migration has occurred. Cretaceous oils in reservoirs in the Terry and Hygiene Sandstone Members of the Pierre Shale have probably undergone extensive vertical ...Abstract. 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 ...The Pierre Shale is a dark gray to black shale that covers much of the High Plains and extends from southern Colorado to central North Dakota. The Sharon Springs Member is a uraniferous organic member of the Pierre (Gautier and others, 1984). Landishighest confining pressure for the Pierre shale was only 13.79 MPa (2000 psi) because of its softness and highly ductile behavior under high confining pre ssure.In the higher heat flow areas in western Colorado, temperatures increase rapidly in the Pierre Shale, 40°C/km (2.2°F/100 feet) or higher, and then much less rapidly in underlying layers, 20°C/km (1.1°F/100 feet). Thermal wells may be pumping water from depth at the ambient temperature of the water under these regional temperature conditions.The sea's signature is ammonites, baculites, and clams, pearly fossils entombed in a fossil mud called the Pierre Shale. This shale is exposed in the gully below you. A jungle sprang up after the sea drained away about 65 million years ago. For a long time tree roots broke up the shale, and chemicals from decaying plants produced a yellow soil.

Mancos and Pierre Shale. As the sea level rose, it flooded most of the state, depositing the Mancos Shale in the west and the Pierre Shale in central and eastern Colorado. These layers have produced an incredible menagerie of fossils, including coiled, squid-like ammonites, oysters, snails, rare and delicate pterosaur bones, enormous teeth of ...
