The Bearpaw Shale extends in a north-south band from central Alberta through Montana and is the physical equivalent of the upper part of the Pierre Shale in adjacent parts of the upper midcontinent (Cobban and Reeside, 1952). The fauna of the Bearpaw Shale includes a broad array of mollusks, including ammonite cephalopods to whichMost of the Pierre Shale exposures in East-central North Dakota are of the DeGrey Member. The most obvious feature of this member is a large amount of iron manganese carbonate concretions. The few fossils I find in the Pierre here are usually in these worn concretions. The first fossils I found didn't come from the Pierre at all but came from ...The land-fill is underlain by upland alluvial terrace deposits that overlie a thick and almost impermeable shale.

SEM photograph of Pierre type I shale after exposure to a silicate-based drilling fluid. The picture shows a silicate-"cake" of 10 μm thickness on the shale's surface. This cake prevents mud filtrate invasion and pressure penetration, and at the same time acts as a leaky membrane with high efficiency (typically 30-80%) that enables ...Abstract. 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 …The Pierre shale, which contains only the montmorillonite mineral in the clay frac-tion, has a PI of 126. 7. Seven pe1·cent lime held the pH at 12. 20 for almost an hour, but it only reduced the PI to 28. 2 (Table 2). Nine percent lime held the pH at 12. 30 for 24 hr, and the soil tested nonplastic.The Pierre Shale and some lignite beds are known to contain CH 4 (Pantano, 2012; Hendry et al., 2016), so the presence of elevated CH 4 concentrations in several of those high-Cl samples could indicate the CH 4 in those samples is from the lignite or shale (Fig. 9 D).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 ...

To the right of the gray Pierre Shale is another section of sandstones, these more tan with concretions present in some of the beds. This sandstone represents the lower Fox Hills. Cross-bedding is prominent in many of these beds as well as soft-sediment deformation. . To the extreme right, gray shale of the Pierre shale are again exposed. ...Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring 4.6 m (15 ft) from head to tail and 2.2–3.2 t (2.4–3.5 short …The lower Pierre Shale represents a time of significant changes in the Cretaceous Western Interior Seaway, resulting from a complex interplay of tectonic ... ….

The teeth at left came from the very top of the chalk, just below the contact with the Sharon Springs Member of the Pierre Shale. Compared to the teeth from S. falcatus and S. kaupi (above), these these teeth came from a much larger shark.

The Pierre Shale was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia). The elevated attention in respect to mineral processing in the past couple of decades has principally been focused on four black shale deposits: (i) Kupferschiefer Cu-Ag ore (Poland and Germany) (Borg et al., 2012), (ii) Ni-Mo-PGE polymetallic ore in Guizhou province and its extension in other districts (China) (T.

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, andA grouping of four bentonite beds, herein named the Government Draw Bentonite Beds, is identified as a stratigraphic marker within the Virgin Creek Member of the Pierre Shale. The beds are found west of Pierre, South Dakota, over an area of at least 130 mi2 (210 km2) where no other markers within the Virgin Creek Member have been identified. In this area, the Government Draw is a potential tool ne k state game radio station Pteranodon lived in North America. Its fossils specimens were found in the Niobrara Formation and Pierre Shale Formation in Kansas, Alabama, Nebraska, Wyoming, and South Dakota. What was a Pteranodon's habitat?

Many … oreilys peoria il Results of a nine-year in situ measurement of fluid pressures and solute concentrations in shale are reported that are consistent with the generation of large (up to 20 MPa) osmotic-pressure anomalies which could persist for tens of millions of years. Osmotic pressures are generated by differences in chemical potential of a solution across a membrane.
