It is in these rocks that the most diverse assemblage of fossils ever found in the Pierre Shale in North Dakota is located. In this part of eastern North Dakota the landscape has mostly been sculpted by glacial processes.Pierre Shale (generally a smectitic clay shale in this area). In the area of concern, Pierre Shale beds approximately 2.1 km thick dip steeply eastward (greater than 45°) as a result of regional uplift and, except where locally covered by alluvial deposits, crop out for at least 2.4 km in an easterly

Middle part of Bearpaw includes bentonite beds V, W, and X and is equivalent to Monument Hill bentonitic member of Pierre shale of the Black Hills.The Dissertation Committee for Talal Mohammad AL-Bazali Certifies that this is the approved version of the following dissertation: EXPERIMENTAL STUDY OF THE MEMBRANE BEHAVIOR OF

Mowry Shale. According to Keefer and Johnson (1997), the Mowry Shale in the Wind River Basin is characterized by two distinct units (fig. 5). The lower part consists of 50 to 150 ft of soft fissile clay-rich shale that has been referred to as the Shell Creek Shale in the adjacent Bighorn and Powder River Basins (Eicher, 1962;

The Pierre shale sample was extracted from blocks obtained from a Colorado quarry (Cerasi et al., 2017), and further cored to make cylindrical plugs from which fragments were detached and stored in air at room temperature. The sample was glued onto a pin and mounted on a goniometer head with its bedding-plane normal essentially co-aligned with ...Laboratory characterisation of rock properties is an important part of any resource evaluation and for shale gas, specific properties of importance include silt content, organic matter abundance and type, static and dynamic mechanical properties (brittleness), micro/macro-fabrics, porosity, permeability, petrophysical properties and anisotropy. ...The Campanian methane cold-seeps of the Pierre Shale, South Dakota yielded low numbers of foraminifera.

The Sharon Springs Member of the Pierre Shale contains some of the most organic-rich sediments deposited in the Western Interior Cretaceous Seaway. Typically, organic carbon ranges from 2 to 11 weight percent while maturity of the source rock varies from immature to over-mature across the basin. Previous researchers variously ascribe the origin ...Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens.Based on their deposition environment, oil shales are classified as marine, …

To stimulate pyrite oxidation in the selected shale samples, a soxhlet extractor was modified to continually drip distilled water over the shale chips contained within a cellulose thimble, before being collected in a flask, in a setup suggested by Pedro (1961) (Fig. 1).The condenser was left open, allowing exchange with the atmosphere; no attempt was made to control/monitor oxygen and carbon ...Attenuation measurements were made near Limon, Colorado, where the Pierre shale is unusually uniform from depths of less than 100 ft to approximately 4,000 ft.

Particle velocity …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. But whether osmosis can have a significant ...PIERRE SERIES The Pierre series consists of moderately deep, well drained soils formed in clayey residuum, or local alluvium over residuum, derived from shale bedrock.

[Age is Pliocene.] Source: US geologic names lexicon (USGS Bull. 1200, p. 2803-2804).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 ...The Sharon Springs Member of the Pierre Shale has recently been divided and reclassified as the Gammon Ferruginous Formation and Sharon Springs Formation, with the Pierre Shale being upgraded to group status.
