entry pressure and, therefore, the shale's seal capacity. Measured capillary entry pressures were also used to estimate the pore throat radius of shales.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 ...Dolichorhynchops is an extinct genus of polycotylid plesiosaur from the Late Cretaceous (early Turonian to late Campanian stage) of North America, containing three species, D. osborni, D. bonneri and D. tropicensis, as well as a questionably referred fourth species, D. herschelensis. Dolichorhynchops was a prehistoric marine reptile, but at least one …Shales play a major role in the stability of slopes, both natural and engineered. This paper attempts to provide a review of the state-of-the-art in shale slope stability. The complexities of shale terminology and classification are first reviewed followed by a brief discussion of the important physical and mechanical properties of relevance to shale slope stability. The varied mechanisms of ...

These data, in addition to new information from exploratory drilling/logging activities within the MEA, are used to describe the geology and seismology in this section. 2.6.1 Geology and Seismologywhereas the underlying Cretaceous marine shale beds are rich in phosphorus, potassium, and iron. As a consequence, the Cretaceous strata are generally very poorly exposed beneath thick ground cover except along stream cut banks. In contrast, the White River beds form the steep upper hillsides of mostly barren white, red, and gray strata.

The Hygiene member outcrops north of the Table Mountain north gate at Nelson Road. The Pierre Shale is an olive-gray shale with interbedded sandstone layers, locally with ironstone concretions and limestone concretions. The Pierre Shale formed in the shallow udeh Fox Hills Formation. The Fox Hills Formation is a Cretaceous geologic formation in the northwestern Great Plains of North America. It is present from Alberta on the north to Colorado in the south. Fossil remains of dinosaurs, including tyrannosaurs, as well as large marine reptiles, such as mosasaurs, have been recovered from the formation.Gomez-Gutierrez et al. (2011) conducted slake durability and swell tests on unweathered shales, and the prediction equation is written: (4) S = 29.33 exp ( − 0.064 I d 2 C) where Id2, which as a function of W, is the slake durability index. When shale underground absorbs water, the confined pressure will influence its swelling potential.
