It and its equivalents extend more than 2000 km from northwestern New Mexico, USA into Alberta and Saskatchewan, Canada.The geological result of 30 million years of oceanic existence is the Pierre Shale, a marine deposit of 8,000 feet of hardened ocean-bottom ooze and mud, the thickest geological formation in the Denver region. For all that, the exposure at Rooney Road is only about a thousand feet. Viewed from the road, the layers of ocean floor appear nearly ...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 OFEconomic 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.Cross section of Pierre Shale in the study area showing location of boreholes 87-1, 2, 3 and 88-1, 2.

The host medium for Neuzil's (2000) in situ experiment, the Cretaceous Pierre Shale, is a low-permeability claystone found over much of central North America. It and its equivalents extend more than 2000 km from northwestern New Mexico, USA into Alberta and Saskatchewan, Canada.Near the entrance of the park, thick exposures of dark gray/black Pierre Shale can be seen. There are several yellow/white volcanic ash (bentonite) layers within the shale. In some locations along the river, the Crow Creek Member of the Pierre Shale (bright white and ~10 feet thick) can be seen.A suite of siltstone samples from the Upper Cretaceous Pierre Shale from the contact zone of a 130-cm thick igneous dike near Wolcott, Colorado, U.S.A., was taken from the contact to 170 cm from ...SUMMARY. The viscoelasticity of subsurface media is succinctly represented in the generalized wave equation by a fractional time derivative. This generalized viscoelastic wave equation is characterized by the viscoelastic parameter and the viscoelastic velocity, but these parameters are not well formulated and therefore …A historical collection of hesperornithiform fossils from the Gammon Ferruginous, Pembina, and Millwood members of the Pierre Shale (Campanian, Upper Cretaceous) in southern Manitoba, Canada, was examined to revise their taxonomy. Only two species of Hesperornis have been recognized in previous studies on the Pierre Shale in Manitoba, but our study recognizes six species of two genera ...

The marine Pierre shale, of Late Cretaceous age, on the northern and western flanks of the Black Hills, consists of dark gray shale with some sandy shale and sandstone, and many beds of bentonite. It ranges in thickness from 2,000 to 2,700 feet.

The Upper Cretaceous carbonate-rich Niobrara Formation is a prominent petroliferous unconventional reservoir that is generally characterized by fine-scale heterogeneities that complicate local and regional correlation of target zones, well placement and completion strategies. Within rhythmically interbedded reservoirs like the Niobrara Formation, the occurrence of thin marl and chalk beds ...

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.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.

Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). Generally, shale occurs in thin layers or beds and represent low-energy environments such as: offshore deposits of mud in ancient seas, in ...The thick Pierre shale was also bent upward under the present site of Boulder. Active mountain building continued throughout the remainder of Tertiary and Quaternary time. It is probable that the Rockies attained their greatest height in the early Tertiary Period, about 45 million years ago. Those peaks were later lowered by erosion.Pierre Shale--Upper unit Granitic rocks of 1400-m.y. age group (Middle Proterozoic) at surface, covers 0.9 % of this area Includes Silver Plume, Sherman, Cripple Creek, St. Kevin, Vernal Mesa, Curecanti, Eolus, and Trimble Granites or Quartz Monzonites; also, San Isabel Granite of Boyer (1962) and unnamed granitic rocksBrule Formation.
