The Pierre Shale, which consists of an upper sandy member and a lower shaly member, is primarily marine in origin; however, the sandy member includes minor amounts of coal. Twelve ammonite range zones can be recognized in North Park, including ammonites as old as the early Campanian Baculites...

Global natural gas reserves in organic-rich, low-permeability shales are estimated at 716 trillion m 3 1. Natural gas extracted from these unconventional shale gas reservoirs is an important energy resource being developed in sev - eral countries and is under consideration in several others 2. However, animated public debate continues over pos-

LEFT: The specimen shown at left is from the Pierre Shale. It was found by Pam Everhart in 1995, and donated to the Sternberg Museum in 2004 (FHSM VP-15577). However, at least one specimen is known from the Smoky Hill Chalk in Gove County and is in the collection of the University of Kansas. RIGHT: FHSM VP-16466 is a new specimen collected in ...A geotechnical investigation of the Pierre Shale near Hayes, South Dakota, was conducted by the U.S. Geological Survey as a basis for evaluating problems in deep excavations into that formation.

Roads and structures built on Pierre Shale hillsides often slump as the shale becomes wet. The unit produces a variety of marine vertebrate fossils including fish, mosasaurs and plesiosaurs. Kn: Cretaceous, Niobrara Formation, 80-88 million years old The Niobrara Formation is composed predominantly of grey to yellow chalk and chalky shale.

Underneath the Pierre Shale is the Dakota Sandstone, which is a source of water near the outcrop/subcrop areas on the western limb of the basin. In their respective outcrop areas, Denver Basin aquifers are unconfined (under water table conditions), whereas in the deeper parts of the basin, the aquifers become confined due to intervening layers ...

of the Pierre Shale. Pelecypods the size of Inoceramus of the Pierre Shale are found today in shallow waters (Gill and Cobban, 1966). Descendants of other extinct fossil species from the Pierre Shale (some within the same genera as the fossils) occur today in shallow coastal waters of normal salinity (W. A. Cobban, oral commun., 1978).the Pierre Shale, Chadron Formation, and the Brule Formation at the CPF), also applies in a general sense to the MEA. 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 SeismologyThe Pierre Shale is a geologic formation or series in the Upper Cretaceous which occurs east of the Rocky Mountains from North Dakota to New Mexico. The Pierre Shale was described by …Pierre Shale. The "base" of the Niobrara NSR is Pierre Shale, a gray to black rock that is difficult to see in the western half of the river. Those who visit the eastern half of the river, which is much more difficult to float, may see dark bluffs of the rock. It is also visible if you drive to the intersection of Highway 7 and the river.The Pierre Shale Group is found in eastern South Dakota and western Wyoming in the United States of America. During the Cretaceous period, this area would have been part of the Western Interior Seaway, a marine environment. The Pierre is formed out of shale, sandstone, and bentonite. This group has been host to multiple fossil finds, including ...The Badlands of South Dakota show exposed rock layers that date from the Cretaceous Period (Pierre Shale) to the Eocene Epoch (Brule Formation sandstones) to the Oligocene Epoch (Sharps Formation sandstones).

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.

Northwest-sourced Riding Mountain sediments possess the highest ε Nd and lowest 87 Sr/ 86 Sr, closely resembling the composition of the Cretaceous Pierre Shale (Premo, 1992), though an influence of felsic- to intermediate-Proterozoic volcanic rocks of the Trans-Hudson orogen is also potentially consistent with this signature (Fig. 5). Superior ...

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;Pierre Shale up to the Raton Formation. However, Lee's focus in Berwind Canyon was on the coal-bearing Vermejo Forma-tion, so he presented very little information on the Pierre Shale in the canyon. Berry (2010, 2016, 2017, 2018a) has published studies of some of the ammonites and associated fossils in the Pierre Shale in Berwind Canyon.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.

Thickness up to 1,000 ft (305 m).Deposition began about 75 million years ago with the formation of the Pierre Shale, the base of the geologic formations in the park. Deposition ended about 28 million years ago with the Sharps Formation, the uppermost unit of Badlands stratigraphy. Erosion is the process of rocks gradually wearing away.Shale beds are abundant near base. Contains large flow casts about 20 ft above base. Contains fossil pelecypods in lower part of upper shale and at top of lower sandstone. Thickness 180 ft. Entire mapped formation is considered Pierre Shale by one [anonymous] authority.

Stratigraphers have determined that seven lithostratigraphic units are exposed in the study area: Chuar Group, Tremadoc Formation, Labrador Formation, Percha Shale, Salem Limestone, Paradox Formation, and Pierre Shale. The ages of the units have not yet been determined. To that end, fossils have been collected from nine stratigraphic horizons.The Pierre Shale is a dark gray clayey to silty mudstone that is exposed in large parts of the Northern Great Plains (Gill and Cobban 1966).It is time equivalent to the Bearpaw Shale in northern and western Montana, Alberta, Saskatchewan, and possibly Manitoba (depending on reference, e.g., Bamburak and Nicolas 2009).It is Campanian to Maastrichtian in age.5" Placenticeras Ammonite - Pierre Shale, SD.
