Pierre shale.

Term Pierre shale, rather than Mesaverde formation, used in northeast CO, Denver basin. Sandstones in the middle part of the Pierre--i.e., 2,400 to 3,100 ft above its base and about 5,275 ft below the top of the Pierre, are reassigned from Mesaverde, given formal stratigraphic rank, and designated (ascending order) Hygiene, Terry, Rocky Ridge ...and Niobrara) which consist of open-marine shale, limestone, and minor sandstone, and are 1,100-1,300 ft thick (Baltz, 1965; Woodward, 1984). These rocks are conformably overlain by the Upper Cretaceous Pierre Shale, a body of open-marine shale as much as 2,900 ft thick. Shale and siltstone in the upperPierre Shale. Pierre shale is the only formation of the Montana group present in Kansas. The formation is restricted to about the northwestern tenth of the state. Pierre shale has been subdivided into six members, but with exception of the basal member, Sharon Springs shale, they are not recognized in the subsurface. The Pierre is predominantly ...Detailed palynological analysis of depositional environments in carbonaceous shales and marlstones in the Cenomanian-Turonian (C-T) interval of the Cretaceous Western Interior seaway indicates that: (1) dinoflagellate species diversity, (2) ratio of Spiniferites to Cyclonephelium (S/C ratio), and (3) depositional organic facies are …

Pierre shale is of marine origin and was deposited in the Western Inland Seaway during the Cretaceous period. It is a geologic formation that occurs east of the Rocky Mountains from North Dakota to New Mexico and is about 700 feet thick, lying above the Niobrara formation. It is a dark-gray shale, that contains many fossils, and has veins and ...Sedimentary rocks rich in organic matter often have lower thermal conductivities than other rock types. As a result of this natural insulating effect, temperature gradients in carbonaceous strata may become elevated even under conditions of low to average heat flow, causing underlying rocks to reach higher temperatures and higher thermal maturities than would otherwise occur.

The Bearpaw Formation, also called the Bearpaw Shale, is a geologic formation of Late Cretaceous age.It outcrops in the U.S. state of Montana, as well as the Canadian provinces of Alberta and Saskatchewan, and was named for the Bear Paw Mountains in Montana. It includes a wide range of marine fossils, as well as the remains of a few dinosaurs.It is known for its fossil ammonites, some of which ...In particular, shales often show strong elastic anisotropy that originates from the alignment and platy nature of its constituent minerals, as underpinned by laboratory measurements provided by many authors (e.g., Lozovyi & Bauer, 2019; Szewczyk et al., 2018; Vernik & Nur, 1992; Wang, 2002b ).Pierre Shale, division of Upper Cretaceous rocks in the United States (the Cretaceous Period lasted from about 146 million to 65.5 million …Exposures of the Pierre Shale are very limited in southwestern North Dakota.

The Pierre Shale, one of the earliest described lithologic units of the Western Interior, was deposited during the late Cretaceous (Campanian and Maastrichtian stages) and is primarily a sequence of organic-rich black and grey shales and interbedded bentonites, most of which formed under relatively anoxic marine conditions (Crandell, 1952, Gill ...

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. Han et al., 2014), and (iii) Talvivaara/Terrafame Ni-Zn-Cu-Co ore in Finland ...

The Pierre Shale is underlain by the Niobrara Formation throughout all of the northern Great Plains and the Niobrara is the target of exten­ sive recent exploration for natural gas. The Pierre is covered by units of Late Cretaceous, Tertiary, and Pleistocene age. It appears that theThis is the Pierre Shale, which underlies much of the city of Colorado Springs and troubles engineering geologists with its expanding and contracting clay, which can crack foundations and heave roads. Two additional Cretaceous layers are on display along Popes Bluffs in Ute Valley Park.

It is located above the Niobrara neighborhood and below Fox Hills Bed. It is named after it occurred near Fort Pierre on the Missouri River in South Dakota. The Pierre Shale is of marine origin and was deposited in the Western Interior Seaway. This correlates with other marine ...Pierre Shale (Late Cretaceous) at surface, covers < 0.1 % of this area.

The depth to the Pierre Shale along the transects ranged from about 2.4 to 20.3 meters, and mean and median depths were about 9.2 and 9.0 meters, respectively. The elevation of the Pierre Shale and thickness of unconsolidated deposits generally increased with land-surface elevation from south to north; however, some transects displayed ...Sat, 04/12/2008 - 08:38 AM. The shale party is swelling. The latest shale play to cross my desk is Pioneer Natural Resources' Pierre play in the Raton Basin. Pioneer bought Denver's Evergreen Resources a few years back, and Evergreen had developed a very nice coalbed-methane business in the Raton Basin, mainly in the Vermejo and Raton coals.The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, collected borehole geophysical data and completed simple aquifer tests to estimate the thickness and hydraulic properties of surficial deposits.

For example, the Pierre Shale formation can be recognized across the Great Plains, from New Mexico to North Dakota.

Fossils in the Cody Shale and similar black shales of the intermountain west (e.g. Pierre Shale) are generally found in concretions. The concretions from this Casper site, called "27th and McKinley", have produced numerous inoceramids and some baculites, but fossils at this site are also found in the shale itself.

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 wave forms were measured at distances up to 750 ft from explosive and mechanical sources. Explosives gave a well-defined compressional pulse which was observed along ...In Pierre shale and Bakken cores with thicknesses ranging from 0.65 to 5 mm, permeabilities were basically independent of flow rate, in agreement with expectations from the Darcy equation. Saline brine spontaneously entered into oil-saturated Pierre cores, yielding recovery values up to 41% of original oil in place (OOIP). ...Shale is very sensitive to wetting fluids, such as water, or to a loss of fluid from its pores (Lyu et al., 2015).

An example shows that the proposed wave equation describes the constant-Q attenuation and velocity dispersion behaviour observed in Pierre Shale. Finally, we consider a plane-layer model and the Marmousi model to show how the new ...Member of the Pierre Shale. Introduction The SUSG Project is a multi-year investigation of the shale-gas potential of the Late Cretaceous shale sequences of southwestern Manitoba. The formations included in this study are the Ashville, Favel, Carlile and Pierre Shale (Figure GS-13-1). The goal of the project is to gatherShales 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 ...The modeling uses the Fourier method to compute the spatial derivatives, and therefore can handle complex geometries and general material-property variability.
