The Niobrara Formation / ˌnaɪ.əˈbrærə /, also called the Niobrara Chalk, is a geologic formation in North America that was deposited between 87 and 82 million years ago during the Coniacian, Santonian, and Campanian stages of the Late Cretaceous.The Pierre Shale, by far the thickest formation in the quadrangle, is easily eroded and poorly exposed, although a part of the Hygiene Sandstone Member, in the middle part of the formation, locally forms a hog­ back. The Pierre grades into the underlying Niobrara. A persistent ledge-forming limestone bed is regardedThe Pierre Shale is a good target for electrical exploration because of the contrast between the relatively high resistivity sand/clay mix of the alluvium and the consistently low resistivity of the shale.

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 ...Pierre Shale. Mostly medium to dark-gray, brownish-gray, and black, fissle clay shale. Locally grades to thin beds of calcareous, silty shale or claystone, marl, shaly sandstone, and sandy shale. Locally contains thin seams of gypsum and sparse selenite crystals. Approx. max thickness 1970 ft.the saturation of the Pierre Shale. The vacuum-saturation strength testing procedure described in the standard was modified to allow for saturation of the soil samples. The test consisted of obtaining multiple two cubic-inch samples of unweathered Pierre Shale and placing them on a filter in a vacuum chamber. Samples were vacuumed at 24 inch Hg ...@article{osti_6131809, title = {Upwelling in Cretaceous western interior seaway}, author = {Parrish, J T and Gautier, D L}, abstractNote = {The Sharon Springs Member of the Pierre Shale, usually described as a stagnant-basin deposit, shares more features in common with upwelling zones than with stratified stagnant basins.

Some black shale contains organic compounds that can be converted to oil or natural gas. Other colors of shale are crushed and mixed with water to create clay.

The seep deposits appear as small mounds called "Tepee Buttes".Most of the Pierre Shale exposures in East-central North Dakota are of the DeGrey Member. The most obvious feature of this member is a large amount of iron manganese carbonate concretions. The few fossils I find in the Pierre here are usually in these worn concretions. The first fossils I found didn't come from the Pierre at all but came from ... ….

67) but it was suggested that this clay might be a weathering product of the underlying Cretaceous Pierre shale.

The objective of this study is to document the background biodiversity dynamics in a single lithofacies of the Upper Cretaceous Pierre Shale that was deposited in an offshore setting of the Western Interior Seaway (WIS) and to place these changes into an environmental context. To assess the background biodiversity dynamics, the concretionary ...Elevation range from 1,300 to 1,640 feet on the bottom land along the Missouri River to 1,640 to 2,950 feet on the shale plain uplands. Cretaceous Pierre Shale underlies almost all of this area. This is a marine sediment having layers of volcanic ash that has been altered to smectitic clays. These clays shrink as they dry and swell as they get wet.

These years were during the time of the dinosaurs, but since dinosaurs were land organisms, none is found in the shale.
