MIXED-LAYER CLAY IN THE PIERRE SHALE AND EQUIVALENT ROCKS, NORTHERN GREAT PLAINS REGION By LEONARD G. SCHULTZ ABSTRACT Mixed-layer illite-smectite is the most abundant constituent in much of the Pierre Shale and equivalent rocks. X-ray diffraction data on both peak positions and intensities have been used to distinguish illite- beidellite- andCited by: The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine sediments; and in the area between, both types of rock are separated by.

Geological Origin of Clay Clay is a mineral 'stew' that is the result of the erosion of the earth's crust over vast spans of time. What was originally the mineral feldspar in igneous rocks, primarily granite, breaks down over time and becomes the microscopically fine-particled clay that we form with our bare hands.

A reservoir rock is a place that oil migrates to and is held underground. A cap rock is a layer of hand, impervious rock overlying and often reeling in a deposit of oil, gas, or coal.
The mineralogy, δO 18, and δD of the Mixed-layer illite/smectite (I/S) is the dominant mineral in the bulk bentonite and usually the only mineral in the. This formation is a Late Cretaceous marine clay-shale composed predominantly of fluvial mixed-layer illite/smectite and quartz.
During deposition of the shale, periodic and explosive volcanism generated thin beds of bentonite, consisting initially of volcanic ash and subsequently altered to.
Cretaceous rocks of Kansas are confined to the Great Plains physiographic province which, in the part of the state described in this guidebook, is divided into two contrasting sections, the Smoky Hills to the east and the High Plains to the west (figure 1).
West of the Fort Hays escarpment the High Plains section is underlain by Pierre. The mixed-layer clay is usually randomly stacked (R0), containing 20 to 60% illite layers.

Geol. Surv. Prof. Pap. The Mancos Shale or Mancos Group is a Late Cretaceous (Upper Cretaceous) geologic formation of the Western United States. The Mancos Shale was first described by Cross and Purington in  and was named for exposures near the town of Mancos, Colorado.
Clay mud, from the chemical breakdown of feldspars and ferromagnesian minerals in igneous, metamorphic and immature sedimentary rocks, and from reworked clay-bearing sedimentary rocks Dissolved calcite (calcium carbonate, CaCO 3, AKA lime), derived from calcium (Ca) weathered from common feldspars, and from reworked lime-bearing sedimentary rocks.
The Pierre shale forms the surface rock over most of the eastern half of North Dakota and South Dakota but its outcrop narrows toward the Black Hills due to the Tertiary overlap. Downdip from the outcrop it is everywhere found in the subsurface of both the Dakotas. The Pierre is dark to gray, uniform gumbo shale with several calcareous zones in.
The base of the overlying Pierre Shale is composed of the Burning Brule Member within the Sharon Springs Formation, the former of which is up to 24 m thick (Bertog, ).
The Burning Brule Member is a particularly organic-rich unit that has produced underground fires, likely due to the oxidation of pyrite, and in the study area, it varies from. Road-cut exposures commonly exhibit multiple cleavage directions and calcite veining.
Sevier Shale include relatively large amounts of organic material, thus acting as a potential hydrocarbon source rock in some parts of the region. Its fine-grained texture and low permeability allow this rock to form a good reservoir cap rock. Near Kremmling the Pierre Shale has been correlated with the Pierre Shale east of the Front Range, Colorado based on fossil evidence (Izett et al., ).
Maps of the Pierre Shale surrounding Kremmling were created by Hail () and Izett () and show the extent of the Pierre outcrops in the region (Figure 4) (Izett et al., ).
Shale is a soft, finely stratified sedimentary rock that formed from consolidated mud rich in clay minerals and can be split easily into fragile plates, such as along bedding plains (Figure ).
Shale forms from the compaction of sediment dominated by clays. Clays are composed of any microscopic mineral particles. Most dust is clay sized.Clark, D. L.
