Chert is a fine-grained sedimentary rock composed of quartz (SiO2) that is microcrystalline or cryptocrystalline quartz. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits.

The Green River oil-shale deposits in western United States and a number of the Tertiary lacustrine deposits in eastern Queensland, Australia, are lamosites. Marinite is a gray to dark gray to black oil shale of marine origin in which the chief organic components are lamalginite and bituminite derived chiefly from marine phytoplankton . Here's the EIA's latest assessment of where the world's known technically recoverable shale oil and gas deposits are located.

Shale accounts for about 50% of all sedimentary rocks deposited on the.The Pierre Shale was deposited in a Late Cretaceous seaway which extended across North America from the Gulf Coast northward to the Arctic Ocean. Although connections are not preserved between the marine rocks in the western interior and those deposited north and south, the outline of the seaway isThe Utica Shale is much deeper than the Marcellus. The Utica Shale elevation map (shown as Figure 3 in the right column of this page) has contour lines that show the elevation of the base of the Utica Shale in feet below sea level. In some parts of Pennsylvania, the Utica Shale can be over two miles below sea level.

The Mancos shale is an Upper Cretaceous shale deposited 90–70 Ma in the Rocky Mountain area of western Colorado and eastern Utah and provides the source for many of the shale plays in the Rockies [Longman and Koepsell, 2005].

Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic …Shale. Shale is the most abundant of all sedimentary rocks. It is composed primarily of soft clay minerals, but may include variable amounts of organic matter, calcareous material, and quartz grains. Shale may be any color, but is generally greenish gray to grayish black.

There were three major past attempts to establish an American oil shale industry: the 1850s; in the years during and after World War I; and in the 1970s and early 1980s. Each time, the oil shale industry failed because of competition from cheaper petroleum .

A shallow ocean covered the surface most of this tropical geologic period of warmer climate. As marine organisms rich in calcium fell to the bottom of this ocean their remains became stone (lithification). k state football schedule 2023 Siltstone is deposited in a similar environment with shale, but is usually located near the old delta, lake or sea shore, where calm currents cause less particle suspension.
