Shale deposits
Black shale is a dark-colored mudrock containing organic matter that may have generated hydrocarbons in the subsurface or that may yield hydrocarbons by pyrolysis. Many black shale units are enriched in metals severalfold above expected amounts in ordinary shale. Some black shale units have served as host rocks for syngenetic metal deposits.Black …Numerous deposits of oil shale, ranging from Precambrian to Tertiary age, are present in the United States. The two most important deposits are in the Eocene Green River …

According to some workers, this part of the Raghavapuram Shale represents the deposit of an estuarine valley fill, deposited in lowstand tract. An incised valley carved out earlier in the underlying unit was filled back by sediments during the Cenomanian–Turonian transgression (Chitra Rao and Asthana 2000 ).A series of 25 aquifer/shale separation maps show where the principal aquifers overlie a shale or clay unit. Each map shows a relative estimate of the vertical separation between the base of a given aquifer and the top surface of a given shale of clay below that aquifer. Basic interpretive information about the separation maps is also available.Shale gas in the United States is an available source of unconventional natural gas.Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas.Shale oil undergoes several refining processes before it can be used, including pyrolysis, hydrotreating, hydrocracking, and delayed cooking, transforming the oil into usable forms. Shale comes in three major categories – marine, lacustrine, and terrestrial – depending on the origin of the organic matter that makes up the shale deposits.Clay is sediments or rocks with greater than 67% clay-size (2 micrometers or less) or colloidal size particles.
