The Chagrin Shale is a gray shale that begins thin and deep underground in north-central Ohio. As it proceeds east, the formation thickens, rises to the surface, and contains greater amounts of siltstone.

Oil shale geology is a branch of geologic sciences which studies the formation and composition of oil shales–fine-grained sedimentary rocks containing significant amounts of kerogen, and belonging to the group of sapropel fuels. Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Sheffield emerged as a shale statesman, encouraging the U.S. to lift a 40-year ban on exports of U.S. crude oil and snatching up rivals while publicly warning of a coming consolidation.

The Marcellus formation is a part of the ancient sedimentary system known as the Appalachian basin. The organic-rich black shale of the Marcellus formation was deposited in a foreland basin roughly paralleling the structural front of the present-day Appalachian Mountains during the Middle Devonian time about 390 million years ago (Harper, 1999).

Squeezing oil from Permian shale could get harder and more expensive in the years ahead for those who run out of higher-quality source rock.

Shale is a rock composed mainly of clay-size mineral grains. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...

Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its … See moreOil Shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material.
