terms:oil_shale
The term applied to several kinds of organic and bituminous shales, most of which consist of varying mixtures of organic matter with marlstones, shale, and clay. The organic matter is chiefly in the form of a mineraloid, called kerogen. Oil shales are widely distributed throughout the world and become of economic interest because of the large amounts of oil which can be obtained from them. See kerogen.
