Bituminous shale

From Wikipedia, the free encyclopedia

Bituminous shale is an argillaceous shale impregnated with bitumen, often accompanying coal. It may contain kerogen; in that case it is classified as oil shale. When carbonaceous material is present in large amounts, bituminous shale grades into bituminous coal.[1] The term 'bituminous shale' sometimes is used in the broader context including also oil shales, albertite and other similar sedimentary rocks.

Uses

Bituminous shale may be used as fuel or as a paving material. It was used in pre-Roman times in the Kimmeridge Bay area of Dorset, England as a low-grade fuel and as a material for craftsmen. In Roman times, the first large-scale usage of bituminous shale was started. In 1851, a process for extraction of kerosene from bituminous shale was patented by Canadian physician and geologist Abraham Pineo Gesner.[1]
