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.
