Shale is a fine-grained sedimentary rock whose original constituents were clay minerals or muds. It is characterized by thin laminae breaking with an irregular curving fracture, often splintery and usually parallel to the often-indistinguishable bedding plane.... impregnated with bitumen
Bitumen
Bitumen is a mixture of organic compounds liquids that are highly viscous, black, sticky, entirely soluble in carbon disulfide, and composed primarily of highly condensed polycyclic aromatic hydrocarbons.... , often accompanying coal
Coal
Coal is a readily combustion black or brownish-black sedimentary rock. The harder forms, such as anthracite, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.... .

The fine-grained sedimentary rock known as oil shale contains significant amounts of kerogen , from which technology can extract liquid hydrocarbons....
Coal oil is a specific shale oil used for illuminating purposes. It is sometimes confused with kerosene or Oil lamp#Fuel, but coal oil is obtained from the destructive distillation of cannel coal, mineral wax, and bituminous shale, and hence called coal oil....
Bituminous rocks are sedimentary rocks, usually shale, sandstone, limestone or dolostone/dolomite, that contain traces of tar, bitumen, asphalt, petroleum or carbon....
