Oil shale despite the name does not actually contain oil but rather a type of organic matter called kerogen a precursor of oil that is converted to a type of crude oil when heated to about 450 – 500° C. The oil shale deposits are in three structural and sedimentary basins that have been recently assessed:

Oil shale is a sedimentary rock. As it reaches its oil window oil shale releases a liquid known as shale oil . Oil shale is the rock from which shale oil is extract ed. Shale oil is similar to petroleum and can be refined into many different substances including diesel fuel gasoline and liquid petroleum gas (LPG).
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced called shale oil .

Oil shale is commonly defined as a fine-grained sedimentary rock containing organic matter that yields substantial amounts of oil and combustible gas upon destructive distillation. Most of the organic matter is insoluble in ordinary organic solvents; therefore it must be decomposed by heating to release such materials.
There are six mineral (rock) categories of oil shale resources namely tasmanite marinate kukersite torbanite lamosite and cannel coal. As with coal oil shale can be characterized via proximate and ultimate analysis. Some typical results for oil shale analyses are tabulated in Table 3.10.
