oil shale | National Geographic Society

Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas.

Types of Sedimentary Rock - ThoughtCo

Oct 09, 2019· Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.
