Shale is a fine-grained sedimentary rock that is composed primarily of clay minerals, such as illite, kaolinite, or smectite. It has a layered appearance and a smooth, dense texture. Shale forms as a result of the compaction and cementation of mud or clay sediment over millions of years.

It is often found in association with other sedimentary rocks, such as sandstone or limestone, and can contain fossilised remains of marine organisms.

Shale is an important source of natural gas and petroleum, and is also used as a building material and in the production of cement.
