The following is a list of rock types recognized by geologists. There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. Additionally, different classification systems exist for each major type of rock.

Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering.Rocks like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay-like layers (strata).They are usually brown to gray in color and may have fossils and water or wind marks.

This diagram shows a selection of rock layers, or stratigraphic columns, from the Koobi Fora geologic formation on the eastern shore of Lake Turkana in Kenya. This area is a ridge of sedimentary rock where researchers have found more than 10,000 fossils, both human and other hominins, since 1968. These fossils aid the scientific investigation of human evolution.
