Litologie
Litologie (z řeckého lithos, kámen a logos slovo) byla původně obecná nauka o horninách.[1] Dnes tento termín označuje především vědu, která se zabývá zkoumáním a popisem usazených hornin. Jde tedy o petrografii sedimentů neboli všeobecnou sedimentologii,[1] tedy o popis vlastností hornin, [2] které lze pozorovat prostým okem. Patří sem mimo jiné vyhodnocování stavby horniny, její zrnitost, vrstevnatost, barva a podobně. Tento popis pak slouží k jejich rozdělení do jednotlivých litostratigrafických jednotek pro účely geologického mapování.

The Permian (bottom) through Jurassic (top) stratigraphy of the Colorado Plateau area of southeastern Utah that makes up much of the famous prominent rock formations in protected areas such as Capitol Reef National Park and Canyonlands National Park. From top to bottom: Rounded tan domes of the Navajo Sandstone, layered red Kayenta Formation, cliff-forming, vertically-jointed, red Wingate Sandstone, slope-forming, purplish Chinle Formation, layered, lighter-red Moenkopi Formation, and white, layered Cutler Formation sandstone. Picture from Glen Canyon National Recreation Area, Utah.
