The study of modern sediments such as sand, silt and clay, and of the processes that form, transport, deposit and finally alter them. Sedimentary rocks cover up to three quarters of Earth's surface, record much of its history and harbor the fossil record, and the discipline works by comparison: a modern sand dune set beside an ancient aeolian sandstone tells a geologist how the old rock formed.

Facts
Central QuestionHow do modern sediments form, travel and come to rest, and what do sedimentary rocks record of Earth's history? 1 ScopeSedimentology studies the processes that produce, transport and deposit sediment, and the resulting sedimentary rocks, to reconstruct the environments in which they formed. 1 SignificanceSedimentology guides the exploration of oil, gas and groundwater reservoirs, which are commonly held in porous sedimentary rock. 1 Sedimentology
