In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial environments.(Pinet, 79) Consisting of sand, mud, and silt carried to sea by rivers, their composition is usually related to their source rocks; deposition of these sediments is largely limited to the continental shelf.(Pinet, 79-83)

Sources of terrigenous sediments include volcanoes, weathering of rocks, wind-blown dust, grinding by glaciers, and sediment carried by icebergs.
