Terrigenous sedimentIn oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, that are derived from terrestrial environment(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.
