This poses a serious challenge to the understanding of the depositional system and the properties of facies distribution.For sediment to become sedimentary rock, it usually undergoes burial, compaction, and cementation. Clastic sedimentary rocks are the result of weathering and erosion of source rocks, which turns them into pieces—clasts—of rocks and minerals.

Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.Chert is widespread, but not widely known by the public as a distinct rock type. Chert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture.Many types of chert fit into this categorization.What type of sedimentary rock is chalk clastic chemical or organic? None of the above. Marble is a metamorphic rock.
