WebChalk: composed of the carbonate tests (shells) of foraminifera (small organisms as small as a pin head). Travertine: limestone formed by the evaporation of water. Oolitic limestone: composed of oolites which form as tiny seed particles act as the nucleus for calcite precipitation; need a swashing effect. WebThis natural separation of sediment based on size is known as sorting. Sediment that is well sorted will be composed of material that is all similar in size. Poorly sorted sediment, however, will be composed of sediment of all different sizes. In general well sorted sediments are typically deposited by moving water or wind.
