Calcium Carbonate Facts Aragonite, Calcite, Travertine

Calcium carbonate (CaCO 3) is a chemical compound of calcium. It is the main component of the shells of marine organisms such as oysters, snails shells, pearls, coral and eggshell. Calcium carbonate occurs as minerals aragonite and calcite. These carbonate minerals form the rock types of limestone, chalk, marble, travertine, tufa and coquina.
