Calcite a carbonate mineral the most stable polymorph of calcium carbonate .The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380-470 C, and vaterite is even less stable. Calcite exhibits several twinning types adding to the variety of observed forms. It may occur as fibrous, granular, lamellar, or compact.

INrnonucrronr Calcite (rhombohedral calcium carbonate) is an envi- ronmentally important mineral. It acts as a buffer in sea water (Winchesuer, 1972), forms the major inorganic part of sea shells, and is secreted by some organisms, such as corals, to form solid skeletal structures (Schmalz, 1972).

It is also the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs. Calcite is often the primary constituent of the shells of marine organisms, e.g., plankton. Calcite represents the stable form of calcium carbonate; aragonite will change to calcite at 470C, and vaterite, or CaCO3, is less stable.
