Calcite mineral Britannica

Calcite is the stable form of CaCO 3 at most temperatures and pressures. The orthorhombic polymorph of CaCO 3 , aragonite, though frequently deposited in nature, is metastable at room temperature and pressure and readily inverts to calcite; the inversion has been shown experimentally to be spontaneous when aragonite is heated to 400 °C in dry air and at lower temperatures when it is in contact with water.
