Calcite

Calcite is a mineral composed of Calcium Carbonate (CaCO3). It exists as two forms, low and high Magnesium (Mg). Only low Mg is stable at the Earth's surface. Calcium Carbonate can also be found as aragonite, which is a polymorph of calcite. Calcite crystals may also show double refraction.

Calcite

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380–470°C, and vaterite is even less stable. ==Properties== Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural...
