Calcite is a chemical or biochemical calcium carbonate corresponding to the formula CaCO3 and is one of the most widely distributed minerals on the Earth's surface. It is a common constituent of sedimentary rocks, limestone in particular. It is also the primary mineral in metamorphic
marble. It also occurs as a vein mineral in deposits from hot springs,
and also occurs in caverns as stalactites and stalagmites.Calcite crystals
are hexagonal-rhombohedral, though actual calcite rhombohedrons are rare as natural crystals. However, they show a remarkable variety of habit including acute to obtuse rhombohedrons, tabular forms, prisms, or various scalenohedrons. It may occur as fibrous, granular, lamellar, or compact.
