Calcite

Calcite is a carbonate mineral and one of the most stable polymorphs of calcium carbonate. It occurs in a variety of environments and is characterized by its numerous crystal forms. It is commonly found in sedimentary rocks, especially limestone, and has numerous industrial applications due to its abundance and diverse properties.
