limestone calcite marble
Calcite
Calcite is the primary mineral component of limestone and its metamorphic form, marble. It is very soluble in groundwater and is common in the shells of invertebrates like clams and oysters. A large percentage of the calcite in rocks was deposited in sedimentary environments of both chemical (limestone) and biochemical (chalk) origin.
