Calcite - Wikipedia Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3) It is a very common mineral, particularly as a component of limestone Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on scratch hardness comparison
Calcite Mineral | Uses and Properties - Geology. com Calcite is the principal constituent of limestone and marble These rocks are extremely common and make up a significant portion of Earth's crust They serve as one of the largest carbon repositories on our planet The properties of calcite make it one of the most widely used minerals
Calcite: Mineral information, data and localities. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties
