· Calcite is a carbonate mineral. Carbonates are an important part of the Earth's crust and are found in sedimentary, metamorphic, and igneous rocks. Carbonates are minerals which contain the carbonate group CO 3 as their basic structural unit. They form in a trigonal system with one carbon atom centrally located between 3 oxygen atoms.
