Calcite

The most widely known biomineral is calcite that forms the 'hard part' of many common invertebrates, such as corals and mollusks. Anhydrous calcium carbonate, CaCO 3, is but one of the eight mineral end-members with identical crystal structure but different divalent cations that form the calcite group (Gaines et al., 1997, p. 427).These minerals, many almost as common …
