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 …

Calcite

Calcite is the most common polymorph of calcium carbonate found in the Earth's crust, and it is the main component of limestone. It plays a crucial role in geochemical systems by exchanging carbonate ions with aqueous solutions, influencing the chemical behavior of soils and sediments, and acting as a sink for heavy metals and contaminants in various environments.
