One of the most abundant inorganic substances in nature, it is the major component of sedimentary rocks, occurring in a relatively pure state as calcite, aragonite, marble, limestone, and chalk, as well as in animal shells and bones; calcite (Mineralogy): CaCO₃, a colorless to white trigonal mineral of the calcite group that occurs in highly varied crystal forms; the chief ingredient of all limestones and marble, and one of the most widely distributed minerals in the world; trimorphous with aragonite and vaterite, and forms a series with rhodochrosite) |
