  • Calcite Group: Mineral information, data and localities.

    Calcite group structures are taken by nitrates and carbonates of relatively small cations, including Li, Na, Mg, Ca, Fe 2+, Zn, Co 2+, and Cd. The structure of calcite and its related species is ionic and resembles that of NaCl, the place of the spherical Cl ions being taken by planar (CO 3) 2-or (NO 3) 1-groups. These groups are arranged in parallel position in the crystal with their

  • Calcite Wikipedia

    2020-06-04· Etymology. Calcite is derived from the German Calcit, a term coined in the 19th century from the Latin word for lime, calx (genitive calcis) with the suffix -ite used to name minerals. It is thus etymologically related to chalk.. When applied by archaeologists and stone trade professionals, the term alabaster is used not just as in geology and mineralogy, where it is reserved for a variety of
