  • Calcite: The mineral Calcite spar information and pictures

    Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in

  • Calcite Wikipedia

    Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even
