Calcite limestone
Calcite also forms flat, rhomboid “poker chip” crystals, but dolomite does not. Calcite responds vigorously to acid, while dolomite responds less vigorously. Calcite is 3 on the Mohs Scale of Hardness, but dolomite is only Mohs 4-4.5. One other difference you may see is the smoothness of the crystal faces on your specimen.calcium carbonate (CaCO3), chemical compound consisting of one atom of calcium, one of carbon, and three of oxygen that is the major constituent of limestone, marble, chalk, eggshells, bivalve shells, and corals. Calcium carbonate is either a white powder or a colorless crystal. When heated, it produces carbon dioxide and calcium oxide (also ...
