Rhombohedral Group (type of hexagonal symmetry; have rhombohedral cleavage, i.e., pushed over cube) - calcite (CaCO3), dolomite (CaMg(CO3)2, siderite (FeCO3), magnesite (MgCO3), rhodochrosite (MnCO3), and smithsonite (ZnCO3). Orthorhombic - aragonite* (polymorph of calcite - CaCO3); Monoclinic - Azurite (blue) and Malachite (bright green, gem stone); various amounts of Cu2+, CO32-, and OH-, form during hydrothermal alteration in copper ore deposits.
