2022-7-7 Keywords. Carbonate minerals have a carbonate anion and usually have a divalent cation such as Ca 2+, Mg 2+, Fe 2+, or Mn 2+. For this reason, the formula of carbonate minerals is often written as M 2+ CO 3. (M: divalent cation). Most natural carbonate minerals are formed by the reaction of M 2+ and CO 2 from air dissolved in the ocean.

Rhodochrosite. Rhodochrosite is a carbonate mineral with formula: MnCO3. It has a classic rose-pink color, but specimens can also be brown or gray. It forms dogtooth or rhombohedral crystals like calcite, but it may also occur in stalactitic, granular, nodular, botryoidal, and massive habits. Rhodochrosite is found in hydrothermal ore veins
