The carbonates are a group of minerals that contain the anion group CO32-, and are subdivided into the calcite, aragonite, dolomite or hydrated carbonate subgroups. Rhodochrosite belongs to the calcite subgroup. These carbonates are known for having rhombohedral symmetry, which results in the formation of rare rhombohedron shaped crystals.
