Calcite
Dolomite [CaMg(CO 3) 2] with calcite is the most common mineral in carbonate rocks. The mineral dolomite crystallizes in the trigonal–rhombohedral system. It develops white, gray to pink, commonly curved crystals, usually in the massive forms. It has physical properties similar to those of the mineral calcite.
