Dolomite Occurrence, Properties, and Distribution. Dolomite is a carbonate mineral, consisting of calcium magnesium carbonate. It was first described as the 'stinking stone' by Belsazar Hacquet, an Austrian naturalist. Later, Déodat Gratet de Dolomieu, a French naturalist and geologist, described it as a rock from the Dolomite Alps in Italy.
Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate—CaMg(CO3)2. The mineral dolomite crystallizes in the trigonalrhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions.
