From the Wikipedia article
Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see dolomite (rock)). An alternative name sometimes used for the dolomitic rock type is dolostone.
