	C	13.03		CO2	47.74				This is a reflected light micrograph of polished, carbon coated dolomite crystals. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. This is the best standard for Mg and Ca in mixed carbonate minerals. Dolomite has three good rhombohedral cleavages which results in polished surfaces often having a pitted appearance where the cleavages come together in a re-entrant. Locality unknown
