Dolomite is a naturally occurring double carbonate consisting of a structural arrangement of calcium carbonate CaCO3 and magnesium carbonate MgCO3. The nodular particle shape of dolomite crystals has similarities to marble ones. Therefore, dolomite is often present together with marble. Its sedimentary origin had been subjected to high pressure and temperature (metamorphosis) during movements in the earth's crust. High-purity, selected dolomite rocks provide very bright, neutral white color tones for various markets.
