Marble is metamorphic rock formed by alteration of limestone or dolomite, often irregularly colored by impurities. Granular limestone or dolomite that has recrystallized under the influence of heat, pressure, and aqueous solutions.
Pure marbles attaining 99% calcium carbonate, CaCO3, are often formed by simple recrystallization of sedimentary limestone. Marbles range in color from snow-white to gray and black, many varieties being some shade of red, yellow, pink, green, or buff; the colors, which are caused by the presence of impurities, are frequently arranged in bands or patches and add to the beauty of the stone when it is cut and polished.
