Chocolate Marble
Most marbles have been metamorphosed by heat, pressure, or other influences and are composed of at least 90 percent calcite or dolomite, though the term is often applied commercially to any chiefly carbonate rock that acquires a nice luster when polished. A broad range of accessory minerals may be present in marbles, creating an extensive range of marble types that are differentiated by color and pattern.
