Marble is a non-foliated metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Geologists use the term “marble” to refer to metamorphosed limestone; Marble is commonly used for sculpture and as a building material.
Calcite is a carbonate mineral and the most stable of polymorph of Calcium Carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite (CaCO3) at 380-470 degrees Celcius and vaterite is even less stable.
Calcite (CaCO3) has a defining Mohs hardness of 3, specific gravity of 2.71 and its luster is vitreous in cyrstallized varieties. Color is white or none, though shades of gray, red, orange, yellow, green, blue, violet, brown or even black can occur when the mineral is charged with impurities.
