Marble is a metamorphic recrystallized carbonate mineral, most commonly calcite or dolomite. Marble typically does not foil, although there are exceptions. In geology the term marble refers to metamorphic limestone, but the use of stonemasonry covers limestone at the wider bottom. [1] Marble is often used in sculpture and building material.
Marble is a rock that originates from the metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite rock. Metamorphism causes variable recrystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. The primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been altered or destroyed.
Pure white marble is the result of the metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic eddies and veins of many colored marble varieties are often caused by various mineral impurities, such as clay, silt, sand, iron oxides or chert, initially found as grains or layers in limestone. Green coloration is often caused by serpentine originally originating from dolomite, magnesium-rich limestone or silica impurities. These various impurities were set in motion and recrystallized by the intense pressure and heat of the metamorphism.
