Marble: A Metamorphic Rock with Many Uses
Marble is a metamorphic rock that forms when limestone or dolomite is subjected to heat, pressure and aqueous solutions. It is composed of interlocking crystals of carbonate minerals, usually calcite or dolomite. Marble has a crystalline texture that varies in thickness and can be polished to a high shine. Marble is widely used for sculpture, architecture and decorative purposes.
Its name comes from ancient times, precisely from ancient Greece: the word derives from the verb “marmar“, which means “to shine“.
