Physical properties
Mohs hardness of 3 to 4, varies in color from white to pink and dark gray with veining, exhibits a vitreous to greasy luster, and has a granular crystalline structure.
Formation & geological history
Formed through the regional or contact metamorphism of sedimentary carbonate rocks, typically limestone or dolostone, under immense heat and pressure.
Uses & applications
Widely utilized in architecture, sculpture, interior design, and decorative tiles due to its aesthetic appeal and polishability.
Geological facts
Marble reacts vigorously with dilute hydrochloric acid, releasing carbon dioxide gas, and has been favored by sculptors since antiquity for its fine grain.
Field identification & locations
Identified by its softness, distinct veining patterns, and acid reactivity; commonly quarried in Italy, Greece, the US, and China.
