Physical properties
Hardness of 3 on the Mohs scale, typically white, gray, or variegated with distinct veining. It exhibits a greasy to sub-vitreous luster and a granular, crystalline texture.
Formation & geological history
Formed through the regional or contact metamorphism of sedimentary carbonate rocks, primarily limestone or dolostone, under immense heat and pressure over millions of years.
Uses & applications
Widely used in sculpture, architecture, monuments, floor tiles, and interior decorative surfaces due to its aesthetic appeal and polishability.
Geological facts
Famous historical structures like the Taj Mahal and Michelangelo's David are sculpted from pure white marble. It reacts vigorously with dilute hydrochloric acid due to its calcium carbonate composition.
Field identification & locations
Easily identified by its characteristic veining, softness compared to granite, and effervescence with acid. Found globally in regions with ancient tectonic activity such as Italy, Greece, and the United States.
