Physical properties
Hardness of 3 on the Mohs scale, white or grey color, vitreous to sugary luster, and massive or granular crystal structure with no cleavage.
Formation & geological history
Formed through the regional or contact metamorphism of sedimentary carbonate rocks, predominantly limestone or dolostone, under extreme heat and pressure.
Uses & applications
Widely used in sculpture, architecture, flooring, and monumental construction due to its aesthetic appeal and workability.
Geological facts
Marble reacts vigorously with hydrochloric acid due to its calcium carbonate composition and has been used by master sculptors like Michelangelo for centuries.
Field identification & locations
Identified by its relatively soft nature, granular texture, and fizzing reaction with acid; commonly found in mountain belts and quarry regions worldwide.
