Physical properties
Hardness of 3 on the Mohs scale, colors ranging from white to gray and green, vitreous to dull luster, and granular crystal structure.
Formation & geological history
Formed through regional or contact metamorphism of sedimentary carbonate rocks, primarily limestone or dolostone, over millions of years.
Uses & applications
Widely utilized in sculpture, interior architecture, flooring, and monumental construction.
Geological facts
Marble reacts strongly with dilute hydrochloric acid by effervescing due to its calcium carbonate composition.
Field identification & locations
Identified by its softness, characteristic acid reaction, and swirling veining patterns; commonly found in mountainous or tectonic regions worldwide.
