Physical properties
Mohs hardness of 3, varies in color from white to tan and cream, vitreous to dull luster, and possesses a banded or fibrous crystal structure.
Formation & geological history
Formed through the precipitation of carbonate minerals from supersaturated hydrothermal waters, typically around hot springs or limestone caves.
Uses & applications
Widely used as a dimensional stone for architectural building facades, interior flooring, tiles, countertops, and decorative carvings.
Geological facts
Travertine has been used as a building material since ancient times, most famously in the construction of the Colosseum in Rome.
Field identification & locations
Identified by its characteristic fibrous banding and reactive effervescence when exposed to dilute hydrochloric acid; commonly found in Italy, Turkey, and the US.
