Physical properties
Mohs hardness of 3, white to tan color with distinct banding, vitreous to dull luster, and effervesces strongly in dilute hydrochloric acid.
Formation & geological history
Formed through the precipitation of carbonate minerals from supersaturated hydrothermal or surface waters, typically around hot springs or limestone caves.
Uses & applications
Widely used in construction for flooring, wall tiles, and architectural facades, as well as for decorative carvings.
Geological facts
Travertine has been used as a building material since ancient Roman times, most famously in the construction of the Colosseum.
Field identification & locations
Easily identified by its characteristic layered banding and porous texture; commonly found in Italy, Turkey, and the western United States.
