Physical properties
Hardness of 3 on the Mohs scale, colors range from white to cream, tan, and rusty varieties, sub-crystalline to earthy luster, porous and fibrous crystal structure, specific gravity around 2.5 - 2.8
Formation & geological history
Formed by the precipitation of carbonate minerals from mineral-saturated waters, especially around hot springs, caves, and rivers
Uses & applications
Commonly used in architecture for flooring, wall cladding, and patios, as well as decorative items and interior design
Geological facts
Travertine has been used as a building material since ancient times, most notably in the construction of the Colosseum in Rome
Field identification & locations
Identified by its characteristically fibrous or concentric banding and prominent porous texture, frequently found near geothermal springs and limestone caves globally
