Physical properties

Hardness of 3 on the Mohs scale, typically tan, cream, white, or light brown in color, vitreous to dull luster, fibrous or concentric crystal structure, specific gravity around 2.5 - 2.8

Formation & geological history

Formed by the precipitation of carbonate minerals from hydrothermal springs, particularly hot springs, over thousands of years.

Uses & applications

Widely used as building material for flooring, wall tiles, paving, and architectural facades.

Geological facts

Travertine is a terrestrial sedimentary rock, and the name originates from the Italian town of Tivoli, formerly known as Tibur.

Field identification & locations

Identified by its characteristic fibrous or concentric banded appearance and pitted cavities caused by trapped gas bubbles during formation.
