Physical properties

Hardness of 3 on the Mohs scale with a vitreous to dull luster. Typically displays white, tan, cream, or rusty coloration with banded or fibrous crystal structures.

Formation & geological history

Formed by the precipitation of carbonate minerals from supersaturated hydrothermal waters, often around hot springs or limestone caves.

Uses & applications

Extensively utilized in building construction, interior flooring, wall tiles, and decorative countertops.

Geological facts

Famous structures such as the Roman Colosseum were built largely using travertine. Its porous texture is created by trapped carbon dioxide bubbles during formation.

Field identification & locations

Easily identified by its characteristic fibrous banding and acid effervescence when tested with vinegar. Found globally near geothermal features, prominently in Italy and Turkey.
