Physical properties
Hardness of 3 on the Mohs scale, colors ranging from white to tan and cream, vitreous to dull luster, and a microcrystalline structure.
Formation & geological history
Formed by the precipitation of carbonate minerals from supersaturated hydrothermal waters, commonly around hot springs or limestone caves.
Uses & applications
Widely used in architecture for flooring, wall tiles, and paving, as well as in ornamental carvings and collector displays.
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
Easily identified by its fibrous or concentric banded layering and small cavities formed by trapped gas bubbles; found globally in limestone-rich regions.
