Physical properties
Hardness of 3 on Mohs scale, typically white, tan, or cream colored with a fibrous or concentric texture and vitreous to dull luster.
Formation & geological history
Formed by the precipitation of carbonate minerals from supersaturated groundwaters, especially around hot springs or limestone caves.
Uses & applications
Widely used in architecture for building facades, wall cladding, flooring, and interior design tiles.
Geological facts
Famous ancient structures, including the Colosseum in Rome, were built primarily using travertine.
Field identification & locations
Identified by its characteristic porous, pitted surface texture and effervescence when tested with dilute hydrochloric acid.
