Formation & geological history

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

Uses & applications

Widely used in architecture for flooring, wall cladding, and paving due to its durability and aesthetic appeal.

Geological facts

Famous structures like the Roman Colosseum were built largely using travertine. It features characteristic pitted holes and troughs formed by trapped gas bubbles.

Field identification & locations

Identified by its fibrous layered texture, porosity, and effervescence when exposed to hydrochloric acid. Commonly found in Italy, Turkey, and the United States.
