Physical properties
Hardness of 3 on the Mohs scale, typically white, tan, or cream colored with a vitreous to dull luster and fibrous or concentric crystal structure.
Formation & geological history
Formed by the precipitation of carbonate minerals from supersaturated hydrothermal waters, commonly around hot springs or in limestone caves.
Uses & applications
Widely used in construction for flooring, paving tiles, and interior wall cladding, as well as for decorative landscaping.
Geological facts
Famous for forming the stunning terraced pools at Pamukkale in Turkey and used extensively in ancient Roman architecture including the Colosseum.
Field identification & locations
Identified by its banded appearance, fibrous texture, and strong effervescence when tested with dilute hydrochloric acid; found globally near geothermal features.
