Travertine Rock


Travertine rock is a chemical sedimentary rock.

It is a terrestrial counterpart of tufa.





It forms when calcium carbonate precipitates from hot springs and ground and surface water solutions.

It has a concentric or fibrous habit.

It is naturally white, but often strained brownish, reddish or yellow by impurities such as iron oxides and others.

Small organisms such as cyanobacteria, algae and others often live on its surface, which causes the porosity.

Like tufa, it also has a siliceous version called siliceous slinter.

It has been widely used as building material, both in buildings and facades, and inside the buildings such as in tiles and floor installations.
