5 Formation

5.1 Formation

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

Tuff vs Travertine Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Tuff and Travertine Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Tuff vs Travertine information and Tuff vs Travertine characteristics in the upcoming sections.
