Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Travertine and Pseudotachylite Properties
Know all about Travertine and Pseudotachylite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Pseudotachylite belongs to Metamorphic Rocks.Texture of Travertine is Banded whereas that of Pseudotachylite is Quench. Travertine appears Fibrous and Pseudotachylite appears Dull and Soft. The luster of Travertine is dull to pearly while that of Pseudotachylite is vitreous. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Pseudotachylite is available in black, brown, green, grey, pink, white colors. The commercial uses of Travertine and Pseudotachylite are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
