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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

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