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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Travertine and Anorthosite Properties
Know all about Travertine and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Travertine is Banded whereas that of Anorthosite is Foliated, Glassy. Travertine appears Fibrous and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Travertine is dull to pearly while that of Anorthosite is pearly to subvitreous. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Anorthosite are creating artwork, curling.
