Formation
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.
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.

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