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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

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