Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
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 Peridotite and Travertine Properties
Know all about Peridotite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Travertine is Banded. Peridotite appears Rough and Shiny and Travertine appears Fibrous. The luster of Peridotite is shiny while that of Travertine is dull to pearly. Peridotite is available in dark greenish - grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
