Formation
Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Lherzolite and Travertine Properties
Know all about Lherzolite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Travertine is Banded. Lherzolite appears Glassy, Vesicular and Foilated and Travertine appears Fibrous. The luster of Lherzolite is subvitreous to dull while that of Travertine is dull to pearly. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
