Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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 Quartzite and Travertine Properties
Know all about Quartzite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Travertine belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Travertine is Banded. Quartzite appears Lustrous and Travertine appears Fibrous. The luster of Quartzite is vitreous while that of Travertine is dull to pearly. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
