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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Travertine and Arkose Properties
Know all about Travertine and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Travertine and Arkose belong to Sedimentary Rocks.Texture of Travertine is Banded whereas that of Arkose is Clastic. Travertine appears Fibrous and Arkose appears Rough and Dull. The luster of Travertine is dull to pearly while that of Arkose is dull. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Arkose is available in reddish brown colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
