Definition
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
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 Vogesite and Travertine Properties
Know all about Vogesite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Vogesite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Vogesite is Porphyritic whereas that of Travertine is Banded. Vogesite appears Dull, Banded and Foilated and Travertine appears Fibrous. The luster of Vogesite is subvitreous to dull while that of Travertine is dull to pearly. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Vogesite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
