Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

All about Travertine and Adakite Properties
Know all about Travertine and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Adakite belongs to Igneous Rocks.Texture of Travertine is Banded whereas that of Adakite is Porphyritic. Travertine appears Fibrous and Adakite appears Dull and Soft. The luster of Travertine is dull to pearly while that of Adakite is grainy, pearly and vitreous. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Adakite is available in black, brown, light to dark grey colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Adakite are commemorative tablets, pottery, used in aquariums.
