Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental 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 Granodiorite and Travertine Properties
Know all about Granodiorite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Travertine is Banded. Granodiorite appears Veined or Pebbled and Travertine appears Fibrous. The luster of Granodiorite is grainy, pearly and vitreous while that of Travertine is dull to pearly. Granodiorite is available in black, grey, orange, pink, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Granodiorite are curling, gemstone, laboratory bench tops, tombstones and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
