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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

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