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.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

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