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