Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
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 Oil shale and Travertine Properties
Know all about Oil shale and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale and Travertine belong to Sedimentary Rocks.Texture of Oil shale is Splintery whereas that of Travertine is Banded. Oil shale appears Muddy and Travertine appears Fibrous. The luster of Oil shale is dull while that of Travertine is dull to pearly. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Oil shale are an oil and gas reservoir and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
