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.
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.

All about Travertine and Oil shale Properties
Know all about Travertine and Oil shale properties here. All properties of rocks are important as they define the type of rock and its application. Travertine and Oil shale belong to Sedimentary Rocks.Texture of Travertine is Banded whereas that of Oil shale is Splintery. Travertine appears Fibrous and Oil shale appears Muddy. The luster of Travertine is dull to pearly while that of Oil shale is dull. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Oil shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Oil shale are an oil and gas reservoir.
