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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

All about Travertine and Blueschist Properties
Know all about Travertine and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Travertine is Banded whereas that of Blueschist is Foliated. Travertine appears Fibrous and Blueschist appears Dull and Banded. The luster of Travertine is dull to pearly while that of Blueschist is dull. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
