Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Travertine and Eclogite Properties
Know all about Travertine and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Travertine is Banded whereas that of Eclogite is Earthy. Travertine appears Fibrous and Eclogite appears Dull, Banded and Foilated. The luster of Travertine is dull to pearly while that of Eclogite is subvitreous to dull. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Eclogite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Travertine and Eclogite are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
