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

Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
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 Eclogite and Travertine Properties
Know all about Eclogite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Eclogite belongs to Metamorphic Rocks while Travertine belongs to Sedimentary Rocks.Texture of Eclogite is Earthy whereas that of Travertine is Banded. Eclogite appears Dull, Banded and Foilated and Travertine appears Fibrous. The luster of Eclogite is subvitreous to dull while that of Travertine is dull to pearly. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Eclogite are creating artwork, gemstone and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
