Formation
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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 Evaporite and Travertine Properties
Know all about Evaporite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Travertine belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Travertine is Banded. Evaporite appears Glassy, Vesicular and Foilated and Travertine appears Fibrous. The luster of Evaporite is subvitreous to dull while that of Travertine is dull to pearly. Evaporite is available in colourless, green, grey, silver, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
