5.1 Formation

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Dunite and Evaporite Properties

Know all about Dunite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Dunite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Dunite is Phaneritic whereas that of Evaporite is Earthy. Dunite appears Rough and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Dunite is shiny while that of Evaporite is subvitreous to dull. Dunite is available in dark greenish - grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Dunite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
