Formation

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

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

All about Peridotite and Evaporite Properties

Know all about Peridotite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Evaporite is Earthy. Peridotite appears Rough and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Peridotite is shiny while that of Evaporite is subvitreous to dull. Peridotite is available in dark greenish - grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Peridotite 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.
