All about Sovite and Dunite Properties
Know all about Sovite and Dunite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Dunite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Dunite is Phaneritic. Sovite appears Dull, Banded and Foilated and Dunite appears Rough and Shiny. The luster of Sovite is subvitreous to dull while that of Dunite is shiny. Sovite is available in black, brown, colourless, green, grey, pink, white colors whereas Dunite is available in dark greenish - grey colors. The commercial uses of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Dunite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
