All about Lamprophyre and Dunite Properties

Know all about Lamprophyre and Dunite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Dunite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Dunite is Phaneritic. Lamprophyre appears Dull, Banded and Foilated and Dunite appears Rough and Shiny. The luster of Lamprophyre is subvitreous to dull while that of Dunite is shiny. Lamprophyre and Dunite are available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Lamprophyre are an oil and gas reservoir, as a feed additive for livestock, 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.
