All about Dunite and Rhomb Porphyry Properties

Know all about Dunite and Rhomb Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Dunite and Rhomb Porphyry belong to Igneous Rocks.Texture of Dunite is Phaneritic whereas that of Rhomb Porphyry is Aphanitic to Porphyritic. Dunite appears Rough and Shiny and Rhomb Porphyry appears Rough. The luster of Dunite is shiny while that of Rhomb Porphyry is subvitreous to dull. Dunite is available in dark greenish - grey colors whereas Rhomb Porphyry is available in black, brown, green, grey, pink, 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 Rhomb Porphyry are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
