5 Formation

5.1 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.

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Peridotite and Dolomite Properties

Know all about Peridotite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Dolomite is Earthy. Peridotite appears Rough and Shiny and Dolomite appears Glassy or Pearly. The luster of Peridotite is shiny while that of Dolomite is vitreous and pearly. Peridotite is available in dark greenish - grey colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, 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 Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
