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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Peridotite and Carbonatite Properties
Know all about Peridotite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite and Carbonatite belong to Igneous Rocks.Texture of Peridotite is Phaneritic whereas that of Carbonatite is Granular, Poikiloblastic. Peridotite appears Rough and Shiny and Carbonatite appears Dull, Banded and Foilated. The luster of Peridotite is shiny while that of Carbonatite is subvitreous to dull. Peridotite is available in dark greenish - grey colors whereas Carbonatite 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 Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
