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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Peridotite and Limestone Properties

Know all about Peridotite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Limestone is Clastic or Non-Clastic. Peridotite appears Rough and Shiny and Limestone appears Rough and Banded. The luster of Peridotite is shiny while that of Limestone is dull to pearly. Peridotite is available in dark greenish - grey colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
