Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
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.

All about Itacolumite and Peridotite Properties
Know all about Itacolumite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Itacolumite belongs to Sedimentary Rocks while Peridotite belongs to Igneous Rocks.Texture of Itacolumite is Clastic, Granular, Rough whereas that of Peridotite is Phaneritic. Itacolumite appears Rough and Peridotite appears Rough and Shiny. The luster of Itacolumite is dull while that of Peridotite is shiny. Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Itacolumite are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
