Formation

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

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 Diatomite and Peridotite Properties

Know all about Diatomite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite belongs to Sedimentary Rocks while Peridotite belongs to Igneous Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Peridotite is Phaneritic. Diatomite appears Soft and Peridotite appears Rough and Shiny. The luster of Diatomite is dull while that of Peridotite is shiny. Diatomite is available in grey, white, yellow colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
