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.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Diatomite and Evaporite Properties

Know all about Diatomite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Diatomite and Evaporite belong to Sedimentary Rocks.Texture of Diatomite is Clastic or Non-Clastic whereas that of Evaporite is Earthy. Diatomite appears Soft and Evaporite appears Glassy, Vesicular and Foilated. The luster of Diatomite is dull while that of Evaporite is subvitreous to dull. Diatomite is available in grey, white, yellow colors whereas Evaporite is available in green, grey, silver, white 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 Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
