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

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