Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

All about Evaporite and Gritstone Properties
Know all about Evaporite and Gritstone properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Gritstone belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Gritstone is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Gritstone appears Layered and Foliated. The luster of Evaporite is subvitreous to dull while that of Gritstone is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, 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 Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones.
