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

All about Gritstone and Evaporite Properties
Know all about Gritstone and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone and Evaporite belong to Sedimentary Rocks.Texture of Gritstone is Earthy whereas that of Evaporite is Earthy. Gritstone appears Layered and Foliated and Evaporite appears Glassy, Vesicular and Foilated. The luster of Gritstone is dull while that of Evaporite is subvitreous to dull. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses 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 and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
