Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Laterite and Evaporite Properties
Know all about Laterite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite and Evaporite belong to Sedimentary Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Evaporite is Earthy. Laterite appears Rough and Banded and Evaporite appears Glassy, Vesicular and Foilated. The luster of Laterite is dull while that of Evaporite is subvitreous to dull. Laterite is available in brown, buff, red colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
