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