Formation
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

All about Evaporite and Marl Properties
Know all about Evaporite and Marl properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Marl belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Marl is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Marl appears Rough and Dull. The luster of Evaporite is subvitreous to dull while that of Marl is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Marl is available in beige, brown, green, grey, white 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 Marl are creating artwork, soil conditioner.
