5 Formation

5.1 Formation

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

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Evaporite and Pumice Properties

Know all about Evaporite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Pumice belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Pumice is Vesicular. Evaporite appears Glassy, Vesicular and Foilated and Pumice appears Vesicular. The luster of Evaporite is subvitreous to dull while that of Pumice is earthy. Evaporite is available in colourless, green, grey, silver, white colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey 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 Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums.
