Formation

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

Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

All about Evaporite and Granite Properties

Know all about Evaporite and Granite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Granite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Granite is Granular, Phaneritic. Evaporite appears Glassy, Vesicular and Foilated and Granite appears Veined or Pebbled. The luster of Evaporite is subvitreous to dull while that of Granite is dull to grainy with sporadic parts pearly and vitreous. Evaporite is available in green, grey, silver, white colors whereas Granite is available in black, grey, orange, pink, 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 Granite are curling, gemstone, laboratory bench tops, tombstones, used in aquariums.
