Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Charnockite and Evaporite Properties
Know all about Charnockite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Charnockite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Charnockite is Granular whereas that of Evaporite is Earthy. Charnockite appears Veined or Pebbled and Evaporite appears Glassy, Vesicular and Foilated. The luster of Charnockite is not available while that of Evaporite is subvitreous to dull. Charnockite is available in black, grey, orange, pink, white colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Charnockite are curling, gemstone, laboratory bench tops, tombstones and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
