Formation

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

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Evaporite and Granulite Properties

Know all about Evaporite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Evaporite is Earthy whereas that of Granulite is Granoblastic. Evaporite appears Glassy, Vesicular and Foilated and Granulite appears Veined or Pebbled. The luster of Evaporite is subvitreous to dull while that of Granulite is vitreous. Evaporite is available in green, grey, silver, white colors whereas Granulite is available in black, brown 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
