Formation

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.

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

All about Granulite and Evaporite Properties

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