Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Evaporite and Pegmatite Properties
Know all about Evaporite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Pegmatite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Pegmatite is Pegmatitic. Evaporite appears Glassy, Vesicular and Foilated and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Pegmatite is grainy, pearly and vitreous. Evaporite is available in colourless, green, grey, silver, white colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow 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 Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
