1.1 Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

5 Formation

5.1 Formation

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

Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

All about Evaporite and Adakite Properties

Know all about Evaporite and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Adakite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Adakite is Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Adakite appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Adakite is grainy, pearly and vitreous. Evaporite is available in colourless, green, grey, silver, white colors whereas Adakite is available in black, brown, light to dark grey 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 Adakite are commemorative tablets, pottery, used in aquariums.
