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

More about Adakite and Evaporite
Here you can know more about Adakite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Evaporite consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all . When we have to compare Adakite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Adakite is Dull and Soft and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Adakite vs Evaporite. The hardness of Adakite is 3-4 and that of Evaporite is 2-3. The types of Adakite are Not Available whereas types of Evaporite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black while that of Evaporite is white.
