Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

All about Evaporite and Gabbro Properties
Know all about Evaporite and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Gabbro belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Gabbro is Phaneritic. Evaporite appears Glassy, Vesicular and Foilated and Gabbro appears Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Gabbro is . Evaporite is available in green, grey, silver, white colors whereas Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
