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

All about Gabbro and Evaporite Properties
Know all about Gabbro and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Gabbro belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Gabbro is Phaneritic whereas that of Evaporite is Earthy. Gabbro appears Veined and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Gabbro is not available while that of Evaporite is subvitreous to dull. Gabbro is available in dark grey to black colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
