Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Diorite and Evaporite Properties
Know all about Diorite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Diorite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Diorite is Phaneritic whereas that of Evaporite is Earthy. Diorite appears Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Diorite is shiny while that of Evaporite is subvitreous to dull. Diorite is available in black, brown, light to dark grey, white colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Diorite are creating artwork, curling and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
