Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

All about Evaporite and Andesite Properties
Know all about Evaporite and Andesite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Andesite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Andesite is Aphanitic to Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Andesite appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Andesite is vitreous. Evaporite is available in green, grey, silver, white colors whereas Andesite is available in bluish - grey, grey, pink, yellow 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 Andesite are commemorative tablets, creating artwork.
