Formation

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.   
Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Evaporite and Epidosite Properties

Know all about Evaporite and Epidosite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Epidosite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Epidosite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Evaporite appears Glassy, Vesicular and Foilated and Epidosite appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Epidosite is not available. Evaporite is available in colourless, green, grey, silver, white colors whereas Epidosite is available in black, brown, light to dark grey 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 Epidosite are commemorative tablets, creating artwork.
