Foidolites 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.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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