Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Norite 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 Norite Properties
Know all about Evaporite and Norite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Norite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Norite is Phaneritic. Evaporite appears Glassy, Vesicular and Foilated and Norite appears Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Norite is not available. Evaporite is available in colourless, green, grey, silver, white colors whereas Norite is available in dark grey to black 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 Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
