Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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

All about Norite and Evaporite Properties
Know all about Norite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Norite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Norite is Phaneritic whereas that of Evaporite is Earthy. Norite appears Veined and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Norite is not available while that of Evaporite is subvitreous to dull. Norite is available in dark grey to black colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
