5 Formation
5.1 Formation
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form 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 Comendite and Evaporite Properties

Know all about Comendite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Comendite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Comendite is Porphyritic whereas that of Evaporite is Earthy. Comendite appears Foliated and Evaporite appears Glassy, Vesicular and Foilated. The luster of Comendite is dull while that of Evaporite is subvitreous to dull. Comendite is available in blue, bluish - grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Comendite are cemetery markers and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
