Formation

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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

All about Phonolite and Evaporite Properties

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