Formation

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

Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Evaporite and Carbonatite Properties

Know all about Evaporite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Carbonatite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Carbonatite is Granular, Poikiloblastic. Evaporite appears Glassy, Vesicular and Foilated and Carbonatite appears Dull, Banded and Foilated. The luster of Evaporite and Carbonatite is subvitreous to dull. Evaporite is available in green, grey, silver, white colors whereas Carbonatite is available in black, brown, green, grey, pink, white 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 Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
