5 Formation

5.1 Formation

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

Ijolite 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 Ijolite Properties

Know all about Evaporite and Ijolite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Ijolite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Ijolite is Earthy, Granular. Evaporite appears Glassy, Vesicular and Foilated and Ijolite appears Banded and Foilated. The luster of Evaporite is subvitreous to dull while that of Ijolite is greasy to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Ijolite is available in brown, buff, cream, 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 Ijolite are cemetery markers, creating artwork.
