Formation

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

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

All about Evaporite and Tonalite Properties

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