Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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