Evaporite and Boninite
Definition
Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Evaporite and Boninite Properties
Know all about Evaporite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Boninite is Aphanitic to Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Boninite appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Boninite is vitreous. Evaporite is available in colourless, green, grey, silver, white colors whereas Boninite is available in bluish - grey, brown, colourless, 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
