Definition

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

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Formation

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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

All about Boninite and Evaporite Properties

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