Boninite and Sovite
Definition
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
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Sovites are formed due to low degrees of partial melting of rocks.

All about Boninite and Sovite Properties
Know all about Boninite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Sovite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Sovite is Granular, Poikiloblastic. Boninite appears Dull and Soft and Sovite appears Dull, Banded and Foilated. The luster of Boninite is vitreous while that of Sovite is subvitreous to dull. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Sovite is available in black, brown, colourless, green, grey, pink, 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 Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
