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
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Boninite and Whiteschist Properties
Know all about Boninite and Whiteschist properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Whiteschist belongs to Metamorphic Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Whiteschist is Foliated. Boninite appears Dull and Soft and Whiteschist appears Banded and Foilated. The luster of Boninite is vitreous while that of Whiteschist is subvitreous to dull. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Whiteschist is available in colourless, green, grey, 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 Whiteschist are creating artwork, gemstone, jewelry, production of lime.
