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

Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle

Formation

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

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

All about Boninite and Peridotite Properties

Know all about Boninite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Peridotite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Peridotite is Phaneritic. Boninite appears Dull and Soft and Peridotite appears Rough and Shiny. The luster of Boninite is vitreous while that of Peridotite is shiny. Boninite is available in bluish - grey, brown, green, grey colors whereas Peridotite is available in dark greenish - grey 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 Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
