1.1 Definition

Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions

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

All about Lamprophyre and Boninite Properties

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