1 Definition
1.1 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
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

5 Formation
5.1 Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Boninite and Norite Properties

Know all about Boninite and Norite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Norite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Norite is Phaneritic. Boninite appears Dull and Soft and Norite appears Veined and Shiny. The luster of Boninite is vitreous while that of Norite is not available. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Norite is available in dark grey to black 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 Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
