Boninite and Quartzite
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
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Boninite and Quartzite Properties
Know all about Boninite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Quartzite is Foliated, Granular. Boninite appears Dull and Soft and Quartzite appears Lustrous. The luster of Boninite and Quartzite is vitreous. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow 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 Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
