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

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

All about Quartzite and Boninite Properties
Know all about Quartzite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Boninite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Boninite is Aphanitic to Porphyritic. Quartzite appears Lustrous and Boninite appears Dull and Soft. The luster of Quartzite and Boninite is vitreous. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses 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 and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
