Definition
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Luxullianite and Quartzite Properties
Know all about Luxullianite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Luxullianite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Luxullianite is Granular, Phaneritic whereas that of Quartzite is Foliated, Granular. Luxullianite appears Veined or Pebbled and Quartzite appears Lustrous. The luster of Luxullianite is dull to grainy with sporadic parts pearly and vitreous while that of Quartzite is vitreous. Luxullianite is available in black, grey, orange, pink, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Luxullianite are creating artwork, curling, gemstone, laboratory bench tops, tombstones 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.
