Formation

Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Granodiorite and Quartzite Properties

Know all about Granodiorite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Quartzite is Foliated, Granular. Granodiorite appears Veined or Pebbled and Quartzite appears Lustrous. The luster of Granodiorite is grainy, pearly and vitreous while that of Quartzite is vitreous. Granodiorite 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 Granodiorite are 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.
