Definition

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

Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation

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

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Quartzite and Basanite Properties

Know all about Quartzite and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Basanite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Basanite is Aphanitic to Porphyritic. Quartzite appears Lustrous and Basanite appears Glassy or Pearly. The luster of Quartzite is vitreous while that of Basanite is waxy and dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Basanite is available in black, brown, green, grey, red, white 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 Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
