Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Basanite and Quartzite Properties
Know all about Basanite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Quartzite is Foliated, Granular. Basanite appears Glassy or Pearly and Quartzite appears Lustrous. The luster of Basanite is waxy and dull while that of Quartzite is vitreous. Basanite is available in black, brown, green, grey, red, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses 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 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.
