Granophyre and Quartzite


Definition

Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone   
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass

Formation

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.   
Granophyre is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Quartzite and Granophyre Properties

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