Formation

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.   
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Quartzite and Granulite Properties

Know all about Quartzite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite and Granulite belong to Metamorphic Rocks.Texture of Quartzite is Foliated, Granular whereas that of Granulite is Granoblastic. Quartzite appears Lustrous and Granulite appears Veined or Pebbled. The luster of Quartzite and Granulite is vitreous. Quartzite and Granulite are available in black, blue, brown, green, light grey, purple, white, yellow 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
