Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

All about Quartzite and Breccia Properties
Know all about Quartzite and Breccia properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Breccia belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Breccia is Brecciated, Clastic. Quartzite appears Lustrous and Breccia appears Layered, Banded, Veined and Shiny. The luster of Quartzite is vitreous while that of Breccia is dull to pearly. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, 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 Breccia are creating artwork, gemstone, jewelry.
