Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

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

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