Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

Archaeological Significance
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

All about Quartzite and Wackestone Properties
Know all about Quartzite and Wackestone properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Wackestone belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Wackestone is Clastic. Quartzite appears Lustrous and Wackestone appears Rough and Dull. The luster of Quartzite is vitreous while that of Wackestone is dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Wackestone is available in black, blue, brown, green, grey, orange, red, 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 Wackestone are cemetery markers, pottery.
