Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Archaeological Significance
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Quartzite and Carbonatite Properties
Know all about Quartzite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Carbonatite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Carbonatite is Granular, Poikiloblastic. Quartzite appears Lustrous and Carbonatite appears Dull, Banded and Foilated. The luster of Quartzite is vitreous while that of Carbonatite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Carbonatite is available in black, brown, green, grey, 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 Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
