Definition

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation

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.

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

All about Carbonatite and Quartzite Properties

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