1.1 Definition

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

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

5 Formation

5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

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

All about Dolomite and Quartzite Properties

Know all about Dolomite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Dolomite is Earthy whereas that of Quartzite is Foliated, Granular. Dolomite appears Glassy or Pearly and Quartzite appears Lustrous. The luster of Dolomite is vitreous and pearly while that of Quartzite is vitreous. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) 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.
