5 Formation

5.1 Formation

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

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

All about Quartzite and Dolomite Properties

Know all about Quartzite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Dolomite is Earthy. Quartzite appears Lustrous and Dolomite appears Glassy or Pearly. The luster of Quartzite is vitreous while that of Dolomite is vitreous and pearly. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Dolomite is available in black, brown, colourless, 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 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).
