5 Formation

1.1 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.

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 Carbonatite and Dolomite Properties

Know all about Carbonatite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Dolomite is Earthy. Carbonatite appears Dull, Banded and Foilated and Dolomite appears Glassy or Pearly. The luster of Carbonatite is subvitreous to dull while that of Dolomite is vitreous and pearly. Carbonatite and Dolomite are available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux 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).
