Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Carbonatite and Limestone Properties
Know all about Carbonatite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Limestone is Clastic or Non-Clastic. Carbonatite appears Dull, Banded and Foilated and Limestone appears Rough and Banded. The luster of Carbonatite is subvitreous to dull while that of Limestone is dull to pearly. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, 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 Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
