1 Definition

1.1 Definition

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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

5 Formation

5.1 Formation

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

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.

All about Limestone and Carbonatite Properties

Know all about Limestone and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Carbonatite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Carbonatite is Granular, Poikiloblastic. Limestone appears Rough and Banded and Carbonatite appears Dull, Banded and Foilated. The luster of Limestone is dull to pearly while that of Carbonatite is subvitreous to dull. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses 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 and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
