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.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

All about Carbonatite and Marl Properties
Know all about Carbonatite and Marl properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Marl belongs to Sedimentary Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Marl is Earthy. Carbonatite appears Dull, Banded and Foilated and Marl appears Rough and Dull. The luster of Carbonatite is subvitreous to dull while that of Marl is dull. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Marl is available in beige, brown, green, grey, 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 Marl are creating artwork, soil conditioner.
