Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

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.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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