Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides

Archaeological Significance
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.
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Carbonatite and Mugearite Properties
Know all about Carbonatite and Mugearite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Mugearite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Carbonatite appears Dull, Banded and Foilated and Mugearite appears Dull and Soft. The luster of Carbonatite is subvitreous to dull while that of Mugearite is . Carbonatite is available in black, brown, green, grey, pink, white colors whereas Mugearite is available in black, brown, light to dark grey colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Mugearite are creating artwork.
