Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

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.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Carbonatite and Pantellerite Properties
Know all about Carbonatite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Pantellerite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Pantellerite is Eutaxitic. Carbonatite appears Dull, Banded and Foilated and Pantellerite appears Layered and Foliated. The luster of Carbonatite is subvitreous to dull while that of Pantellerite is earthy. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Pantellerite is available in dark greenish - 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 Pantellerite are creating artwork.
