Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

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.
Epidosite 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 Epidosite Properties
Know all about Carbonatite and Epidosite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Epidosite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Epidosite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Carbonatite appears Dull, Banded and Foilated and Epidosite appears Dull and Soft. The luster of Carbonatite is subvitreous to dull while that of Epidosite is not available. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Epidosite 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 Epidosite are commemorative tablets, creating artwork.
