5 Formation

5.1 Formation

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.

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.

All about Epidosite and Carbonatite Properties

Know all about Epidosite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Epidosite and Carbonatite belong to Igneous Rocks.Texture of Epidosite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Carbonatite is Granular, Poikiloblastic. Epidosite appears Dull and Soft and Carbonatite appears Dull, Banded and Foilated. The luster of Epidosite is not available while that of Carbonatite is subvitreous to dull. Epidosite is available in black, brown, light to dark grey colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Epidosite are commemorative tablets, creating artwork and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
