1 Definition

1.1 Definition

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

5 Formation

5.1 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.

Felsite 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 Felsite Properties

Know all about Carbonatite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Felsite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Felsite is Arborescent Patterned, Vitreous. Carbonatite appears Dull, Banded and Foilated and Felsite appears Layered, Banded, Veined and Shiny. The luster of Carbonatite is subvitreous to dull while that of Felsite is vitreous. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, 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 Felsite are mirror, jewelry.
