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.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

All about Carbonatite and Andesite Properties

Know all about Carbonatite and Andesite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Andesite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Andesite is Aphanitic to Porphyritic. Carbonatite appears Dull, Banded and Foilated and Andesite appears Dull and Soft. The luster of Carbonatite is subvitreous to dull while that of Andesite is vitreous. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Andesite is available in bluish - grey, grey, pink, 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 Andesite are commemorative tablets, creating artwork.
