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.

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Carbonatite and Anorthosite Properties

Know all about Carbonatite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Anorthosite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Anorthosite is Foliated, Glassy. Carbonatite appears Dull, Banded and Foilated and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Carbonatite is subvitreous to dull while that of Anorthosite is pearly to subvitreous. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Anorthosite are creating artwork, curling.
