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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
