Carbonatite

Carbonatite (pronunciation: /kɑːrˈbɒnətaɪt/) is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50 percent carbonate minerals. Carbonatites may be confused with marble, and may require geochemical verification. Nearly all carbonatite occurrences are intrusives or subvolcanic intrusives. This is because carbonatite lava flows are unstable and react quickly in the atmosphere. Carbonatite lavas may not be as uncommon as thought, but have been poorly preserved throughout earth's history.
