Overall, 527 carbonatite localities are known on Earth, and they are found on all continents and also on oceanic islands. Most of the carbonatites are shallow intrusive bodies of calcite-rich igneous rocks in form of volcanic necks, dykes, and cone-sheets. These generally occur in association with

Geochemically, carbonatites are dominated by incompatible elements (Ba, Cs, Rb) and depletions in compatible elements (Hf, Zr, Ti). This together with their silica-undersaturated composition supports inferences that carbonatites are formed by low degrees of

Trace elements are extremely enriched in carbonatites, and they have the highest concentration of lanthanides of any known rock type. The largest REE-carbonatite deposits are Bayan Obo, Mountain Pass, Maoniuping, and Mount Weld.
