The native Maasai people regard this mountain as the "Mountain of God" which is what Ol Doinyo Lengai translates to in the Maa language. Ol Doinyo Lengai is a stratovolcano that is part of the Great Rift Valley located in Eastern Africa where the Nubian Plate and the Somali Plate are diverging (moving away) from each other. The geology of this system is pretty spectacular but I am focussing on Ol Doinyo Lengai because it is currently the only known ACTIVE natrocarbonatite volcano in the world.

Industrially important minerals associated with some carbonatites are apatite, barite and vermiculite.
