Ol Doinyo Lengai

Ol Doinyo Lengai, Tanzania

The only known carbonatite volcano in the world (except for the neighboring Kerimasi volcano). The volcano produces natrocarbonatite lava with nearly unique minerals – nyerereite and gregoryite. Lava flows at very low temperature at 500 – 600 ° C. Carbonates react with the moisture of the atmosphere and quickly turn white, creating a unique volcanic landscape. Here in a steep cone has been observed formation of a new, nearly unique lava cave with enormous stalactites made of fragile natrocarbonatite.
