The active volcano Oldoinyo Lengai, located in the Gregory Rift (part of the East African Rift Valley) produces carbonatite lava whereas most volcanos produce silicate type of lavas. Carbonatite lava erupts at a much lower temperature (around 510°C) and appears black in sunlight, is more fluid than silicate lavas and quickly turns from black to greyish, white. As a result the volcanic landscape is different from any other in the world.
