Ol Doinyo Lengai is a volcano located in Tanzania and is part of the volcanic system of the Great Rift Valley in eastern Africa. Ol Doinyo Lengai is unique among volcanoes in that it produces natro-carbonititic lava, an unusual type of carbonatite. Image File history File linksMetadata Oldoinyolengai. ...

Carbonatites are intrusive igneous rock structures with more than 50% carbonate content, many of which contain distinctive abundances of apatite, magnetite, barite, and fluorite, that may contain economic or anomalous concentrations of rare earth elements, phosphorus, niobium, uranium, thorium, copper, iron, titanium, barium, fluorine, zirconium, and other rare or incompatible...
Whereas most lavas are rich in silicate minerals, the lava of Ol Doinya Lengai is rich in the rare sodium and potassium carbonates, nyerereite and gregoryite. Due to this unusual composition, the lava is erupted at relatively low temperatures (approximately 500-600 degrees Celsius). This temperature is so low that the molten lava appears black in sunlight, rather than having the red glow common to most lavas. It is also much more fluid than silicate lavas. The sodium and potassium carbonate minerals of the lavas formed by Ol Doinyo Lengai are unstable at the Earth's surface and susceptible to rapid weathering, quickly turning from black to grey in color. The resulting volcanic landscape is different from any other in the world. The chemical makeup of the lava has been compared to dish soap.

Ol Doinyo Lengai's lava only looks red in pictures after a long exposure. Its lava deteriorates very quickly standing 3-4 days before disintigrating. Its lava comes out at aproximately 1000 degrees fahrenheit, it can be collected with a spoon. It is the only active volcano in the world that erupts at that temperature currently.
The most recent eruption took place on the 27th of March 2006.
