Monte Muambe and the Zambezi River, Mozambique
The ring-shaped caldera of the Monte Muambe in Mozambique can be seen north of the Zambezi River.
Monte Muambe is a dormant volcano located east of Moatize in Mozambique’s Tete Province.
The volcano is 780 meters high and has a 6 kilometer external diameter with a caldera some 200 meters deep.
The caldera is largely composed of carbonatites, rich in both blue and yellow fluorite.
The Zambezi Valley Spatial Development Initiative estimates Monte Muambe has reserves of 1.1 million tonnes of the mineral in a pure form.
The Zambezi River (also spelled Zambesi) is the fourth-longest river in Africa, and the largest flowing into the Indian Ocean from Africa.
The area of its basin is 1,390,000 km² (537,000 miles²), slightly less than half that of the Nile.
The 2,574 km- (1,600 mile-) long river has its source in Zambia and flows through Angola, along the borders of Namibia, Botswana, Zambia, and Zimbabwe, to Mozambique, where it empties into the Indian Ocean.
The white area on the banks of the river to the far left is the city of Tete, the capital of Tete Province and the largest city on the Zambezi.
