Muambe Carbonatite Plug


Circular carbonatite plug which with its aureole of feldspathic rocks is 5 km in diameter. The feldspathic rocks form a circular ridge, rising to some 400 m above the surrounding plain, that envelopes an inner crater-like depression within which are craggy hills of carbonatite.

There is an extensive fluorite mineralization in the contact zone between carbonatite and fenite. In some trenches masses of fluorite up to 20 cm thick were encountered. Blue and yellow varieties, the former being rich in Be (concentration as high as 10000ppm), Sr, Y and La (Cilek 1989).
