Mineral Specimens from Congo - Classic Specimen Localities

Confusingly, there are two countries in Africa with Congo in their name – the Democratic Republic of the Congo (DRM, Congo-Kinshasa) and the Republic of the Congo (RC, Congo-Brazzaville). Both these neighbouring countries reflect some of Africa’s most contrasting geology: the ancient Congo Craton and its vast Congo Basin cover, the Neoproterozoic Katanga Basin folded into the Lufilian Arc, and the geologically young East African Rift in the east. The DRM is particularly famous for its Central African Copperbelt, which hosts world-class sediment-hosted copper–cobalt deposits, famed in collections for vivid secondary Cu minerals such as malachite, azurite, chrysocolla and cuprite. Farther north the Kibaran Belt’s granites and pegmatites are important for rare metal elements, including Sn–Ta–Nb (coltan). The RC, while smaller, is no less interesting mineralogically with its rich secondary copper minerals that include diopside and aurichalcite, as well as some of Africa’s richest potash deposits.

Collecting Congolese minerals is especially rewarding because the country produces true “world classics” from the Copperbelt and rare suites from Rift volcanics, as well as diamonds from kimberlite fields around Mbuji-Mayi. For more information about the mineral locations in the Congos, click HERE.
