Abstract

Prospection was performed on the tin mineralized belt in Mwanza and Kongolo areas of Katanga, DR Congo. Most of deposits in Katanga areas are related to the granites which are located in Kibaran belt in NE and SW trends of mid Proterozoic. Metasedimentary rocks in the Kibaran belt are intruded by granites, and tin, niobium and tantalum deposits are especially developed along with tin-granite. Cassiterite, coltan and gold are developed in the pegmatite, quartz vein and greisen in related to the tin-granite in Mwanza and Katanga areas, and they are exploited by artisan in the smale scale. And we conducted the works with the alluviums and stream sediments in the case of no outcrops. With the results of analysis of samples, we will choose a few potential mineralized zones and continue to prosepect precisely.

Keywords Tin, Nb, Ta, Coltan, Pegmatite, Greisen, DR Congo
