Abstract

Summary

Based on the interpretation of space imagery, in the western part of the metallogenic province of Lake Victoria in Tanzania the Sukumaland ore-magmatic system of concentric-zonal structure has been distinguished. It is formed by a group of arched greenstone belts (GSB) and associated gold deposits. They form two arc-like branches: the internal and external branch, differing in their composition and structure. The internal arc is represented by the Rwamagaza and Kahama GSB with gold deposits of Tulawaka, Buckreef, Mawe-Meru, Tembo, Bulyanhulu. The external arc is represented by Geita and Mabale-Buhungurica GSB with gold deposits of Ridge-8, Nyankanga, Geita, Matandani, Kukuluma, Nyanzaga, Kitongo, Golden Ridge. Their huge gold potential (over 50 million ounces of gold) stipulates for the urgency of the study of this gigantic structure. The most interest is the kernelpart of the ore-magmatic system, where occurrences of volcanism and gold or other mineral deposits ha ven’t been indicated yet, but a tectonic pattern of its structural elements indicates its significant ore potential. It is assumed that the ore-magmatic system has originated and evolved as result of a complex multi-stage ore-magmatic process under the influence of upward flows of deep fluids due to the long-term functioning of a zone with anomalously heated mantle in that area. During further geological explorations it is recommended to take into account the predicted availability of a common integrated sustained ore-magmatic system and their structural features.
