Granite-related versus orogenic mineralisation: inisghts from the W, Sn and Au mineralisation in Rwanda.

W, Sn and Au mineralization are interpreted to form by magmatic or metamorphic and orogenic processes, which has often led to an intense debate on their origin. The Karagwe-Ankole Belt in Rwanda contains W, Sn and Au mineralized quartz veins and enables to study and compare in detail the different geological and geochemical characteristics of these three types of mineralization. The aim of the research project is to determine 1) the structural setting and timing of the different mineralized quartz veins, 2) ore formation in the geodynamic evolution of the orogen, 3) the geochemistry and origin of the mineralizing fluids, 4) the importance of differentiation and fractionation of felsic melts as a source of fluids and metals and 5) the interaction of these fluids with the host rock, fluid mixing and their role in mineral precipitation.
