Tectono-metamorphic evolution of the Giterama-Gatumba-Mwendo area (Rwanda): implications for the geodynamic framework and the metallogenesis of Nb-Ta-Sn-W granite-related mineralization of the Karagwe-Ankole Belt. KU Leuven

Philippe Muchez
Geology

This PhD research investigates the tectono-metamorphic history of the Karagwe-Ankole Belt in Central Africa. Earlier studies in this Mesoproterozoic belt have focused on the magmatic events and granite-related Sn-Nb-Ta-W-Au metallogenetic province, and only to a lesser extent on the sedimentological and tectono-metamorphic aspects. Additionally, not all results of these studies could be incorporated into one consistent geological model, ...

Metallogenesis of the Cu-Co deposits in the Central African Copperbelt, information from REE patterns and the Lu-Hf isotopic system. KU Leuven

Philippe Muchez
Division of Geology

This PhD thesis is centered on the Central African Copperbelt, a Neoproterozoic stratiform Cu-Co ore province, and consists of three main parts. The first part focuses on the geotectonic evolution of the basement units in the vicinity of the Katanga basin that hosts the ore deposits. The second part uses rare earth element patterns in gangue carbonates associated with the ores as proxies for hydrothermal mineralization-related ...
