Base Metal Ore Deposit Evolution And Geodynamics In The Central African Copperbelt

Ore deposits in the Central African Copperbelt formed during several stages of the evolution of the Katanga sedimentary basin. The first mineralization phase occurred during diagenesis, either early or late depending on the ore district. A second major mineralization phase occurred during late Proterozoic metamorphism associated with the Lufilian orogeny (e.g. Nchanga deposit, Zambia). Several syn- to post-orogenic polymetallic and Cu-Ag deposits also occur in the Lufilian orogen (e.g. Kipushi and Dikulushi, DRC).
