Geochronology of the Nchanga Granite, and constraints on the maximum age of the Katanga Supergroup, Zambian Copperbelt

Armstrong, Richard; Master, S; Robb, L


The age of the Neoproterozoic Katanga Supergroup, which hosts the stratiform Cu-Co deposits of the Central African Copperbelt, has not been well constrained. The Nchanga Granite, the youngest pre-Katangan intrusion in the Copperbelt basement, is nonconformably overlain by sedimentary rocks of the Katanga Supergroup, a relationship that is well exposed in the open pit at Nchanga Mine, Zambia. Previous attempts at dating the Nchanga Granite using the K-Ar and Rb-Sr systems have given only younger...[Show more]
