Abstract
The Cu-Co deposits of the Nchanga Mine in the Zambian Copperbelt are consistently hosted by a arenites or arkoses with mineralization progressing for short distances into overlying shales. The ore horizons show a consistent association with flat-lying structures and in the Upper Orebody, are developed with thrust controlled antiformal structures. Hydrothermal alteration includes phlogopite ± sericite followed by dolomite precipitation and available stable δ34S of sulfides and δ13C data for carbonates are consistent with “in situ” thermochemical reduction of a sulphate rich fluid. The new data reported here suggest a strong link between Cu and Co ore formation in the Zambian Copperbelt and the development of structures during basin inversion and the onset of the Luffilian orogeny.
