    By using in situ laser combustion, we show for the first time that the range of δ34S for coppercobalt ore sulfides (−1‰ to +18‰) cannot have the same source as diagenetic pyrite (−1‰ to −17‰). We suggest a new epigenetic model for the formation of these spectacular Nchanga orebodies that involves the introduction of
