The genesis of the Mount Isa Cu-Pb-Zn system, northern Australia, is highly debated. Three metallogenic models have previously been proposed to explain the close spatial relationship between a world-class Cu and Pb-Zn deposit: (1) ca. 1650 Ma syngenetic Pb-Zn mineralisation that has been re-mobilised and overprinted by ca. 1520 Ma epigenetic Cu …
