The Mount Isa deposit is either regarded as sediment-hosted stratiform deposit or as submarine exhalative deposit by many mining geologists. To investigate this problem from the geochemical point of view, chalcopyrite (7 samples), pyrite (6 samples), sphalerite (1 sample), and pyrrhotite (1 sample) from the copper orebody of the Mount Isa deposit have been analyzed for minor elements by atomic absorption spectroscopy. The comparison of the minor element distribution in pyrites from the Mount Isa deposit, the kuroko deposits, the Kieslarger type deposits and the Lower Jurassic black shale of Yorkshire, England, shows that the Co and Ni contents of pyrite from the Mount Isa ores are almost same with those of the Kieslarger type deposits.
The other features of the minor element contents in pyrite from the Mount Isa deposit include comparatively enriched Bi and poor Mn, compared with those of the kuroko and Kieslarger type deposits. The same tendencies are also observed in chalcopyrite from the Mount Isa deposit.
