Abstract

The huge sediment-hosted copper deposits at Olympic Dam and Mount Isa are of unusual types. They formed epigenetically from hydrothermal fluids, as did several other important Australian copper deposits in sedimentary strata. Ore within a palaeoweathering zone at the top of a red-bed unit at Mount Gunson appears to have formed at relatively low temperatures over a long period and to have incorporated biogenic sulfur. Bedded-disseminated mineralization, which is wide-spread in South Australia, formed by reaction of cupriferous fluids with biogenic H2S and early diagenetic iron sulfides. To date, stratiform copper mineralization has not been of major economic significance in Australia.
