The origin, transport and deposition of Fe, Cu and Au in the Earth’s crust: An integrated geochemical approach to understanding ore-forming processes in Fe oxide Cu-Au systems

Funding for 2006: $39,009 (Monash University Logan Research Grant)

The origin of the fluids and metals in Proterozoic Fe oxide Cu-Au systems is controversial, and new data suggest that both magmatic and metamorphic fluids were associated with mineralisation, but their relative significance is unknown. This project will attempt to overcome these problems by integrating the geochemical and radiogenic isotope characteristics of fluids from different sources with advanced geochemical modelling of ore-forming processes to determine the significance of each component for ore deposition. This work will reinterpret ore-forming processes involving Fe, Cu and Au, and will obtain predictive geochemical and mineralogical data for ore deposit styles.
