Dating ore-remobilising fluids in the Olympic Cu-Au province

Use novel tools to shed more light on the most prolific mineral province of South Australia.

Dating the apatite /calcite (+ iron-oxides, not in the picture) provides constraints on the timing of fluid remobilisation. View larger image.

The Olympic Cu-Au Province is one of the most economically profitable regions of Australia, hosting world-class IOCG deposits. Although the Olympic Province has extensively been studied, there is growing evidence that important but largely undiscovered fluid remobilization events affected the area, which has implications for the discovery potential of ore deposits.

This project aims to apply petrochronology and thermochronology to in-situ date and geochemically characterize fluid remobilisation using several novel techniques that were recently developed / implemented by our research groups (e.g. dating phosphates, carbonates and iron oxides). Samples will be sourced from drill core near IOCG deposits via industry partners.

The results from this project will inform on mineral deposit prospectivity and assist with narrowing down exploration space in relation to targeting for drilling.
