Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future ma ....Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future major discoveries. This project addresses the pressing need for new data and improved exploration techniques to enable industry to target new discoveries. As the Southern Cross district is located in remote communities such discoveries also have major benefits for regional Australia.Read moreRead less
A Multi-Isotope, Multi-Mineral Approach to Chronology of Deformation, Metamorphism and Gold Mineralisation in the Eastern Goldfields Province, Western Australia. Following recent research, an excellent framework is emerging for the evolution of the Eastern Goldfields Province. However, the weak link remaining is the precise timing of post-depositional geological events. The majority of available ages are equivocal because only single ?non-robust? isotope systems were used. This project will be t ....A Multi-Isotope, Multi-Mineral Approach to Chronology of Deformation, Metamorphism and Gold Mineralisation in the Eastern Goldfields Province, Western Australia. Following recent research, an excellent framework is emerging for the evolution of the Eastern Goldfields Province. However, the weak link remaining is the precise timing of post-depositional geological events. The majority of available ages are equivocal because only single ?non-robust? isotope systems were used. This project will be the first to take a multi-isotope and multi-mineral approach to constrain the temporal framework for the geological history of the Province. It will also provide an unequivocal guide to the robustness of the various isotopic methods and enable a careful reassessment of existing data and identification of appropriate methodology for future research.Read moreRead less
