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
Understanding the Sibao Orogenic Belt in South China: A Part of the Rodinian Supercontinent Assembly Adjacent to Australia. The Sibao Orogenic Belt (SOB) in South China is regarded as one of the worldwide 1300-1000 Ma mountain belts that record the assembly of the supercontinent Rodinia. However, recent work suggests that some of these mountain belts, including the SOB, were probably active until 900 Ma, thus questioning parts of the early Rodinia reconstructions. In this study we aim to deter ....Understanding the Sibao Orogenic Belt in South China: A Part of the Rodinian Supercontinent Assembly Adjacent to Australia. The Sibao Orogenic Belt (SOB) in South China is regarded as one of the worldwide 1300-1000 Ma mountain belts that record the assembly of the supercontinent Rodinia. However, recent work suggests that some of these mountain belts, including the SOB, were probably active until 900 Ma, thus questioning parts of the early Rodinia reconstructions. In this study we aim to determine the ages, and geochemical and structural characteristics of key tectonic units in the SOB. This will lead to a better understanding of the assembly process of Rodinia, and events occurring in continental blocks adjacent to Australia at that time.Read moreRead less
Tectonic links between the Musgrave Province and the North Australian Craton: correlations, event chronology, and tectonothermal regimes. Developing effective mineral exploration strategies relies on data-rich tectonic models that seek to explain the full history of a terrain. In the Australian context the tectonic evolution of the Musgrave Province is a key focus of the minerals industry due to its widely recognised potential for base-metal mineralisation. This project will develop tectonic mod ....Tectonic links between the Musgrave Province and the North Australian Craton: correlations, event chronology, and tectonothermal regimes. Developing effective mineral exploration strategies relies on data-rich tectonic models that seek to explain the full history of a terrain. In the Australian context the tectonic evolution of the Musgrave Province is a key focus of the minerals industry due to its widely recognised potential for base-metal mineralisation. This project will develop tectonic models that encompass the evolution of the Musgrave Province and the adjacent North Australia Craton. The outcomes of the project will reduce risk to mineral explorers and make an important contribution to the broader question Australia's Proterozoic evolution.Read moreRead less
