Abstract
Geological regions with abnormally high endowment in metals appear to have resulted from the fortunate juxtaposition in space and time of numerous, possibly exceptional, processes. The Archean eastern Yilgarn Craton, Western Australia is such a region. The approach taken in this Special Issue is to consider the gold mineral system in the eastern Yilgarn Craton in terms of a series of integrated components, referred to by Price and Stoker (2002) and Barnicoat (2007) as the Five Questions: 1. What are the geodynamic and P-T histories of the system? 2. What is the architecture of the system? 3. What are the fluid reservoirs? 4. What are the fluid flow drivers and pathways? 5. What are the metal and sulphur transport and depositional processes? In order to better understand these components and the geological processes which define them, a range of scales needs to be considered. At each scale, however, the relative benefits of considering any one of the five components are varied. For example at the terrane scale, an analysis of the geodynamics and architecture provides most insight, whereas an analysis of deposition mechanisms is best conducted at a deposit scale. This Special Issue focuses specifically on the first two questions, in order to provide a greater understanding of the geodynamic and architectural processes which have contributed to the elevated endowment of gold in the eastern Yilgarn Craton. The papers in this Special Issue reports some of the results produced by the Predictive Mineral Discovery Cooperative Research Centre (pmd*CRC, www.pmdcrc.com.au), a research centre funded for seven years by the Australian Government, universities and mineral exploration industry partners.
