Petroleum exploration – we are utilising novel molecular (e.g. 3-dimensional GC X GC TOFMS) and isotopic approaches to elucidate the source and geological age of organic matter, establishing new biodegradation proxies in petroleum reservoirs, establishing migration and accumulation histories of petroleum and correlating oils-oils and oils-source rocks. New organic and inorganic proxies to establish the precise age source of petroleum are being established. The source of oil associated with spills, shipping operations and natural seepages. Application of organic geochemistry is applied to conventional and unconventional hydrocarbon reserves as well as mineral systems. A wide range of global petroleum systems of varying ages are currently under investigation including but not limited to: Australia (Perth, Canning, Vulcan, Bonaparte, Carnarvon and Georgina Basins) Western Canada, China, Indonesia, the Arctic, India and Pakistan. The deep-subsurface biosphere has recently become a focus of international research. Microbial habitats have been shown to extend to significant depths beneath the Earth’s surface. While microbial life in sub-seafloor sediments has received much attention, little is known about deep-subsurface bacterial behaviour in the presence of petroleum and minerals. Petroleum reservoirs can be regarded as natural bioreactors.
Mineral exploration – It has long been noted that organic matter (OM) is often closely associated with many major classes of mineral deposit, but the role of organics in ore formation has historically been under-explored. The CSIRO Organic Geochemistry of Mineral Systems (OGMS) Cluster project was formed in 2011 under the Minerals Down Under Flagship, and was led by Curtin University in collaboration with the University of Western Australia, the University of Melbourne, the Australian National University and a number of international researchers. The Cluster project ended in 2015, but work in this area is continuing with a number of grants and research fellowships having been awarded. The OGMS Cluster project has aimed to answer questions including: what is the composition of OM associated with major mineral systems? What influence did this OM have on the transport and/or deposition of metals? How has the formation of ore deposits affected the associated OM (e.g. thermal maturity, radiolytic alteration)? What role can OM play in ore deposit exploration? Study sites include major deposits of lead and zinc (Here’s Your Chance – Australia), gold (Cosmo Howley, St. Ives & Wiluna – Australia and Macraes – New Zealand) and uranium (Mulga Rock – Australia). A range of techniques have been applied including traditional analysis of extractable OM, hydrofluoric acid digestion to release OM bound within the mineral matrix (Bitumen II), hydropyrolysis (HyPy), Micro-Scale Sealed Vessel (MSSV) pyrolysis, Raman spectroscopy and theoretical modelling. A gas chromatography – inductively coupled plasma mass spectrometry (GC-ICPMS) system has been developed for compound-specific measurement of ?34S – only the third such system worldwide.
