New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycl ....New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycle, blurring source-sink relationships, b) zircon may be absent in mafic lithologies thus biasing investigations. In this work K-feldspar & apatite provenance investigation will be undertaken on a state wide basis and include case studies in the Yilgarn Craton and Canning & Northern Carnarvon Basins.

Resolving the influence of intraplate orogenesis on continental margin tectonics. Novel, multi-dating of continental sedimentary rocks will be undertaken to examine the effects of a high sediment flux from an enigmatic, major mountain-building event on a distant continental margin. This will expand our understanding of the range of tectonic influences between continental interiors and margins and onshore resource potential.
Developing a geomorphological framework to underpin management decision-making on the Great Barrier Reef. The paucity of data on coral reef growth histories inhibits attempts to integrate regional reef growth data into coral reef management - despite the major influence on habitat type and diversity. This project will gather such data for one region of the Great Barrier Reef, and develop such datasets to support future reef management decision-making.

Summary
Single-grain optically-stimulated luminescence and dosimetry instruments to service the Sydney metropolitan and greater New South Wales region. This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on ....Single-grain optically-stimulated luminescence and dosimetry instruments to service the Sydney metropolitan and greater New South Wales region. This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on established collaborations in Australia, Antarctica and the south-west Pacific and encourage new collaborations with south-east Asian, Egyptian and Argentinean researchers, which will promote Australian research on a world stage. The use of this equipment will also pioneer new dating methodologies to further enhance Australia's place at the forefront of geochronology.Read moreRead less
A one million year record of relative sea-level, climatic and environmental changes - Aeolianites of the southern Australian continental margin. This project will (1) further refine two dating methods that will revolutionize Australia's capacity to date geological and archaeological events; (2) ensure that Australia remains in the forefront in applied geochronology and that a sufficient level of technical expertise remains within the country; (3) examine the sensitivity of coastal environments t ....A one million year record of relative sea-level, climatic and environmental changes - Aeolianites of the southern Australian continental margin. This project will (1) further refine two dating methods that will revolutionize Australia's capacity to date geological and archaeological events; (2) ensure that Australia remains in the forefront in applied geochronology and that a sufficient level of technical expertise remains within the country; (3) examine the sensitivity of coastal environments to rapid climate and sea-level changes; (4) increase public awareness of the scientific basis for the unique nature of Australia's coastal landscapes; and (5) may also assist in the exploration of strategically important minerals.

Obduction, lithospheric flexure and basin formation. The proposal aims to investigate the links between hydrocarbon basins and obduction, or emplacement of oceanic crust onto continental margins. Obduction of the Samail Ophiolite of Oman onto the Arabian Peninsular at a time of the world's largest hydrocarbon accumulation, requires a causative relationship. This event remains poorly constrained and controversial, and therefore limits exploration models for hydrocarbons. Understanding the dynamic ....Obduction, lithospheric flexure and basin formation. The proposal aims to investigate the links between hydrocarbon basins and obduction, or emplacement of oceanic crust onto continental margins. Obduction of the Samail Ophiolite of Oman onto the Arabian Peninsular at a time of the world's largest hydrocarbon accumulation, requires a causative relationship. This event remains poorly constrained and controversial, and therefore limits exploration models for hydrocarbons. Understanding the dynamics of obduction of ocean crust onto a passive continental margin and the resultant flexural basin is of major global importance. This proposal addresses this issue in the superbly exposed Arabian Pensinsular, applying geochronology, basin analysis and basin modelling techniques.Read moreRead less
Chronostratigraphic and tectonothermal history of the northern Capricorn Orogen: constructing a geological framework for understanding mineral systems.

Tropical sand beach ridges - a new approach to palaeotempestology. Investigations of sand beach ridges in northern Australia will considerably reduce the impact of future tropical cyclones on communities. These ridges record a detailed history of cyclones over the past 5,000 years. Due to the great length of record we will now be able to identify cycles of cyclone activity, which will allow us to better predict the consequences of these hazards under an enhanced greenhouse climate and reduce the ....Tropical sand beach ridges - a new approach to palaeotempestology.

Developing a new tectonothermal and mineralization history for the Capricorn Orogen, Western Australia: Assisting mineral exploration in greenfields terrains. Successful exploration models rely on the development of a reliable geological framework through which to understand the specific processes responsible for the formation of economic ore deposits. A framework cannot be constructed without robust age data.

Successful exploration models rely on the development of a reliable geological framework through which to understand the specific processes responsible for the formation of economic ore deposits. A framework cannot be constructed without robust age data. This Project will apply advanced geochronology, combined with regional- and deposit-scale field mapping, to formulate a new and improved stratigraphic and tectonic framework for a prospective greenfields region in Western Australia. Outcomes from this Project will lead to more effective exploration models and thereby better exploration targeting. Reducing uncertainty and risk in exploration is key to the discovery and development of deep Earth resources. Read moreRead less
