Structural analysis of naturally deformed rock will be used to investigate the origin, physical characteristics and frictional behaviour of naturally formed discontinuity surfaces. Discontinuities in naturally deformed rock masses are typically altered and infilled with complex combinations of mineral matter and are a major control on the rheology, including strength and stability, of rock masses in engineering excavations. By combining structural geology techniques and laboratory experiments, and with reference to existing data on field-scale rock mass deformation derived from engineering rock mechanics investigations, a methodology for predicting rock mass rheology from fundamental geological observations will be devised and tested.Read moreRead less
Microscale evolution of deformed rocks and glaciers. Scientific outcomes from this research have significant implications for predictions on material properties and are applicable to rock behaviour in mineralised systems, a focus of Australia's minerals industry, and the development of new materials for the Australian manufacturing industries. It will help maintain Australia's excellent international research reputation in the fields of microstructural geology and glaciology.
Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the ....Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the northern and southern Australian cratons. By constraining models of crustal evolution and architecture, the project will underpin future mineral exploration programs in this highly prospective greenfields region and define the role of the Musgrave Block in the assembly of Proterozoic Australia.Read moreRead less
Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and ....Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and geophysical tools to develop a comprehensive model for the tectonic evolution of the Gawler Craton. The project will constrain the development of the Gawler Craton in the context of Precambrian Australian evolution, and offer insights into universal processes of lithosphere formation, growth and stabilisation.Read moreRead less
Microstructural analysis using integrated experiments and numerical modelling. Microstructures related to nano-materials and visible up to the scale of a thin section, are important tools for any material scientist, geologist or glaciologist. Microstructural evolution underpins how these disciplines unravel grain-scale structures, deformation conditions and mechanisms to estimate the intensity or amount of deformation. This project will allow us to better interpret microstructural evolution, in ....Microstructural analysis using integrated experiments and numerical modelling. Microstructures related to nano-materials and visible up to the scale of a thin section, are important tools for any material scientist, geologist or glaciologist. Microstructural evolution underpins how these disciplines unravel grain-scale structures, deformation conditions and mechanisms to estimate the intensity or amount of deformation. This project will allow us to better interpret microstructural evolution, in a range of natural, organic and composite materials, by using integrated laboratory experiments and numerical simulations. With these results we will model the conditions that prevail in composite materials, in glaciers and apply them to processes operating in of the Earth's crust.Read moreRead less

Earth comprises systems of enormous complexity that sustain all life and control the distribution of mineral, energy and water resources. Thus understanding these dynamic systems provides the key to sustainable resource usage. The aim of The Earth System Dynamics Network is to facilitate scientific interactions through establishment of an earth and environmental sciences grid that links national and regional data assets with high performance computing through open sourced middleware. The result will be an unparalleled predictive capacity for complex Earth systems. The outcome will be confidence in the knowledge that underpins our decisions as stakeholders to keep Australia sustainable.Read moreRead less
Southern gateways - the icehouse cometh: Eocene to Oligocene evolution of southeast Australia. The 50 to 30 million years old strata of southeastern Australia have great economic importance for Australia. Most of the gas and oil extracted in the region comes from strata of this age. The research will lead to better age constraints on these reserves, thus enhancing petroleum prospectivity in the area. The global environment changes from 50 to 30 million years charted in this project will lead ....Southern gateways - the icehouse cometh: Eocene to Oligocene evolution of southeast Australia. The 50 to 30 million years old strata of southeastern Australia have great economic importance for Australia. Most of the gas and oil extracted in the region comes from strata of this age. The research will lead to better age constraints on these reserves, thus enhancing petroleum prospectivity in the area. The global environment changes from 50 to 30 million years charted in this project will lead to a better understanding of the geological record of greenhouse-icehouse change. Knowledge of the nature of this change in the past is critical to predicting how our climate is going to behave in the future.Read moreRead less

Modeling slab pull forces and lithospheric deformation provides a new insight in the dynamics of plate tectonics. Unraveling the self-consistent formation of faults, rifts, shear zones and up to passive margin will further the understanding of our planet. Furthermore the application of these models to specific geological contexts will support the exploration and assessment of inaccessible Earth's resources, such as hydrocarbons pools, located along the deep Australian continent margins, and diamonds and ore deposits, associated with continental shear zones, which potential is still to be fully discovered.Read moreRead less

The purpose of this research is to determine the positions of atoms in crystals and nano-crystals. We have developed a theory that shows how to extract all of the information required to determine atomic positions from such crystals and we have carried through initial successful tests on simple materials. In particular, we have found that crystallographic phase, hitherto not directly measurable, can in fact be extracted uniquely from a single electron diffraction pattern. This constitutes a solution to the phase problem in crystallography. It is now our aim to develop this method into a routine technique.Read moreRead less
