Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may ....Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may delineate adjacent plus regionally distributed zones where the deformation event responsible for mineralization is locally present at sufficient intensity to form ore. This would allow targeted deep drilling in ground with no ore close to the surface saving millions in drilling costs and dramatically increasing the financial viability of this industry.

Computationally Modelling a Volcano: Flow and Stability. Mainland Australia is fortunate not to suffer directly from active volcanism. However, this does not mean volcanoes are of little importance. The products of ancient eruptions can define the wealth of a nation. But they are also highly destructive and there are currently 30 active volcanoes capable of generating a tsunami that could affect Australia. Understanding the physical processes using computational models is essential to save lives ....Computationally Modelling a Volcano: Flow and Stability. Mainland Australia is fortunate not to suffer directly from active volcanism. However, this does not mean volcanoes are of little importance. The products of ancient eruptions can define the wealth of a nation. But they are also highly destructive and there are currently 30 active volcanoes capable of generating a tsunami that could affect Australia. Understanding the physical processes using computational models is essential to save lives and help us benefit from their products. This is a relatively new research field and owing to the resources in Australia, our research team has the potential to be at the forefront. There is also the capability to build and impressive research team within the University of Queensland.Read moreRead less

By understanding how, where and why such deposits form, we will assist exploration for future resources of these metals. Insights will also be gained into petroleum resource generation and extraction, the distribution of seismicity and volcanoes in time and space, the problems of underground nuclear waste disposal and sequestration of CO2, and the potential for geothermal energy, with benefits in resource identification and/or hazard assessment in these areas.Read moreRead less
Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large ....Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large-strain theory tailored to rocks experimentally, and to apply it to a pivotal geological problem: shear zone formation. The project will advance our fundamental understanding of the mechanics and energetics of rock deformation and provide a novel tool for the modelling of large deformations.Read moreRead less
Numerical modelling of coupled deformation, fluid flow and heat flow in modern and ancient rifts. Computer modeling of geological processes is increasingly important to mineral and hydrocarbon exploration, to hazard prediction (e.g. earthquakes) and to plate tectonics.

Computer modeling of geological processes is increasingly important to mineral and hydrocarbon exploration, to hazard prediction (e.g. earthquakes) and to plate tectonics. Because it is difficult to understand geological processes from ancient rocks, we will use new computer models to study fluid circulation in an active volcanic fault zone in New Zealand, where many of the parameters obscured in ancient rocks can be measured directly. We will determine processes of fluid migration that contributed to the formation of mineral deposits in ancient rocks, such as those mined in eastern Australia for gold. The project also has implications for discovery and development of energy resources including fossil fuels and geothermal waters.Read moreRead less
