Dynamic earth models for frontier diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in ....Dynamic earth models for frontier diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in under-explored regions such as Australia. Significant benefits from the project will be the reduction of economic risks in diamond exploration, the training of a researcher in exploration geodynamics, and understanding the link between supercontinents and mantle upwelling.Read moreRead less
Magmatic response to slab deformation and implications to ore formation. The uneven distribution of ore deposits in magmatic arcs is poorly understood. This project aims to provide new strategies for more effective mineral targeting by testing the hypothesis that anomalous magmatism enriched in metals reflects particular styles of deformation, such as tears in subducting slabs. We will use geophysical modelling to constrain slab structure along the northern boundary of the Australian plate, and ....Magmatic response to slab deformation and implications to ore formation. The uneven distribution of ore deposits in magmatic arcs is poorly understood. This project aims to provide new strategies for more effective mineral targeting by testing the hypothesis that anomalous magmatism enriched in metals reflects particular styles of deformation, such as tears in subducting slabs. We will use geophysical modelling to constrain slab structure along the northern boundary of the Australian plate, and geochemical data to establish spatio-temporal links with anomalous magmatism and ore deposits. By identifying the geochemical fingerprint of tear-related magmatism, outcomes are expected to benefit geoscience research and mineral exploration by providing context to similar rock associations in mineral-rich provinces.Read moreRead less

Summary
The dynamics of continent deformations. Modeling the coupling of subducting oceanic plates and deforming continents provides a fundamentally new view of the dynamics of our planet. It will improve an understanding of the formation of basins in continent interiors and their evolution over geological times.
Lifting the lid on a supercontinent. This project will reveal the time-integrated growth and collapse of a supercontinental orogen in order to advance knowledge on the influence that mountain-building events have on the cycling of materials between the major near surface Earth reservoirs. Given that this cycling is key to understanding deep-time climate and the formation of mineral resources the outcomes of this study will have important economic benefits for targeting mineral resources and plac ....Lifting the lid on a supercontinent.

Indo-Australian Plate Active Tectonics Program. The Indo-Australian Plate Active Tectonics Program investigates fundamental questions in geodynamics using the unique record of landscape evolution in Australia. In this project the origin of iconic landscapes such as the Lake Eyre Basin and the Flinders Ranges will be addressed to explore the nature of the couplings between surface deformation and flow in the upper mantle, and between surface processes and tectonic activity.
A unified model for the closure dynamics of ancient Tethys constrained by geodesy, structural geology, argon geochronology and tectonic reconstruction. The project will elucidate complex planetary dynamics involved in the interaction of the oceanic plates with the continental crust. Such aspects underpin the ability of geoscientists to effectively simulate and model, impacting on issues ranging from forecasting earthquakes to how to conduct greenfields exploration for energy and mineral resource ....A unified model for the closure dynamics of ancient Tethys constrained by geodesy, structural geology, argon geochronology and tectonic reconstruction.

How the complexity of continental breakup controls ocean circulation. This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events. This project aims to unravel their role relative to other drivers for example carbon dioxide (CO2). Unravelling the influence of seaway opening co ....How the complexity of continental breakup controls ocean circulation. This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events. This project aims to unravel their role relative to other drivers for example carbon dioxide (CO2). Unravelling the influence of seaway opening compared with declining CO2 in the onset of Antarctic and Northern hemisphere glaciation will enable more accurate future climate simulations. The project will also give international exposure and training to the next generation of numerically adept geoscientists and oceanographers.Read moreRead less
Supercells and the supercontinent cycle. This is a new approach to understanding how the Earth works, at a global-scale and billion-year perspective. In particular it seeks to understand why continents come together as supercontinents, then drift away again. The work has implications for copper-gold exploration on the Australian continent because it has relevant predictive capacity.
Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to ad ....Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to add increased value over future decades. This project enhances the probability that at least one other ore-body of this type will be discovered. Such discoveries contribute directly to the wealth of Australia through export earnings and accelerate the development of regional infrastructure and new technological development.Read moreRead less
Deciphering the tectonic record of the early Earth. This project aims to decipher how and why plate tectonics emerged, and how any precursor tectonic system modulated planetary heat loss. The project expects to generate new knowledge regarding the tectonic record of the early Earth using pressure–temperature–age constraints from truly ancient (2.8–4.0 billion year old) metamorphosed rocks worldwide. Expected outcomes of this collaborative international project include the development of a concep ....Deciphering the tectonic record of the early Earth. This project aims to decipher how and why plate tectonics emerged, and how any precursor tectonic system modulated planetary heat loss. The project expects to generate new knowledge regarding the tectonic record of the early Earth using pressure–temperature–age constraints from truly ancient (2.8–4.0 billion year old) metamorphosed rocks worldwide. Expected outcomes of this collaborative international project include the development of a conceptual geodynamic model for the early Earth. This should provide significant benefits in permitting a better understanding of the where and why of Australia’s natural resources, in training a new generation of Earth system scientists, and in broadening public awareness of fundamental Earth science.
