The link between cratonic roots, redox state, and mantle geodynamics. This project aims to understand the role of Earth's redox state on the geodynamic evolution of continental cratonic roots. Cratonic roots form strong, buoyant rafts upon which Australia's oldest crust and mineral deposits survived. Cratons preserve a record of planetary-scale chemical shifts, including the rise of surface oxygen, but it is unclear how these redox shifts themselves affected lithospheric processes.

This project aims to understand the role of Earth's redox state on the geodynamic evolution of continental cratonic roots. Cratonic roots form strong, buoyant rafts upon which Australia's oldest crust and mineral deposits survived. Cratons preserve a record of planetary-scale chemical shifts, including the rise of surface oxygen, but it is unclear how these redox shifts themselves affected lithospheric processes. This project integrates new developments in geochemistry, geophysics, and geodynamics, to map the geochemical state and structure of cratonic roots, aiding mineral exploration, and also shedding light on the processes that modify, mineralise, and sometimes destroy cratonic roots.Read moreRead less
Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models ....Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models will subsequently be developed, to form an effective characterisation of the geologic structure of the craton and its margins. These models will provide enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an improved understanding of mineral resource potential. Read moreRead less
Craton modification and growth: the east Albany-Fraser Orogen in three-dimensions. The objective of this work is to achieve new, synergistic techniques for delineating the three-dimensional structure of the east Albany-Fraser Orogen in Western Australia, and the lithospheric structure below it. These methods will guide understanding of the potential for mineral resources in this region with little surface geological exposure.
Structure of crust on Mars. This project aims to start a new multidisciplinary field linking impact physics and seismology.

This project involves numerical modelling of meteoroid impact-induced seismic activity on Mars, using the state-of-the-art hydro-code, a national supercomputing facility, and knowledge built on the meteorite hunting by the Dessert Fireball Network. High-resolution numerical results will aid the analyses of impact-seismic data obtained by the forthcoming InSight mission to Mars (in 2018) with a single important aim, to decipher the crustal structure of Mars, the planet that is the most similar to the Earth in our solar system.Read moreRead less

Summary
Impact processes and evolution of the Martian crust. The project aims to define the crustal structure of Mars, using three-dimensional hydrodynamic modelling, experiments and geophysical data obtained from Mars. This will be achieved by the analysis of impact-related seismic data obtained by the forthcoming mission to Mars, along with already available remote sensing data of Mars. This project will start a new multidisciplinary field linking numerical impact physics and seismology.

This project aims to advance knowledge on magma transport mechanisms through the Earth’s lithosphere, and boost predictive capacity to discover new ore deposits. Using field surveys, three-dimensional reflection seismic data, laboratory experiments and rock fracture mechanics, this project will investigate where, how and why, narrow finger-like conduits form in lithosphere-scale magma plumbing systems. The project expects to generate new knowledge on the formation and location of highly valuable ore deposits of nickel, copper, cobalt and platinum group elements, which are preferentially trapped in poorly understood, finger-like magma conduits. Anticipated outcomes of the project include fundamental insights into how magma transport dynamics control traps for magmatic sulfide ores as well as equipping mineral explorers in targeting their search for these important, but hard to find, ore deposits, benefitting society through future discoveries of economically strategic, new commodities.Read moreRead less
