ARC Research Hub for Basin GEodyNamics and Evolution of SedImentary Systems (GENESIS). This Research Hub aims to undertake simultaneous modelling of deep Earth and surface processes, spanning basin scales to individual sediment grains. The Hub will develop and apply cutting-edge basin simulation approaches to transform the seeding and testing of basin exploration models, extending their viability to complex, inaccessible remote and deep exploration targets. The Hub will fuse multidimensional data into five dimensional basin models (space and time, with uncertainty estimates) by coupling the evolution of mantle flow, crustal deformation, erosion and sedimentary processes, achieving a quantum leap in basin modelling and petroleum systems analysis.Read moreRead less
Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct rele ....Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct relevance to the seismic imaging techniques used by the exploration industry. Finally, the creation of a combined dataset comprising records from ~300 stations will help keep Australia at the leading edge of observational seismology, as other countries (e.g. U.S.) begin to deploy very large seismic arrays.Read moreRead less
The seismic signature of crustal fluids. Fluids are expected to profoundly modify the seismic properties of the cracked rocks of Earth's upper crust (to depths of about 15 km) but there are so far few relevant laboratory measurements. Through the development and application of novel experimental techniques we plan to build a better laboratory-based understanding of the seismic properties of fluid-saturated crustal rocks. The outcome will be an improved capacity to monitor the presence of fluid ....The seismic signature of crustal fluids. Fluids are expected to profoundly modify the seismic properties of the cracked rocks of Earth's upper crust (to depths of about 15 km) but there are so far few relevant laboratory measurements. Through the development and application of novel experimental techniques we plan to build a better laboratory-based understanding of the seismic properties of fluid-saturated crustal rocks. The outcome will be an improved capacity to monitor the presence of fluids in diverse situations ranging from geothermal power generation and waste disposal to earthquake fault zones.

Beneath Bass Strait: linking Tasmania and mainland Australia using a novel seismic experiment. A new low-cost approach based on background seismic energy and earthquake recordings will be used to construct three-dimensional maps of the deep structure beneath Bass Strait. Understanding the broad scale geology of southeast Australia is of national importance because the area is host to an abundance of petroleum, geothermal and mineral resources.
Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achiev ....Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achieve this goal, new methods for constructing multi-arrival wavefronts will be developed and applied to a range of seismic data from Tasmania to produce high resolution images of the crust and upper mantle.

Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which ....Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which magnetofossils contribute to sedimentary palaeomagnetic signals; if magnetofossil occurrences provide information about the marine carbon cycle; and, if magnetofossil chemistry can constrain the depth of sedimentary palaeomagnetic signal acquisition. These are major outstanding questions in sedimentary palaeomagnetism.Read moreRead less

The goal of this project is to develop new techniques for extracting information about the interior structure of the Earth from large geophysical data sets. These methods will be adaptive so that they allow the definition of the physical model to be constrained by the character of the data. The project will utilize advances in computational geometry, nonlinear inversion and interactive computer visualisation to extract robust information from data sets with variable resolving power. The resulting algorithms will be applicable to a wide range of problems in the physical sciences.Read moreRead less
The link between the deep Earth and its dynamic surface. Modelling the two-way interaction of plate tectonics with the actions of erosion and sedimentation gives a fundamentally new view of the dynamics of our planet and the importance of the surface on the deep interior. It will improve our understanding of the formation of sedimentary basins, their evolution and their preservation over geological time.

A fully automated, fully shielded palaeomagnetic system: This project aims to establish the first fully automated and magnetically fully shielded superconducting palaeomagnetic data acquisition system in Australia. Palaeomagnetism is a key research field that has applications to a broad range of pure and applied geoscience disciplines. Australia has been a world leader in this field, including the application of palaeomagnetism to both global and regional tectonic studies. Palaeomagnetic studies demand a labour-intensive process of treating and measuring a large number of samples. The system will significantly enhance the efficiency and accuracy of palaeomagnetic analysis, and thus enhance Australia's research capacity in this and related research fields.Read moreRead less
Down under down under: using multi-scale seismic tomography to image beneath Australia's Great Artesian Basin. Seismic arrays will be deployed in the Great Artesian Basin to image the crust and mantle using distant earthquake and ambient noise sources. This will answer fundamental questions about the tectonic evolution of eastern Australia and elucidate the structure of a region containing significant deep Earth resources.
