This project aims to develop and test models to evaluate past tectonic processes and configurations in South-east Australia, using both new and existing geological, geophysical and isotopic data. Over the past 550 million years, plate tectonic processes have formed metal-rich mineral deposits in South-east Australia. The project will identify areas of high potential for economically valuable ore deposits, enabling more efficient prioritisation of mineral exploration efforts. This is expected to increase the probability of significant ore deposit discoveries leading to national economic benefit.Read moreRead less

Events through time: eruptions, extinctions, impacts, ore-bodies and orogenies - upgrading the national argon geochronology network. Nine universities and the CSIRO will replace aged and obsolete equipment with new mass spectrometers which will be strategically placed at opposite ends of our continent to improve access for Australian researchers to these instruments for which there is high demand.

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.
The global consequences of subduction zone congestion. This project will use a combination of 3D geodynamic modelling, plate kinematic reconstruction and geological and geophysical synthesis to determine how congested subduction zones influence plate kinematics, subduction dynamics and tectonic evolution at orogen and global scales. The project aims to deliver a transformation change in understanding the links between congested subduction, mantle flow, trench migration, crustal growth, transitio ....The global consequences of subduction zone congestion. This project will use a combination of 3D geodynamic modelling, plate kinematic reconstruction and geological and geophysical synthesis to determine how congested subduction zones influence plate kinematics, subduction dynamics and tectonic evolution at orogen and global scales. The project aims to deliver a transformation change in understanding the links between congested subduction, mantle flow, trench migration, crustal growth, transitions between stable convergent margin configurations and deformation in the overriding plates of subduction zones. Determining these relationships is significant because it will provide dynamic context to interpret the geological record of ancient convergent margins, which host a large percentage of Earth's metal resources.Read moreRead less

Significance
Large amounts of this valuable resource are produced naturally with estimates of production rates of this “gold” hydrogen at least 100 times the annual demand for this critical resource.
Expected Outcomes
Based on improved understanding of the source of natural hydrogen, predictive tools will be developed that will assist in assessing the viability in Australia of hydrogen exploration and engineered retrieval.
Benefits
Ready access to naturally produced hydrogen could enable Australia to replace hydrogen that is currently generated via the use of unabated hydrocarbons.Read moreRead less

Rapid Deployment Seismic Recorders for Interdisciplinary Antarctic Research. We aim to establish an Antarctic-based set of seismic instruments, a mobile facility, to provide data to help predict how ice sheets will evolve and how the continent under the ice sheets will respond to changes in ice load. Our approach to tackling such significant questions is innovative, and makes use of newly available, rapid deployment instruments that may be deployed in ice by a small team with light logistics. ....Rapid Deployment Seismic Recorders for Interdisciplinary Antarctic Research. We aim to establish an Antarctic-based set of seismic instruments, a mobile facility, to provide data to help predict how ice sheets will evolve and how the continent under the ice sheets will respond to changes in ice load. Our approach to tackling such significant questions is innovative, and makes use of newly available, rapid deployment instruments that may be deployed in ice by a small team with light logistics. Outcomes will include maps of sub-ice sediments and 3D images of the deep Earth. The facility will thus enable new knowledge relating to major ice sheets. Interdisciplinary use of the research will benefit Australia through an improved ability to plan for future sea level rise in areas with large coastal populations.Read moreRead less

Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale mid-way between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.Read moreRead less
