Summary
High Performance Computing Infrastructure Upgrade. The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity.

The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity. The combination of a large number of very fast processors and a very fast interconnect makes this facility ideal for modelling and solving science and engineering problems beyond the scope of installed HPC systems. The facility will be linked to other HPC systems in Victoria and across Australia to create an evolving cluster computing "meta-centre" that links computing resources together.

Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water wher ....Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water where geophysical prospecting methods are unreliable. Model-driven "exploration geodynamics" methods such as those we are developing will be needed to support traditional exploration techniques in these areas.Read moreRead less
Was there an unusual environment with equally remarkable inhabitants in Early Cretaceous southeast Australia? After more than two decades of effort, there is strong evidence that Early Cretaceous southeastern Australia was inhabited by a remarkably diverse polar terrestrial vertebrate fauna adapted to the coldest environment known to have existed anywhere in the late Mesozoic. In this unusual terrestrial habitat for that time, temnospondyl amphibians and allosaurid dinosaurs survived long ....Was there an unusual environment with equally remarkable inhabitants in Early Cretaceous southeast Australia? After more than two decades of effort, there is strong evidence that Early Cretaceous southeastern Australia was inhabited by a remarkably diverse polar terrestrial vertebrate fauna adapted to the coldest environment known to have existed anywhere in the late Mesozoic. In this unusual terrestrial habitat for that time, temnospondyl amphibians and allosaurid dinosaurs survived long after becoming extinct elsewhere. Here, too, are found what may be the oldest known and yet remarkably advanced placental mammals, the group to which we belong. To further corroborate or refute these hypotheses, some of which are highly contentious, is the aim of this project.Read moreRead less
Three dimensional computational models of geological basin and hinterland evolution incorporating lithospheric mantle and surface processes. Petroleum exploration in deepwater areas offshore Australia is becoming increasingly important as more accessible, shallow water oil reserves near exhaustion. Geological simulation is an important tool for understanding deep water basins where geophysical imaging techniques are less effective. This project will develop 3D computational models relevant to un ....Three dimensional computational models of geological basin and hinterland evolution incorporating lithospheric mantle and surface processes. Petroleum exploration in deepwater areas offshore Australia is becoming increasingly important as more accessible, shallow water oil reserves near exhaustion. Geological simulation is an important tool for understanding deep water basins where geophysical imaging techniques are less effective. This project will develop 3D computational models relevant to understanding the development and evolution of geological basins and the sediments that fill them. The models will be integrated with available offshore data for potentially prospective Australian basins in the Northwest Shelf and the Southern Australian margin.Read moreRead less
The eruption, emplacement and characteristics of extremely large volume pyroclastic flow deposits (ignimbrites). Pyroclastic flows are hot, turbulent, flows of volcanic gas, pumice, rock debris and fine ash often produced during major explosive volcanic eruptions. Most historic and researched events have been mostly small volume examples. In this research we propose to investigate the characteristics of 3 extremely large volume (>1,000 km3) pyroclastic flow deposits in the Andes of South America ....The eruption, emplacement and characteristics of extremely large volume pyroclastic flow deposits (ignimbrites). Pyroclastic flows are hot, turbulent, flows of volcanic gas, pumice, rock debris and fine ash often produced during major explosive volcanic eruptions. Most historic and researched events have been mostly small volume examples. In this research we propose to investigate the characteristics of 3 extremely large volume (>1,000 km3) pyroclastic flow deposits in the Andes of South America, to understand the eruption origins and the flow dynamics of such large volume and potentially far flowing (up to 200 km from the vent) pyroclastic flows. These are potentially more destructive than the Indian Ocean tsunami event, and eruptions of this magnitude could occur in Indonesia, PNG and New Zealand.Read moreRead less
Neotectonics of the Indo-Australian plate. This project will contribute fundamental insights into the dynamics of our planet, towards earthquake risk assessment and to evolution of Australia's distinctive landscapes. The benefit of this project can therefore be evaluated in light of its contribution to the social and economic repercussions of improved understanding of earthquake risk and our landscapes and our place in them.
The propagation of gravity currents over complex terrain. Dust storms, volcanic eruptions, rivers rushing sediment into lakes and seas, and spillages of toxic liquids and gases, are all examples of environmental problems that can occur, and when they do, they threaten both wild life and human communities. This project involves research that will provide quantitative understanding of key processes in these problems from which reliable software will be built to predict their consequences. The soft ....The propagation of gravity currents over complex terrain.

This project involves research that will provide quantitative understanding of key processes in these problems from which reliable software will be built to predict their consequences. The software will produce an animation of dust containing fluids moving over a landscape of arbitrary complexity.Read moreRead less
Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes o ....Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes of significant cooling and denudation (i.e. low-level instability) which are invisible to other analytical techniques. The outcomes will open a new research avenue in these terrains, which host some of the world's most valuable mineral resources, underlie important petroleum basins and are potential long-term repositories for radioactive waste.

Argon thermochronometers and the effects of recrystallization. Rocks exhumed from high temperatures in continental settings contain a record of cooling in potassium-bearing minerals, known as thermochronometers, due to the quantitative retention of radiogenic argon below some characteristic closure temperature. However, thermochronometers may be affected by recrystallization processes occurring below such temperatures, and in some cases argon data record the timing of crystallization rather tha ....Argon thermochronometers and the effects of recrystallization. Rocks exhumed from high temperatures in continental settings contain a record of cooling in potassium-bearing minerals, known as thermochronometers, due to the quantitative retention of radiogenic argon below some characteristic closure temperature. However, thermochronometers may be affected by recrystallization processes occurring below such temperatures, and in some cases argon data record the timing of crystallization rather than cooling. Field, microstructural and isotopic analysis will be used to evaluate the effects of recrystallization on the muscovite and potassium-feldspar thermochronometers, particularly in fault zones. Understanding the effects of recrystallization on thermochronometers is critical for studies of the assembly of the continental crust.Read moreRead less
From crystal to craton: unravelling the low-temperature thermal evolution and long-term stability of cratonic lithosphere. The project will expand Australia's knowledge base by increasing fundamental scientific knowledge about the evolution of cratons, the old nuclei of the continents. These areas are important for the resources they contain and their potential elsewhere as stable sites for long-term nuclear waste repositories.

The project will expand Australia's knowledge base by increasing fundamental scientific knowledge about the evolution of cratons, the old nuclei of the continents. These areas are important for the resources they contain and their potential elsewhere as stable sites for long-term nuclear waste repositories. The project will also enhance our research capability by developing new methods and help to build and sustain world leading research capability in Australia. In addition, the project will forge strong international links with researchers overseas. Whilst not focussed directly on the National Research Priorities the project will nonetheless provide important background information to 'deep-earth resources' and 'geoinformatics'.Read moreRead less
