Investigating mineral alteration and infilling of discontinuities in naturally deformed rocks as a guide to rock mass rheology. Structural analysis of naturally deformed rock will be used to investigate the origin, physical characteristics and frictional behaviour of naturally formed discontinuity surfaces. Discontinuities in naturally deformed rock masses are typically altered and infilled with complex combinations of mineral matter and are a major control on the rheology, including strength a ....Investigating mineral alteration and infilling of discontinuities in naturally deformed rocks as a guide to rock mass rheology. Structural analysis of naturally deformed rock will be used to investigate the origin, physical characteristics and frictional behaviour of naturally formed discontinuity surfaces. Discontinuities in naturally deformed rock masses are typically altered and infilled with complex combinations of mineral matter and are a major control on the rheology, including strength and stability, of rock masses in engineering excavations. By combining structural geology techniques and laboratory experiments, and with reference to existing data on field-scale rock mass deformation derived from engineering rock mechanics investigations, a methodology for predicting rock mass rheology from fundamental geological observations will be devised and tested.Read moreRead less
Enhanced Analysis and Structural Design of Pavements - Virtual Laboratory for Advanced Pavement Design. The proposed research will lead to improved pavement engineering procedures, which will reduce the maintenance costs for future pavement projects, and will result in cost-effective and more reliable design of new pavements.
Murray Basin: A unique archive of late Neogene global change. Salinization, soil erosion, groundwater depletion and surface water degradation are but a few of the inter-related environmental problems facing the Murray-Darling Basin. These problems require an understanding of the way in which shallow groundwater, salts and surface water interact with near-surface sediments. This project is aimed at a better understanding the nature of those near-surface sediments in the Murray Basin and how th ....Murray Basin: A unique archive of late Neogene global change. Salinization, soil erosion, groundwater depletion and surface water degradation are but a few of the inter-related environmental problems facing the Murray-Darling Basin. These problems require an understanding of the way in which shallow groundwater, salts and surface water interact with near-surface sediments. This project is aimed at a better understanding the nature of those near-surface sediments in the Murray Basin and how they were formed. If we can understand how the basin came to be the way it is (in the modern setting), we may better understand the way it might behave when subject to man-made changes like increased groundwater usage, etc.Read moreRead less
Microscale evolution of deformed rocks and glaciers. Scientific outcomes from this research have significant implications for predictions on material properties and are applicable to rock behaviour in mineralised systems, a focus of Australia's minerals industry, and the development of new materials for the Australian manufacturing industries. It will help maintain Australia's excellent international research reputation in the fields of microstructural geology and glaciology.
Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the ....Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the northern and southern Australian cratons. By constraining models of crustal evolution and architecture, the project will underpin future mineral exploration programs in this highly prospective greenfields region and define the role of the Musgrave Block in the assembly of Proterozoic Australia.Read moreRead less
Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and ....Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and geophysical tools to develop a comprehensive model for the tectonic evolution of the Gawler Craton. The project will constrain the development of the Gawler Craton in the context of Precambrian Australian evolution, and offer insights into universal processes of lithosphere formation, growth and stabilisation.Read moreRead less
Microstructural analysis using integrated experiments and numerical modelling. Microstructures related to nano-materials and visible up to the scale of a thin section, are important tools for any material scientist, geologist or glaciologist. Microstructural evolution underpins how these disciplines unravel grain-scale structures, deformation conditions and mechanisms to estimate the intensity or amount of deformation. This project will allow us to better interpret microstructural evolution, in ....Microstructural analysis using integrated experiments and numerical modelling. Microstructures related to nano-materials and visible up to the scale of a thin section, are important tools for any material scientist, geologist or glaciologist. Microstructural evolution underpins how these disciplines unravel grain-scale structures, deformation conditions and mechanisms to estimate the intensity or amount of deformation. This project will allow us to better interpret microstructural evolution, in a range of natural, organic and composite materials, by using integrated laboratory experiments and numerical simulations. With these results we will model the conditions that prevail in composite materials, in glaciers and apply them to processes operating in of the Earth's crust.Read moreRead less

The major aim of this collaborative study between Partner Oil Companies and The University of Melbourne is to understand seismic velocity problems associated with tropical carbonate sediments on Australias? North West Shelf. These problems can hinder the hydrocarbon exploration efforts below these carbonates. The project is a multi faceted study and will involve integration of seismic stratigraphy with sedimentological, micropaleontological, and geophysical data. The methods outlined below would underpin any seismic depth migration applications, thereby assisting with the delineation of new gas and oil fields, and help with the estimation of reserves in existing fields.

Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and th ....Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and the way in which these distributions have evolved during various tectonic processes, to elucidate the nature and significance of "tectonic feedback" and its role in shaping the continents.Read moreRead less
The Initiation and 3D Evolution of Instabilities in the Deep Continental Lithosphere. This project is part of a new international initiative in the Geodynamics of the Australian Plate bringing together studies of the active tectonics of the boundary regions of our plate and the ancient analogues of these processes which are locked into the stable interior of the Australian continent. The proposed research is a good fit to the Identification and Extraction of Deep Earth Resources priority goal.

This project is part of a new international initiative in the Geodynamics of the Australian Plate bringing together studies of the active tectonics of the boundary regions of our plate and the ancient analogues of these processes which are locked into the stable interior of the Australian continent. The proposed research is a good fit to the Identification and Extraction of Deep Earth Resources priority goal. Detachment of the lithosphere is associated with fertile mantle being emplaced at shallow depth below the crust; an important precursory event for mineralization. The project builds upon AuScope (NCRIS 5.13) to create infrastructure for a new, smart resource exploration and extraction industry based on modelling and simulation.Read moreRead less
