This project aims to develop technologies to mitigate three dimensional (3D) geological risk in resources management. This project expects to create new knowledge and methods in the field of 3D geological modelling through the innovative application of mathematical methods, structural geology concepts and probabilistic programming. The expected outcomes are an enhanced capability to model the subsurface, characterise model uncertainty and test multiple geological scenarios. This enhanced capability is important for the future of Australia's subsurface management, including urban geology and our continuously growing sustainable resources industry.Read moreRead less

The project aims to develop technologies enabling rapid informed decision-making related to the management of natural resources, including critical metals, copper and water. This new technology will support a greener future, securing our energy future, our access to clean water and reduce the mining footprint. Expected outcomes include an enhanced capability in interoperable, integrated three-dimensional geological and geophysical modelling in order to predictively characterise sub-surface geology. The outcome will be an open-source forecasting dashboard enabling decision making while considering underlying risk related to resource extractions and management with significant benefits to the Australian society (lower emissions, clean water).Read moreRead less
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
The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? The hypothesis that all of Earth's continents came together one billion years ago to form a supercontinent known as Rodinia has invigorated debate about ancient continental distributions. Current models depict a flawed configuration for Rodinia, since they assume that continental fragments preserving evidence for quite different episodes of tectonic activity between ....The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? The hypothesis that all of Earth's continents came together one billion years ago to form a supercontinent known as Rodinia has invigorated debate about ancient continental distributions. Current models depict a flawed configuration for Rodinia, since they assume that continental fragments preserving evidence for quite different episodes of tectonic activity between 1350 and 900 million years ago developed at the same time. This project will make new correlations based upon careful observation and precise isotopic dating of rocks in Antarctica and Mexico, and will use these data to develop a more realistic picture of the ancient Earth.Read moreRead less

Summary
A new seismic facility for investigating tectonic collision zones, earthquake hazards and passive imaging techniques. A new seismic facility will enable collaboration with overseas partners to better understand plate margin tectonics and earthquake hazard in our region for mutual benefit. It will also be used in pilot studies of areas endowed with deep earth resources, and in assessing regions of heightened earthquake activity in Australia.
Geodynamic evolution of the Banda Arc. The project will contribute to a better understanding of plate tectonic processes and will provide insights into the dynamics of the Indo-Australian plate. This information is fundamentally important for estimating seismic hazards and the potential for generating large magnitude earthquakes in Australia. Outcomes of this project will facilitate to unravel analogue tectonic systems that were active during the geological evolution of Australia (e.g. the Lachl ....Geodynamic evolution of the Banda Arc. The project will contribute to a better understanding of plate tectonic processes and will provide insights into the dynamics of the Indo-Australian plate. This information is fundamentally important for estimating seismic hazards and the potential for generating large magnitude earthquakes in Australia. Outcomes of this project will facilitate to unravel analogue tectonic systems that were active during the geological evolution of Australia (e.g. the Lachlan fold belt in eastern Australia), thus providing a new insight into the Australian environment. The project will also elucidate the nature of tectonic processes that are known to generate major ore deposits and is therefore likely to have important economic implications.Read moreRead less
The early tectonic evolution of the Curnamona Province. This project aims to test the hypothesis that the Curnamona Province preserves evidence for an extension-related structural geology architecture. This will allow a comparison of the basin evolution, crustal architecture and mechanisms of basin development between the Curnamona Province and well-understood basins of the Mount Isa Inlier. The project is expected to add value to pre-existing databases, and deliver a plate tectonic and str ....The early tectonic evolution of the Curnamona Province. This project aims to test the hypothesis that the Curnamona Province preserves evidence for an extension-related structural geology architecture. This will allow a comparison of the basin evolution, crustal architecture and mechanisms of basin development between the Curnamona Province and well-understood basins of the Mount Isa Inlier. The project is expected to add value to pre-existing databases, and deliver a plate tectonic and structural framework to interpret basin evolution and constrain geochronology/geochemical analysis, and develop a three-dimesional crustal architecture. The results will provide new constraints on the evolution of the Australian plate, and how the Australian crust has evolved.Read moreRead less
The Golden Gift gold mineralisation, Stawell, Victoria. The structure and the nature of the fluid flow that produced the mineralisation in the newly discovered Golden Gift orebody at Stawell, Victoria, will be investigated. This project will provide reasons for the distribution of the gold lodes, the distribution of major quartz vein arrays and associated fractures.

The structure and the nature of the fluid flow that produced the mineralisation in the newly discovered Golden Gift orebody at Stawell, Victoria, will be investigated. This project will provide reasons for the distribution of the gold lodes, the distribution of major quartz vein arrays and associated fractures. Using both the existing and new geologic data and numerical models it should be possible to establish the primary setting for the Stawell goldfield. The models will be applicable not only to the Golden Gift orebody but will provide insights into the importance of these processes in controlling the localisation of gold mineralisation in other terranes.Read moreRead less

In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in gold deposit genesis.
