Integrating Stress and Strain Data from the North West Shelf, Australia: Implications for Hydrocarbon Seal Integrity. Many exploration wells in the Australian North West Shelf encounter residual columns from which hydrocarbons have leaked due to fault reactivation. Recently there has been a significant increase in our knowledge of contemporary stress (from data such as borehole breakouts)
and strain (from fault reactivation styles) on the North West Shelf.
This project will integrate informati ....Integrating Stress and Strain Data from the North West Shelf, Australia: Implications for Hydrocarbon Seal Integrity. Many exploration wells in the Australian North West Shelf encounter residual columns from which hydrocarbons have leaked due to fault reactivation. Recently there has been a significant increase in our knowledge of contemporary stress (from data such as borehole breakouts)
and strain (from fault reactivation styles) on the North West Shelf.
This project will integrate information on stress and strain in order to investigate whether the current state-of-stress is consistent with
observed reactivation styles, and thus develop predictive models for
fault reactivation and hydrocarbon leakage based on the distribution of
stress and strain.Read moreRead less
The neo- and seismo-tectonics of northwestern Australia. Australia's two largest earthquakes occurred in NW Australia (magnitudes 7 and 7.9 in 1941 and 1906). Onshore and offshore geologic evidence indicates other such events in recent geological history. Our present seismic database records no such events. We propose to document the nature, frequency, intensity, distribution and possible causes of seismicity in NW Australia, through deployment of seismograph arrays. We will test the effects ....The neo- and seismo-tectonics of northwestern Australia. Australia's two largest earthquakes occurred in NW Australia (magnitudes 7 and 7.9 in 1941 and 1906). Onshore and offshore geologic evidence indicates other such events in recent geological history. Our present seismic database records no such events. We propose to document the nature, frequency, intensity, distribution and possible causes of seismicity in NW Australia, through deployment of seismograph arrays. We will test the effects of basement reactivation, determine the crustal structure beneath the cratonic mass, examine onshore and offshore faults, determine local and regional stress orientations and investigate implications for petroleum production in the region, and whether natural resource extraction causes local seismicity.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
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
