The Australasian Stress Map. The contemporary crustal stress field of Australasia is both more complex and more poorly constrained than that of other continental areas. The crustal stress field controls processes including earthquake hazard; the stability of mines, tunnels and boreholes, and; fluid flow in groundwater aquifers and oil reservoirs. Using data from oil exploration wells, earthquakes and recent geological activity, this project will increase from around 300 to 1000 the number of rel ....The Australasian Stress Map. The contemporary crustal stress field of Australasia is both more complex and more poorly constrained than that of other continental areas. The crustal stress field controls processes including earthquake hazard; the stability of mines, tunnels and boreholes, and; fluid flow in groundwater aquifers and oil reservoirs. Using data from oil exploration wells, earthquakes and recent geological activity, this project will increase from around 300 to 1000 the number of reliable stress determinations available for Australia, New Zealand and Papua New Guinea. The stress field will be modelled in order to improve our understanding of its origin and variability.Read moreRead less
Integrating Global Multidimensional Datasets to Underpin Subduction Process Modelling During the Past 60 Million Years. Subduction zones are the sites for massive sulphide, orogenic vein gold and porphyry deposits. As Australia derived 47% of it merchandise exports from its mineral and energy resources in 2001, ore-deposits constitute an important component of the Australian economy. Understanding the environment of subduction initiation and development as well as the signal that it imparts on ....Integrating Global Multidimensional Datasets to Underpin Subduction Process Modelling During the Past 60 Million Years. Subduction zones are the sites for massive sulphide, orogenic vein gold and porphyry deposits. As Australia derived 47% of it merchandise exports from its mineral and energy resources in 2001, ore-deposits constitute an important component of the Australian economy. Understanding the environment of subduction initiation and development as well as the signal that it imparts on the magmatic (ore-forming) arc, will provide improved efficiency for targeting Australia's deep-earth ore-deposits.Read moreRead less
