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.

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
Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achiev ....Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achieve this goal, new methods for constructing multi-arrival wavefronts will be developed and applied to a range of seismic data from Tasmania to produce high resolution images of the crust and upper mantle.
