Global Lithospheric Architecture Mapping II. The continents have been rifted, or broken up, and collided, or re-assembled, along major zones of weakness many times throughout Earth's history. Boundaries between such continental domains focus large-scale movements of fluids that can produce giant ore deposits.

The continents have been rifted, or broken up, and collided, or re-assembled, along major zones of weakness many times throughout Earth's history. Boundaries between such continental domains focus large-scale movements of fluids that can produce giant ore deposits. This study will provide new perspectives on the localisation of world-class economic deposits, the Earth resources on which society depends. Innovations in imaging the deep Earth beneath continents, and in numerical modelling, will maintain our high international profile in research relevant to National Priority 1.6 (Developing Deep Earth Resources). Unique 3D geological maps of regions down to 250km will make the composition of deep Earth regions newly accessible to geoscientists and all potential endusers.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. D ....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. 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
Computer simulation to study emergence of material texture in the Earth and Plate Tectonics. Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to stu ....Computer simulation to study emergence of material texture in the Earth and Plate Tectonics. Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to study how the upper mantle emerges as a thermo-mechanically distinct boundary layer, how this emergent structure relates to anisotropy in the upper mantle, and how it is affected by cross-scale effects controlling fault zone behaviour and crustal dynamics.Read moreRead less
