Pressure waves on the mechanics of earthquakes and faulting. This project aims to decipher the physics of faulting and earthquakes from damage zones around seismogenic faults. It will examine a mechanism for instability in solids: volumetric collapse due to a dissipative pressure wave. This pressure wave may control damage-zone geometry and relate to earthquake stress and rock material properties. The project will research the instability through theoretical, laboratory and field studies. Antici ....Pressure waves on the mechanics of earthquakes and faulting.

This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work. The project expects to provide a well-dated sequence for Kimberley rock art based on replication of results, confirmation across different methods, and a large interdisciplinary data set. The project will allow rigorous analysis of the relationship between dating results and rock art styles that has not previously been possible, and give new insights into Australia’s deep indigenous heritage. This will have a significant impact for future efforts in rock art conservation, and lay a foundation for cultural tourism, with important benefits for the local economy and health of regional indigenous communities.Read moreRead less

Summary
A new nano-geochronology approach to global Earth processes. This project aims to develop a new nano-geochronology tool. Geochronology is the science of determining the ages of rocks and geological events, and is key to answering fundamental questions of planetary evolution, the geological processes that shaped our Earth, and evolution of life and past climates. Many valuable mineral phases are too small to be dated by conventional methods. The potential that nano-geochronology has to unlock inf ....A new nano-geochronology approach to global Earth processes. This project aims to develop a new nano-geochronology tool. Geochronology is the science of determining the ages of rocks and geological events, and is key to answering fundamental questions of planetary evolution, the geological processes that shaped our Earth, and evolution of life and past climates. Many valuable mineral phases are too small to be dated by conventional methods. The potential that nano-geochronology has to unlock information otherwise untraceable remains largely unexplored. The development and application of nano-geochronology will improve our understanding of the Australian crust and the field of geological mapping, which largely supports mineral exploration.Read moreRead less
Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large ....Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large-strain theory tailored to rocks experimentally, and to apply it to a pivotal geological problem: shear zone formation. The project will advance our fundamental understanding of the mechanics and energetics of rock deformation and provide a novel tool for the modelling of large deformations.Read moreRead less

Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integ ....Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integrating multi-method thermochronological and structural data on major Meso-Cenozoic Central Asian fault systems. The resulting time-integrated tectonic model will aid in the understanding of the India-Eurasia collision, the building of the mountainous Central Asian landscape and its influence on the Asian climate.Read moreRead less
