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
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 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. Anticipated outcomes include advances in earthquake and fault prediction, tools to determine the stress state and material properties of Earth’s crust, and knowledge of a class of solid instabilities.Read moreRead less
Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.

Summary
A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovation ....A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovations and technologies that underpinned the DFN, and leveraging a NASA partnership for administrative support and advanced instrumentation development. Tracking for space situational awareness is also expected to benefit Australian national security.Read moreRead less

SPIDE2R will be a new generation mass spectrometer for very precise and sensitive dating and forensics applications in earth and planetary sciences, hydrology, climate studies, and nuclear and archaeological fingerprinting. The unprecedented sensitivity of this unique instrument will provide enhanced capabilities for solving long-standing problems requiring precise geological time resolution, as well as opening new areas of research. It will be the instrument of choice for analysing small, rare samples such as those returned by space missions. The Australian-built high sensitivity source and ion detection systems can be retrofitted onto other mass spectrometers, opening a new area of commercialisation.Read moreRead less

This project links with major energy and resource initiatives from the Australian Government. It will provide detailed geological information that will help constrain our understanding of the deep structure of the Earth in northern and central Australia. This knowledge will assist in mineral and energy resource exploration of these highly prospective regions. The information will also link with other ARC-funded geological studies, to help understand how a large, but enigmatic, part of the Australian continental grew rapidly, almost 2 billion years ago.

The project directly addresses the key problem 'How do the continents work?', outlined by the National Committee of Earth Sciences. It links internationally to [ERAS], a multi-national proposal to investigate accretionary orogens through geologic time, and nationally via the seed-funded ARC Network (AEON) to ACcess, RSES (ANU) and with a National Key Centre, (GEMOC), with whom the University of Newcastle is a research partner. 2PhD projects are involved.Read moreRead less

Luminescence stimulation and detection facility for dating of Quaternary geological and archaeological sediments. Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits.

Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits. It exploits the radiation-induced thermally (TL) and optically stimulated luminescence (OSL) emissions from minerals exposed to sunlight before burial. Recent technical developments have made feasible OSL dating of small samples (e.g., individual sand grains) and sediments deposited during the past 0.5-1 million years. We request funds for a Risø TL/OSL system with single-grain attachment to resolve the timing of sea-level, climate and landscape changes, and the chronology of human evolution and dispersal, in Australia and Southeast Asia.Read moreRead less
