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.

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

Understanding the Thomson Orogen, a geological region which straddles the New South Wales and Queensland border, is critical for developing geodynamic models for the evolution of eastern Australia, and assessing resource potential. However, it lies under the Great Artesian Basin. This project focusses on ground truthing geophysical acquisition studies using drill core from a targeted drilling program, designed to maximise the available tectono-stratigraphic information. The outcome intends to be a 3D geological map of the region, which can be interrogated for mineral exploration targeting, and from which 4D evolutionary geodynamic models of eastern Australian can be integrated.Read moreRead less

Summary
Access for Australian Researchers to Advanced Neutron Beam Techniques. Neutron scattering is one of the most powerful and important investigative tools in the study of materials. Australia has only a low-flux neutron source, HIFAR, which provides no cold or hot neutrons. This excludes large, important areas of science, such as functional films, polymers, self-assembly systems, biological materials, colloids and emulsions, and real-time in-situ studies.

This application aims to continue Australia's partnership with the world's most intense neutron source, ISIS in the UK, in order to sustain the considerable Australian scientific momentum which now relies on ISIS.
The outcomes will be new science that cannot be generated solely within Australia.

Summary
Access for Australian Researchers to Advanced Neutron Beam Techniques. The access to ISIS is of strategic benefit to Australia. In the 'run up' to the Replacement Research Reactor that benefit will be increased because of the current upgrade to ISIS and the imminent construction of a second target station to provide the world's best 'cold neutron' facilities.
