Summary
Tectonic drivers of extreme metamorphism in Eastern Indonesia. This project intends to investigate the tectonic drivers of (ultra-)high temperature metamorphism in eastern Indonesia. Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved. Eastern ....Tectonic drivers of extreme metamorphism in Eastern Indonesia. This project intends to investigate the tectonic drivers of (ultra-)high temperature metamorphism in eastern Indonesia. Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved. Eastern Indonesia is one of the few places where active subduction can be linked directly to recent mountain building. Better understanding of how complex subduction dynamics and how mountain belts form is intended to assist natural hazard assessment in earthquake-prone areas.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

Summary
Characteristics and controls of ice sheet loss on centennial timescales. This project aims to unearth the characteristics and controls of Antarctic ice sheet loss on timescales of 100s to 1000s of years. The polar ice sheets are getting smaller at an accelerating rate in response to a warming climate, but modern observations are not yet sufficient to determine whether current ice sheet loss marks the start of irreversible retreat. Through a combination of novel geological approaches and numerica ....Characteristics and controls of ice sheet loss on centennial timescales. This project aims to unearth the characteristics and controls of Antarctic ice sheet loss on timescales of 100s to 1000s of years. The polar ice sheets are getting smaller at an accelerating rate in response to a warming climate, but modern observations are not yet sufficient to determine whether current ice sheet loss marks the start of irreversible retreat. Through a combination of novel geological approaches and numerical ice-flow modelling, this project expects to generate new knowledge on the rates and magnitudes of ice sheet loss, and the processes that will dictate the amount of ice loss in this century and beyond. This work should be beneficial for managing the societal, economic and environmental impacts of future sea-level rise.Read moreRead less

Summary
How does the continental crust get so hot? This project is aimed at constraining the tectonic drivers of high geothermal gradient crustal regimes. The key outcomes of this project are better constraints on the tectonic drivers of high geothermal gradient metamorphism and the development of quantitative tools to assess the evolution of heat within areas of mountain building.

Summary
Are northern- and southern-hemisphere climates synchronised on orbital timescales? New insight into Earth's climate history. This project will generate a very high (1-100 year) resolution palaeoclimate record in order to test whether southern hemisphere ice age climate changes 1.5 million years ago were synchronised with the northern hemisphere. This will provide a critical test of theories on the mechanisms driving glacial- interglacial climate changes.

Summary
Old stalagmites, new techniques: South African palaeoclimate records linked to early human evolution. Caves in South Africa preserve a rich hominin (early human) fossil and archaeological record dating back over two million years. This project uses stalagmites from various South African caves to provide a new, detailed record of the palaeoclimate, forming the backdrop to the evolutionary changes that took place during this period.
