Developing a geomorphological framework to underpin management decision-making on the Great Barrier Reef. The paucity of data on coral reef growth histories inhibits attempts to integrate regional reef growth data into coral reef management - despite the major influence on habitat type and diversity. This project will gather such data for one region of the Great Barrier Reef, and develop such datasets to support future reef management decision-making.
Exposure dating with manganese-53, neon-21 and beryllium-10: a new toolkit for studying long-term landscape evolution. Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known.

Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

Developing a fully automated analytical system for the next generation of fission-track thermochronology. This project aims to develop a revolutionary new generation of research tools for analysing the temperature history of rocks in the upper several kilometres of the earth's crust with new opportunities for the commercialisation of the outcomes. The approach will bring together and integrate several rapidly-developing technologies at the forefront of international developments in this field. ....Developing a fully automated analytical system for the next generation of fission-track thermochronology. This project aims to develop a revolutionary new generation of research tools for analysing the temperature history of rocks in the upper several kilometres of the earth's crust with new opportunities for the commercialisation of the outcomes. The approach will bring together and integrate several rapidly-developing technologies at the forefront of international developments in this field. The information obtained will contain vital clues about the processes that operate within the crust, the evolution of its surface environments over long periods of time, the long-term stability of the ancient continental cores, and the formation of important hydrocarbon and mineral resources.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

A Mission to Very Early Earth: When Did Conditions Suitable for Life Emerge on Earth? A uniquely Australian resource - 4.4-4.1 Ga detrital zircons from the Jack Hills (WA) - represent the only tangible record of the Hadean Eon (4.5-4.0 Ga) and potentially contain information regarding the origin of the atmosphere, hydrosphere, continental lithosphere, geodynamo, and perhaps even life, during the earliest stages of Earth evolution. Following age characterization of 100,000 zircons, experiments in ....A Mission to Very Early Earth: When Did Conditions Suitable for Life Emerge on Earth? A uniquely Australian resource - 4.4-4.1 Ga detrital zircons from the Jack Hills (WA) - represent the only tangible record of the Hadean Eon (4.5-4.0 Ga) and potentially contain information regarding the origin of the atmosphere, hydrosphere, continental lithosphere, geodynamo, and perhaps even life, during the earliest stages of Earth evolution. Following age characterization of 100,000 zircons, experiments involving short-lived nuclear chronometers and tracers of continental evolution (Hf and O isotopes) will be undertaken on the most ancient zircons that could both radically our paradigm for early planetary evolution and permit assessment of whether life emerged during the Hadean Eon.Read moreRead less
Time frame for the evolution of Australia's extraordinary mammals. This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity.

This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework will also serve evolutionary genetics which needs age data to calculate molecular rates of divergence, economic geologists needing to know the age of Cainozoic sediments, biologists trying to understand the origins and nature of biodiversity and conservationists using divergence dates and relative branch lengths to help determine conservation priorities.

Constraining landform response to tectonic and climate changes in an active orogen: a multi-disciplinary approach. The aim of this project is to quantify the efficiency of coupling between tectonics, climate and erosion in an active mountain belt, the Southern Alps of New Zealand, by combining world-class expertise in a range of fields, including the collection and analysis of thermochronological data, the analysis of digital elevation maps, morphometric field measurements, and the development a ....Constraining landform response to tectonic and climate changes in an active orogen: a multi-disciplinary approach. The aim of this project is to quantify the efficiency of coupling between tectonics, climate and erosion in an active mountain belt, the Southern Alps of New Zealand, by combining world-class expertise in a range of fields, including the collection and analysis of thermochronological data, the analysis of digital elevation maps, morphometric field measurements, and the development and use of numerical models, both tectonic and geomorphic. In particular, it is proposed to develop and use unique quantitative methods to interpret thermochronological data. This work will help resolve the current debate concerning the potential feedback between climate and tectonics.Read moreRead less

Uranium decay-series isotope studies are revolutionising this field by providing time information in the range 10^2-10^4 years, similar to that of many important Earth processes. This project will establish a world-class Australian Uranium-series research group to investigate the processes of magma formation and transport, continental growth, rates of erosion and recycling. These methodologies can also constrain processes governing water flow and reservoirs, mineral resources, volcanic eruptions, carbon cycles and other environmentally important processes/systems/cycles.Read moreRead less
