Resolving the mystery of how rare earth elements are mobilised and concentrated in continental crust. Rare earth elements are regarded as the vitamins for modern industries and technologies. This project will investigate the geological processes that mobilise and concentrate these elements in the Earth's crust. The results will aid discovery of new ore deposits, which is essential to meet rapidly growing demand for these elements.
Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and frac ....Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.Read moreRead less

Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.Read moreRead less

A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years.

Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less

Australian research groups have been responsible for a number of leading technical developments in geological dating. This project will continue that track record and provide the core infrastructure to support a major collaborative research strength that can address both fundamental scientific questions about the evolution of the Earth's crust and surface environment, as well as important economic applications of that knowledge. These include the search for petroleum and mineral deposits, thereby addressing the National Priority Goal: Developing deep-earth resources. The project will strengthen links with other national and international researchers, and build Australia's research profile in an area of significant worldwide scientific interest.Read moreRead less

Application of the 40Ar/39Ar isotopic geochronometer to dating rocks, minerals, fossils and meteorites is limited by insufficient precision and consistency in existing determinations of the half-life of its parent isotope 40K.

Application of the 40Ar/39Ar isotopic geochronometer to dating rocks, minerals, fossils and meteorites is limited by insufficient precision and consistency in existing determinations of the half-life of its parent isotope 40K. This project proposes novel methods for determination of the half-life and branching ratio of 40K, by age comparison against well calibrated 87Rb-87Sr and 40K-40Ca geochronometers. The ages with all isotopic systems will be determined in the same minerals, thus eliminating the main source of uncertainty in the previous studies. Independently The project will measure the 40K decay rate by decay counting of highly enriched 40K salt and expects a five-fold improvement in precision and accuracy of known 40K decay rate.Read moreRead less
