Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase ....Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase exploration efficiency, saving tens of millions of dollars currently devoted to unproductive exploration. Exploration and mining are conducted primarily in regional Australia, and a healthy mining industry is therefore directly benefits hinterland communities. It also benefits all Australians through the payment of royalties and contributions to Australia's GDP from mineral exports.Read moreRead less
Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine ....Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.Read moreRead less
Unmixing in Magmas: Melt and Fluid Inclusion Constraints on Identity, Timing, and Evolution of Immiscible Fluids, Salt and Sulphide Melts. Much of the research proposed herein genuinely breaks new ground in both the fields of igneous petrology and ore deposit geology. It will contribute to Australia maintaining a leading role (as identified in "Towards 2005 - a prospectus for research and training in the Australian Earth sciences") in the burgeoning field of melt inclusion research, and serve as ....Unmixing in Magmas: Melt and Fluid Inclusion Constraints on Identity, Timing, and Evolution of Immiscible Fluids, Salt and Sulphide Melts. Much of the research proposed herein genuinely breaks new ground in both the fields of igneous petrology and ore deposit geology. It will contribute to Australia maintaining a leading role (as identified in "Towards 2005 - a prospectus for research and training in the Australian Earth sciences") in the burgeoning field of melt inclusion research, and serve as a training base for young researchers keen to learn the techniques and methodologies involved. The possible outcomes of the project are of wide interest to geoscientists, and may benefit the Australian economy in that they help to predict whether the magmas have experienced exsolution of a metal-rich fluid.Read moreRead less
A melt inclusions pursuit into the identity of carbonatite magmas and their economic potential. The project will focus on close connections between mantle carbonate-rich magmas and the accumulation of rare metals and diamonds in the crust. This study is in an internationally competitive field, will educate young geoscientists in the use of modern research methods and will benefit the Australian communities and economy.
