Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish ....Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish accurate and precise structures for the oxides, and distinguish both long range and short-range order which is critical to understanding both natural and synthetic U-oxides. This will help to define the geochemical conditions leading to the formation of deposits like Olympic Dam towards potential economic benefit.Read moreRead less
Developing indicator minerals to geochemically fingerprint mineralized Fe oxide Cu-Au systems: a pilot study around the Ernest Henry Cu-Au mine. Fe oxide Cu-Au deposits represent some of the largest accumulations of economically extractable metal in the earth's crust. However, exploration has been largely ineffective over the last decade, and new methods for their delineation are required to deliver a step-change in the efficiency of exploration programs. The development of a mineral indicator s ....Developing indicator minerals to geochemically fingerprint mineralized Fe oxide Cu-Au systems: a pilot study around the Ernest Henry Cu-Au mine. Fe oxide Cu-Au deposits represent some of the largest accumulations of economically extractable metal in the earth's crust. However, exploration has been largely ineffective over the last decade, and new methods for their delineation are required to deliver a step-change in the efficiency of exploration programs. The development of a mineral indicator scheme to fingerprint potential ?ore-forming? systems using state-of-the-art laser ablation ICP-MS analysis may engender new methods and strategies that lead to exploration success. A baseline study around a known deposit provides the best means to characterize indicators- the Ernest Henry Cu-Au deposit provides the ideal candidate.Read moreRead less
A study of high temperature transformation of oil shale - In-situ mineral reactions and structure analysis. In the current energy market, non-traditional fuels like oil shale are becoming more economically important. Australia has >33 billion tonnes of oil shales resources with potential for >1800 million tonnes of recoverable oil. This potential multi-billion dollar industry depends upon development of an efficient technology leading to economical oil production and much cleaner organic liquid ....A study of high temperature transformation of oil shale - In-situ mineral reactions and structure analysis. In the current energy market, non-traditional fuels like oil shale are becoming more economically important. Australia has >33 billion tonnes of oil shales resources with potential for >1800 million tonnes of recoverable oil. This potential multi-billion dollar industry depends upon development of an efficient technology leading to economical oil production and much cleaner organic liquid fuels. Retorting and combustion, which are core parts of oil shale conversion technology, would benefit from improved process conditions. This research proposal intends to investigate the in-situ complex oil shale thermal conversion reactions that occur during the retorting and combustion processes. Improved understanding of these complex reactions could lead to substantial economic and environmental improvements in oil shale processing.Read moreRead less
