Minerals replacement reactions: understanding mineral formation under hydrothermal conditions. Many geological processes involve the transformation of one mineral into another. By understanding molecular-level reaction mechanisms, we can predict how fast reactions progress, and what the final product will look like. This project focuses on a reaction mechanism called 'coupled dissolution-reprecipitation', in which the parent mineral is dissolved into a thin layer of fluid at the reaction front, ....Minerals replacement reactions: understanding mineral formation under hydrothermal conditions. Many geological processes involve the transformation of one mineral into another. By understanding molecular-level reaction mechanisms, we can predict how fast reactions progress, and what the final product will look like. This project focuses on a reaction mechanism called 'coupled dissolution-reprecipitation', in which the parent mineral is dissolved into a thin layer of fluid at the reaction front, and the daughter mineral subsequently precipitates. This concept will be applied to sulfide minerals for the first time. The results have many applications for the Australian mining industry, in particular in improving the efficiency of the processing of Ni- and Au-ores.Read moreRead less
Contemporary sulfur biomineralisation in acid sulfate soil landscapes. This project aims to generate fundamental knowledge on the processes, kinetics and impacts to water quality of contemporary sulfur biomineralisation in acid sulfate soil landscapes. Extreme concentrations of highly reactive sulfides are forming in the surface sediments of floodplain drains, wetlands and agricultural soils. The newly forming sulfides are linked to severe oxygen depletion and acidification of coastal rivers a ....Contemporary sulfur biomineralisation in acid sulfate soil landscapes. This project aims to generate fundamental knowledge on the processes, kinetics and impacts to water quality of contemporary sulfur biomineralisation in acid sulfate soil landscapes. Extreme concentrations of highly reactive sulfides are forming in the surface sediments of floodplain drains, wetlands and agricultural soils. The newly forming sulfides are linked to severe oxygen depletion and acidification of coastal rivers and the complete failure of floodplain vegetation, leaving soils susceptible to erosion. The proposed study will greatly advance our understanding of how our precious coastal floodplain soil and water resources are being degraded, and will guide better land management.

Learning to predict polymorphism through simulation of nucleation and nanoparticle evolution. Many substances are capable of exhibiting a myriad of different structures despite having the same composition. This behaviour can have a significant impact on the production of new pharmaceuticals, since the sudden appearance of a new form can lead to instant withdrawal of the drug. By understanding how different forms grow, rather than focusing on just the stability of the product, this research will ....Learning to predict polymorphism through simulation of nucleation and nanoparticle evolution. Many substances are capable of exhibiting a myriad of different structures despite having the same composition. This behaviour can have a significant impact on the production of new pharmaceuticals, since the sudden appearance of a new form can lead to instant withdrawal of the drug. By understanding how different forms grow, rather than focusing on just the stability of the product, this research will lead to more reliable prediction of how pharmaceutical molecules might assemble. The same technology will potentially have impacts in many areas of nanoscience through improvements in efficiency, including the production of minerals, desalination and undersea gas recovery.Read moreRead less

Obtaining this information from small zones within single grains will allow determination of rates of change, and give us a detailed picture of how the host rock has evolved, even from very small samples. One application would be checking the origin of relatively common minerals for whether they could be associated with diamonds.Read moreRead less
Order-disorder behaviour in Bi-tellurides: a tool to monitor gold scavenging by Bi-Te melts. This project addresses a group of minerals (bismuth tellurides) that are often part of the exotic assemblages present in gold deposits, yet their potential to model the gold-forming processes is only recently apparent. These minerals also have the capacity to record their genetic history due to crystal modularity. Materials scientists target the analogous synthetic compounds because of the same structura ....Order-disorder behaviour in Bi-tellurides: a tool to monitor gold scavenging by Bi-Te melts. This project addresses a group of minerals (bismuth tellurides) that are often part of the exotic assemblages present in gold deposits, yet their potential to model the gold-forming processes is only recently apparent. These minerals also have the capacity to record their genetic history due to crystal modularity. Materials scientists target the analogous synthetic compounds because of the same structural modularity for applications in nanotechnology. The dataset on the mineral compounds, using the geological environment as a natural laboratory, will serve materials science research, as much as delivering key information relevant to understanding the reasons for gold enrichment in economically important types of ores.

Water storage in the earth's mantle - understanding the process of OH incorporation in olivine. The amount of water in the Earth's mantle is thought to be sufficient to replace the surface oceans more than ten times. Whether this water exists in a fluid, melt, or mineral is important for understanding a range of mantle properties. The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to thos ....Water storage in the earth's mantle - understanding the process of OH incorporation in olivine.

The entire upper mantle water budget may be accommodated at defect sites in the mineral olivine. However, defects found in natural olivine do not correspond to those produced
experimentally. Therefore, previous conclusions on water storage in the mantle are questionable. To address this problem the mechanism of water incorporation in olivine will be investigated using experimental petrology and spectroscopy.Read moreRead less
Experimental studies on hydrothermal reaction processes at the molecular level: the role of mineral replacement reactions in ore formation. Most of the World's supply of metals such as copper (Cu), gold (Au), molybdenum (Mo), lead (Pb), zinc (Zn) or uranium (U) comes from hydrothermal ore deposits. The metals were deposited deep below the Earth's surface when hot fluids, carrying minute quantities of the metals, reacted with suitable rocks to form ore minerals.

Most of the World's supply of metals such as copper (Cu), gold (Au), molybdenum (Mo), lead (Pb), zinc (Zn) or uranium (U) comes from hydrothermal ore deposits. The metals were deposited deep below the Earth's surface when hot fluids, carrying minute quantities of the metals, reacted with suitable rocks to form ore minerals. By understanding molecular-level reaction mechanisms at high pressure and temperature, we can predict the nature of the ore minerals formed for a given set of physical and chemical conditions. This multidisciplinary research project is devoted to understanding these chemical and physical processes and how this knowledge can be applied to improve mineral exploration, mining, and ore processing.Read moreRead less

The proposed project will extend this collaboration to develop a system for remote control of mDFP experiments, incorporating real-time data analysis and 3D visualization. This system will enable Australian scientists to use the Canadian mDFP, and subsequently the Australian Synchrotron mDFP, from their home institutions. The resulting flexibility of scheduling and alleviation of downtime for travel will be particularly beneficial for industry users.Read moreRead less
