Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channel ....Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channels of chemical data for each grain in the 10,000s of analyses, there are 7 layers of lab imaging data that are not carried along in a convenient way. Geologists need smart computer systems to find useful relationships among the 33 channels and to discover relations within and between samples to find more mineable copper. Read moreRead less

The project will provide a new set of tools to explore for gold-rich ore deposits in Australia and globally. By integrating geochemical studies with cutting-edge experiments carried out at three Australian universities in strategic partnership with industry, the outcomes of this project will provide much needed knowledge to predict the locations of large gold-rich deposits that are concealed beneath vast expanses of the Australian continent. The new results will translate into smarter exploration practice, significantly enhancing success in targeting ore deposits that are rich in high-value metal and display the smallest have a small environmental footprint, to underpin the sustainability of our nation into the future.

This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.Read moreRead less

The pulse of the earth. The pulse of the earth. This project aims to establish the origin and evolution of the continental crust and its role in the long term development of the Earth system. The continental crust hosts the resources on which we depend and its evolution controls the environment in which we live. The crust’s record (including resources) is episodic in space and time, but the origin of this periodicity is unresolved.

This project aims to establish the origin and evolution of the continental crust and its role in the long term development of the Earth system. The continental crust hosts the resources on which we depend and its evolution controls the environment in which we live. The crust’s record (including resources) is episodic in space and time, but the origin of this periodicity is unresolved. Building on recent advances on crustal development, the fellowship would work to resolve the origin of the episodic age pattern, which affects the distribution of mineral systems and their prospectivity.Read moreRead less

This project aims to measure the high-temperature geochemical properties of the precious metals, which include gold, silver and the platinum group elements. The measurements are needed to quantify the partitioning of the precious metals between silicate melts and metal or sulfide, which would enable their distinctive geochemical properties to be applied to the testing of current hypotheses on how Earth formed, the composition of Earth's mantle through time, the relationship of Earth to the Moon, and the evolution of magmatic systems to form copper-gold deposits. The measurements have become feasible due to newly developed experimental and analytical methods, which avoid the problems that have bedevilled previous attempts.Read moreRead less
