It is important to improve the quality of their Talcom body powder, baby powder and other cosmetic products involving talc. The areas that can and need to be improved are shining characteristics, assessing the slip properties as well as developing the cosmetic chemistry of talc and other additives. The proposed project will generate: a) simple but reliable test methods for measuring slip and shine, b) methods for control of the physical and chemical characteristics of talc blends, c) mathematical model(s) for property and process control, which is useful to improvement of the final talc properties and in-use service.Read moreRead less

Deep earth cycles of carbon, water and nitrogen. This project aims to understand the roles of carbon, water and nitrogen in the development of plate tectonics as drivers of mantle evolution. Through improved understanding of the impact of melting on the deep earth cycles of carbon, water and nitrogen, this project intends to better understand how key elements are enriched towards economically viable concentrations. This project will generate knowledge of long-term benefit for decision-making in ....Deep earth cycles of carbon, water and nitrogen. This project aims to understand the roles of carbon, water and nitrogen in the development of plate tectonics as drivers of mantle evolution. Through improved understanding of the impact of melting on the deep earth cycles of carbon, water and nitrogen, this project intends to better understand how key elements are enriched towards economically viable concentrations. This project will generate knowledge of long-term benefit for decision-making in the minerals exploration industry and key government agencies. The project will establish a new generation of Australian scientists with a deep interdisciplinary understanding of earth sciences, and pave the way for eventual unification of plate tectonic with climate systems.Read moreRead less
Maximising accuracy and reliability of carbonate climate proxy archives. This project brings together expertise and cutting-edge methodology from different disciplines to identify the controls on the compositions of the shells and skeletons of marine organisms. The compositions of these materials are essential tools to reconstruct environmental conditions before modern climate records began. However, recent insights into how they form profoundly complicate and affect their interpretations.

This project brings together expertise and cutting-edge methodology from different disciplines to identify the controls on the compositions of the shells and skeletons of marine organisms. The compositions of these materials are essential tools to reconstruct environmental conditions before modern climate records began. However, recent insights into how they form profoundly complicate and affect their interpretations.
The results will enable us to develop new, realistic models for the behaviour of chemical elements in these materials. This will significantly improve paleoclimate interpretations and provide critical benefit for protecting Australia’s marine resources in the future. Read moreRead less
Rehydration of the lower crust, fluid sources and geophysical expression. This project aims to explore a long-standing mystery: the origin of deep crustal electrical conductors detected by magnetotelluric imaging of tectonically stable crust. These features occur in cratons of all ages, and commonly cross cut structures and lithologies. This project aims to investigate the hypothesis that such features are the record of ancient deep crustal fluid flow, which modified the rock electrical properti ....Rehydration of the lower crust, fluid sources and geophysical expression. This project aims to explore a long-standing mystery: the origin of deep crustal electrical conductors detected by magnetotelluric imaging of tectonically stable crust. These features occur in cratons of all ages, and commonly cross cut structures and lithologies. This project aims to investigate the hypothesis that such features are the record of ancient deep crustal fluid flow, which modified the rock electrical properties. Using an exceptionally exposed natural laboratory preserving large-scale rehydration of anhydrous lower crust, the project plans to determine the source of fluids and the compositional changes they induced. It then plans to experimentally determine changes in resistivity induced by fluid flow and use that data to model the magnetotelluric response at crustal scale.Read moreRead less
Earth's origin and evolution: a sulphurous approach. This project aims to shed new light on global element cycles in the deep Earth and how they connect to the evolution of the exospheres – one of the hottest topics in geosciences. It also aims to produce key knowledge of the extraction and transport of elements from the deep Earth to the surface, which may provide valuable information for resource exploration.

It also aims to produce key knowledge of the extraction and transport of elements from the deep Earth to the surface, which may provide valuable information for resource exploration. Using novel integrated elemental and isotopic approaches, this program aims to track the origin and fate of sulfur, selenium and tellurium during accretion and subsequent redistribution in fluids to Earth’s surface. This new knowledge is critical to understanding how these and other elements of strategic and economic importance, such as the Platinum Group Elements, are extracted from the deep Earth and transported to the surface.Read moreRead less

Australian virtual experimental laboratory: a multimode geoscience facility:
This project aims to establish seven types of high-pressure equipment to form a multi-node experimental laboratory at four locations across Australia. Experiments conducted at the high pressures and temperatures of the internal Earth form the basis of our knowledge about the physical and chemical processes that drive geological processes such as plate tectonics, melting to form volcanoes, and the formation and movement of fluids that concentrate precious metals into valuable ore deposits. The new facility may enable major advances in fields such as mantle geodynamics and element transport in fluids, improving our understanding of internal Earth processes and ore deposit formation and location. It also includes portable systems, which can be used in synchrotron applications.Read moreRead less

The aim of this project is to develop a geophysically relevant proton conduction model for the Earth’s upper mantle. This would allow the robust interpretation of conductivity maps of the interior of the Earth and the discovery of major new mineral deposits. This advance is designed to be achieved through four major initiatives based on recently developed experimental and computational facilities. The project aims to develop new methods for determining rock conductivities and subsurface mapping from combined datasets. This may provide new insights into the structure and dynamics of the upper mantle as well as providing key data necessary for a national effort aimed at re-establishing Australia as a primary target for mineral exploration.Read moreRead less

This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences indicates that these biocarbonates form via transient precursors rather than direct precipitation from seawater, profoundly affecting their interpretation. This project plans to transfer this new understanding to the earth sciences using nanoscale analytical methods including in vitro geochemical partitioning experiments. This would enable realistic models for geochemical proxy behaviour to be developed, significantly improving paleoclimate interpretations and assessments of ocean acidification effects on marine calcifiers.Read moreRead less
