The structure and geochemistry of mineral interfaces in Earth's mantle. The interfaces between mineral grains are critical in determining rock properties and behaviour, yet we know little about them. This project uses emerging nano-technologies to establish the structure, chemistry and energy characteristics of interfaces in rocks from Earth’s mantle that control fundamental Earth processes such as plate tectonics and melting.

The interfaces between mineral grains are critical in determining rock properties and behaviour, yet we know little about them. This project uses emerging nano-technologies to establish the structure, chemistry and energy characteristics of interfaces in rocks from Earth’s mantle that control fundamental Earth processes such as plate tectonics and melting. The expected outcomes include a new understanding on one of the fundamental controls on rock properties and an enhanced ability to predict and model rock behaviour. The project provides research training in innovative research methodologies, will strengthen Australia’s leadership in nano-geoscience and will provide new methodologies for advanced rock characterisation.Read moreRead less
The Effects of Crystal-Plastic Deformation on Zircon Geochemical Systems. This project establishes the significance of deformation-related fast-diffusion pathways on the zircon geochemical system and develops intragrain compositional variations as new tools for tracking geological processes. The unique application of zircon to constrain geological processes in numerous Earth Science disciplines over 4.4 billion years of Earth history ensures that results will have far-reaching impact in the Aust ....The Effects of Crystal-Plastic Deformation on Zircon Geochemical Systems. This project establishes the significance of deformation-related fast-diffusion pathways on the zircon geochemical system and develops intragrain compositional variations as new tools for tracking geological processes. The unique application of zircon to constrain geological processes in numerous Earth Science disciplines over 4.4 billion years of Earth history ensures that results will have far-reaching impact in the Australian and International Earth Science community. As such this project will maintain Australia's leading international reputation in accessory mineral research.Read moreRead less

Australian Research Council
Funding Amount
$155,000.00
Summary
The first Australian high pressure Synchrotron facility for geoscience research. In high-pressure mineral physics and chemistry, mineral properties, stress-strain relationships and processes like partial melting are applied to geophysical research about the deep Earth. This project will provide a large volume, high pressure capability at the Australian Synchrotron which will allow these mineral properties to be measured under conditions which simulate the deep earth.

Summary
Solving the mystery of natural carbon mineralisation in Australian lakes. Some lakes, such as the Coorong lakes in South Australia, naturally sequester carbon dioxide in magnesium carbonate minerals. These minerals, which form in association with microorganisms in lake water, represent the safest possible long-term traps for carbon dioxide pollution. This project aims to determine the essential geochemical constraints on formation of magnesium carbonate minerals in the Coorong lakes, which are u ....Solving the mystery of natural carbon mineralisation in Australian lakes. Some lakes, such as the Coorong lakes in South Australia, naturally sequester carbon dioxide in magnesium carbonate minerals. These minerals, which form in association with microorganisms in lake water, represent the safest possible long-term traps for carbon dioxide pollution. This project aims to determine the essential geochemical constraints on formation of magnesium carbonate minerals in the Coorong lakes, which are unique natural laboratories for studying carbon dioxide sequestration. By delivering fundamental understanding of how microbial populations alter water chemistry for carbonate production, this project aims to inform the design of efficient and sustainable technologies for carbon dioxide sequestration that emulate natural processes in lakes.Read moreRead less
Microbially induced calcium carbonate precipitation in different substrates. Carbonates in the form of limestone represent an important reservoir of carbon on earth. They are recorded in several natural geological formations as corals, stromatolites, beach rocks. Microbes play an important role in the formation as well as dissolution of carbonates during microbially induced calcium carbonate precipitation (MICP) reactions on different substrates in natural and built environments. Much of our kno ....Microbially induced calcium carbonate precipitation in different substrates. Carbonates in the form of limestone represent an important reservoir of carbon on earth. They are recorded in several natural geological formations as corals, stromatolites, beach rocks. Microbes play an important role in the formation as well as dissolution of carbonates during microbially induced calcium carbonate precipitation (MICP) reactions on different substrates in natural and built environments. Much of our knowledge on MICP is limited due to poor understanding of the reaction kinetics at a molecular level. This project will develop new methods to enable and advance the knowledge of MICP process with profound implications for understanding natural geological formations as well as widen the scope of current engineering applications.Read moreRead less
