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

Summary
Understanding the Earth: a perspective from the science of advanced materials. The study of the properties of naturally occurring minerals and magmas under extreme conditions of high temperature and pressure is needed, for understanding the geological processes responsible for our mineral wealth. The same methods can also lead to improved design of new materials required for technological applications.
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

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.

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.

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.

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
Understanding mineral reactivity using computer simulations at realistic pH. The results of fundamental environmental and technological processes such as the production of alumina and the management of mine wastes largely depend on careful controlling the conditions at which the chemical reactions occur.

The results of fundamental environmental and technological processes such as the production of alumina and the management of mine wastes largely depend on careful controlling the conditions at which the chemical reactions occur. Throughout this project, atomistic simulations will be used to unravel the effects of pH on the stability of minerals and to improve our knowledge of the dissolution and re-precipitation mechanisms of these materials. A better understanding of the basic science underpinning minerals’ reactivity will eventually translate into the development of new technologies and contribute to helping Australia’s advancement in developing a sustainable future as well as environment preservation and remediation.Read moreRead less

This project aims to increase our knowledge of the processes of mineral formation and crystallisation. Minerals play a vital role in our environment, for example as reservoirs for carbon dioxide, while also substantially contributing to the Australian economy. Conversely, undesirable formation of minerals can be detrimental to industries from the oil/gas sector through to desalination. Despite the benefits that would come from controlling such crystal growth, progress has been limited by the lack of a complete understanding of how minerals form at the microscopic level. This project aims to combine computer simulation, using the latest petascale resources, with experimental data to yield knowledge that would allow us to manipulate minerals, such as calcium carbonate, with the same control found in nature.Read moreRead less

This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas.

This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths this project aims to develop new reverse-engineering methods for their extraction, which will improve the security of supply of these elements and enhance Australia's role in high-tech industries. The project will enhance the profitability of the Australian resources sector through improved extraction economics and will secure the supply of these critical metals for Australian high-tech industries and export. The outcomes will be targeted initially at junior resource companies that are not yet profitable.Read moreRead less
