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
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
