The impact of reactive fluids on fault mechanics near the seismic-aseismic transition in the continental crust and subduction zones. This project explores how fluids influence the strength and behaviour of earthquake-producing faults. The results will contribute to understanding processes controlling nucleation and recurrence of earthquakes on large faults near tectonic plate boundaries.

Summary
Tectonic drivers of extreme metamorphism in Eastern Indonesia. This project intends to investigate the tectonic drivers of (ultra-)high temperature metamorphism in eastern Indonesia. Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved.

Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved. Eastern Indonesia is one of the few places where active subduction can be linked directly to recent mountain building. Better understanding of how complex subduction dynamics and how mountain belts form is intended to assist natural hazard assessment in earthquake-prone areas.Read moreRead less
Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine ....Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.Read moreRead less
