Earth, interstellar and extreme environments

Oral

Geochemical variation in the Earth, such as the chemical differences between the core, mantle and crust, are fundamentally explained through understanding of how elements
are partitioned amongst metals, minerals and melts over a wide range of pressures, temperatures, and redox conditions. The dominant framework for considering trace element behaviour in mineral/silicate-melt systems is the...

Oral

Coal seams are characterised as fractured reservoirs, consisting of natural fractures/cleats running through the coal matrix. The porosity and permeability of fractured coal are highly stress-sensitive. A bundled matchstick model is widely used to describe the cleat system. Based on this model, the well-known cubic law can describe the permeability change in response to fracture...
