Numerical modelling of coupled deformation, fluid flow and heat flow in modern and ancient rifts

Computer modeling of geological processes is increasingly important to mineral and hydrocarbon exploration, to hazard prediction (e.g. earthquakes) and to plate tectonics. Because it is difficult to understand geological processes from ancient rocks, we will use new computer models to study fluid circulation in an active volcanic fault zone in New Zealand, where many of the parameters obscured in ancient rocks can be measured directly. We will determine processes of fluid migration that contributed to the formation of mineral deposits in ancient rocks, such as those mined in eastern Australia for gold. The project also has implications for discovery and development of energy resources including fossil fuels and geothermal waters.
