Emeritus Professor Bruce Yardley

Prof. Bruce Yardley's research interests are in fluid processes in the Earth's crust, and span a wide range of topics, including aspects of ore formation, diagenesis and prograde and retrograde metamorphism, taking place at all levels in the crust. He is particularly interested in chemical mass transfer by fluids and in the cycle of interactions between fluid flow, temperature, mineralogical reactions and the rheology and permeability of the crust. The techniques that his group has employed in recent years include field and petrographic observations, rock and mineral analysis, fluid inclusion studies (including multi-element chemical analysis), experimental studies and geochemical modelling of fluid rock interaction. He is interested both in exploiting results from the study of active processes today for the improved understanding of ancient flow regimes, and in understanding how human activity in the subsurface may modify natural processes in the future.
