Picture_1373 - Stephen Cox

Stephen Cox is professor of structural and economic geology in the Research School of Earth Sciences at the Australian National University.  His research interests are primarily in the coupling between deformation processes and fluid flow in crustal regimes, with applications to ore genesis and crustal mechanics.  His research is pursued via field-based studies, microstructural, microchemical and stable isotope analyses, high-pressure – high-temperature experimental studies, and some numerical modelling.  He holds a BSc (Hons) degree from the University of Tasmania and a PhD degree from Monash University.
Stephen is an external partner of the FRACs research consortium. He is currently based as a visiting scientist at RWTH-Aachen University for a half-year sabbatical.

Short course description and schedule:

Picture_1403 - WGGMAbstract: This course explores the coupling between deformation processes, permeability evolution and localization of fluid flow at depth in the Earth’s crust, with emphasis on fluid flow during crustal deformation.  The course links aspects of structural geology, rock mechanics, ore genesis and earthquake seismology to illustrate the dynamic competition between permeability-creation processes and permeability destruction processes in the continental seismogenic regime.  The course involves a series of lectures, interspersed with practical exercises and discussions over three days.  Examples will be drawn from experimental studies, analyses of ancient exhumed vein systems, fault zones and shear zones (both mineralized and unmineralised), as well as contemporary seismogenic systems.
