Shear heating in granular materials: micromechanics of thermal conduction and production. Oil, gas and geothermal exploration are amongst the major energy industries in Australia and must be optimised to enable efficient production. These processes are dominated by the transfer of heat through granular soil media. Past research was based on continuum heat-flow solutions, but these problems are governed by distinct networks of particle-particle contacts and interparticle pore-fluids.

Oil, gas and geothermal exploration are amongst the major energy industries in Australia and must be optimised to enable efficient production. These processes are dominated by the transfer of heat through granular soil media. Past research was based on continuum heat-flow solutions, but these problems are governed by distinct networks of particle-particle contacts and interparticle pore-fluids. Heat-flow solutions depend on effective terms of thermal conduction, production and convection, but these change with loading. A systematic study must therefore be accomplished to formulate the micromechanics of the effective thermal properties, such that continuum solutions are refined to optimise energy exploration.Read moreRead less
Thick-skin continental deformation and the rheology of faulted continental lithosphere. We plan to study the way in which major, long-lived faults influence the large-scale deformation of continental lithosphere in response to plate and mantle derived stresses. We will develop realistic computer models of networks of faults embedded in the crust to examine the way large faults (e.g. the San Andreas fault in California) interact with the deep crust and shallow mantle and the way they interact w ....Thick-skin continental deformation and the rheology of faulted continental lithosphere. We plan to study the way in which major, long-lived faults influence the large-scale deformation of continental lithosphere in response to plate and mantle derived stresses. We will develop realistic computer models of networks of faults embedded in the crust to examine the way large faults (e.g. the San Andreas fault in California) interact with the deep crust and shallow mantle and the way they interact with each other. No one previous model has been able to incorporate all the important dynamics. The work will be used by structural geologists, planetary scientists and be a valuable tool in mineral exploration.Read moreRead less
