Thesis title: Micro-porosity formation in viscously deformed rocks (supervised by Jacques Précigout, Cécile Prigent, Laurent Arbaret, Laura Airaghi)

I study granitic rocks which have been deformed in a viscous manner – either in the Earth's crust, or in a deformation apparatus (e.g. the Griggs Apparatus). The aim of my PhD is to study the micro-porosity which is found in deformed quartz, and try to understand how these pores might have formed under the high pressures and temperatures of viscous deformation. Understanding more about micro-porosity in deformed rocks may give us a better insight into how fluids are moved through shear zones in the Earth's crust. The analysis techniques I use to study these rocks and the micro-porosity within them include microscopy (optical, SEM & TEM), Hyperspectral Cathodoluminescence and Electron Backscatter Diffraction (EBSD).
