Summary

Working within ore deposit research I'm particularly enthused by minerals and complex natural systems. If not looking at rocks then I tend to be perusing other activities including landscape photography, woodwork and mining history. Research interests are in British geology, strike-slip tectonics, granite petrogenesis, pegmatites, and of course magmatic and hydrothermal ore forming processes - especially concerning Pb-Zn and Cu deposits. My PhD study is allied closely with the mining industry, aiming to improve our knowledge of metal dispersion in porphyry magmatic-hydrothermal ore systems. The work is focused on understanding the origin and characteristics of distal propylitic alteration and how this relates to major ore-forming events. Propylitic alteration, marked by the development of epidote, chlorite, albite and calcite is the most distal and pervasive facies associated with porphyry deposits. A thorough understanding is therefore essential to improving mineral exploration and learning how these hydrothermal systems interact with the country rock and existing fluids. The study is based around the Northparkes Cu-Au Mine in New South Wales, Australia. To date it has involved extensive fieldwork, sample characterisation, stable isotope studies and geochemical investigations using acquired whole rock and mineral chemistry data. In addition to research, I also assist with undergraduate teaching at Imperial College London.
