Simon Wilde applies fieldwork, petrology, geochemistry and geochronology to the study of crustal evolution. He mapped over 50,000 km2 of the southwest of Western Australia for the Geological Survey of Western Australia before moving to Curtin University, where he lectured in metamorphic and igneous geology. Current projects are in Antarctica Canada, China, Colombia, Cuba, Greenland, India, Iran, Iraq, Thailand, Vietnam and Western Australia. An overarching theme to this research is the desire to understand the range of processes that contribute to crustal evolution. Most of his work over the past decade has involved the application of U-Pb SIMS and Ar-Ar geochronology to key lithologies in the Yilgarn, North China and East Antarctic cratons and the Central Asian Orogenic Belt.
