Biographical details

Geoffrey Clarke has been a Professor in the School of Geosciences since 2007.

Prof. Clarke was born in Melbourne and completed a B.Sc. (Hons) at the University of Melbourne between 1977 and 1980. From 1981 to 1983 he worked as a minerals exploration geologist for Esso Exploration and Production, in the Olary (South Australia), Cloncurry (Qld) and Charters Towers (Qld) districts. Clarke then retuned to the University of Melbourne to complete his PhD thesis between 1984 and 1987, working on structural and metamorphic relationships in granulite facies rocks of the Mawson Coast (Australian Antarctic Territory) and in the Olary and Broken Hill areas. In 1988, he assumed the post of research fellow at Macquarie University. From 1989 to 1990 Clarke was employed by the Regional Mapping section of the Geological Survey of Western Australia, preparing geological maps in the Rudall River area. In July 1990, he was appointed as a Lecturer in Geology at the University of Sydney.

Research interests

Prof. Clarke has contributed to all aspects of the textural analysis of high-grade metamorphic rocks. Field-based ARC-funded research on high-P Cretaceous granulites integrates tightly data from structural, petrologic and isotopic studies to study geological processes critical to the formation and modification of continental crust. Other ARC-funded research (with Powell, University of Melbourne) on the application of equilibrium thermodynamics has defined the P-T domains of common blueschist and eclogite facies assemblages, something that could not be done by direct experimentation, and established new approaches to the study of equilibrium during metamorphism. Clarke has also had ASAC-funded field programme examining lower crustal processes that formed high-grade rocks in MacRobertson and Kemp Lands, Australian Antarctic Territory. He is currently involved in a joint Australian-Indian research group reassessing processes responsible for forming rocks in the Himalayas.
