Geoffrey Clarke

Professor Geoffrey L. Clarke is Professor Emeritus and Professor of Geosciences in the School of Geosciences, Faculty of Science, at the University of Sydney, where he has served since July 1990. He holds a PhD in Geology from the University of Melbourne and a B.Sc. (Honours) in Geology. Clarke has previously held the position of Head of the School of Geosciences and has taught geology courses, including coordinating Field Geology (GEOS3008) and supervising honours projects on topics such as meteorites. His career includes contributions to fieldwork in regions like central Australia and New Caledonia.

Clarke specializes in metamorphic petrology, granulites, eclogites, and geology. His research examines mineral equilibria, reaction textures, partial melting, and tectonic evolution through detailed petrological studies. Key publications include 'The interpretation of reaction textures in Fe-rich metapelitic granulites of the Musgrave Block, central Australia: Constraints from mineral equilibria calculations' (White, Powell & Clarke, 2002), 'Fractionation of bulk rock composition due to porphyroblast growth: effects on eclogite facies mineral equilibria, Pam Peninsula, New Caledonia' (Marmo, Clarke & Powell, 2002), 'Prograde metamorphic assemblage evolution during partial melting of metasedimentary rocks at low pressures: migmatites from Mt Stafford, Central Australia' (White, Powell & Clarke, 2003), 'Calculated mineral equilibria for eclogites in CaO-Na2O-FeO-MgO-Al2O3-SiO2-H2O: application to the Pouébo Terrane, Pam Peninsula, New Caledonia' (Carson, Powell & Clarke, 1999), 'Principles of Metamorphic Petrology' (Vernon & Clarke, 2008), 'Eocene arc-continent collision in New Caledonia and implications for regional southwest Pacific tectonic evolution' (Aitchison, Clarke, Meffre & Cluzel, 1995), 'A two-stage evolution of the Neoproterozoic Rayner Structural Episode' (Kelly, Clarke & Fanning, 2002), 'The lawsonite paradox: a comparison of field evidence and mineral equilibria modelling' (Clarke, Powell & Fitzherbert, 2006), 'Eclogites and blueschists of the Pam Peninsula, NE New Caledonia: a reappraisal' (Clarke, Aitchison & Cluzel, 1997), and 'The Late Jurassic to present evolution of the Andean margin: Drivers and the geological record' (Maloney, Clarke, Klepeis & Quevedo, 2013). Clarke has participated as Chief Investigator in Australian Research Council grants, including Discovery Project DP0342862, Strategic Research Pilot SR0566892, and Linkage Infrastructure LE130100099, advancing geoscientific instrumentation and analysis.
