P. Jonathan Patchett
Professor, Geochemistry and Radiogenic Isotopes
My main research interests (though retired since 2011)
Evolution of the mantle-crust-hydrosphere of the Earth over geologic time reflected by geochemistry and isotopes. Specific broad projects from 1990 onwards: early crust-mantle evolution from Hf and Nd isotopes; origin of terrane components of orogenic belts; Nd isotopic and geochemical study of sedimentary provenance at continent scale; Sr isotopes and U-Th disequilibrium geochronology applied to Tertiary and Quaternary regional, environmental and climatic topics.
