My research seeks to unravel the generation of the continental crust and the evolution of the crust-mantle system through a combination of detailed field study, trace element geochemistry and stable and radiogenic isotope tracing.
Specific aspects include:
- igneous processes and the origin of granitic and related rocks.
- petrological, geochemical and isotopic aspects of crustal melting.
- the processes and rates of continental crust generation and recycling through time.
- global links between felsic magmatism, crust generation and recycling through time.
- geochemical and isotopic evolution of Archean gneiss terranes and greenstone belts.
- crust-mantle exchange at subduction zones, subduction zone metamorphism.
- microchemistry and isotope geochemistry of accessory minerals by laser ablation and secondary ionization mass spectrometry.
- radiogenic and stable isotope geochemistry by multi-collector inductively-coupled plasma-source mass spectrometry.
