  • I- Subduction Theme

    Subduction zones represent sites of major chemical transfer between distinct external and internal reservoirs within Earth. Metamorphic rocks which typically develop in subduction settings and fingerprint those conditions are often overprinted by secondary processes, obscuring their primary histories and thus the secular geological record. Over the past 5 years, we sampled several famous HP-LT type localities to better understand the different chemical transfers occurring during subduction. This sample collection is currently used to develop new petrological tools and provides an independent means to assess subduction zones.

    II- Early Earth theme

    My current research focuses on exploiting chemical signatures locked within mineral phases to help understand large-scale Earth processes and geodynamics back in time. For this reason, in the past years I participated to  fieldwork expeditions which focussed on a detailed sampling of two Archean cratons (Kaapvaal, South Africa and Pilbara, Australia). These fieltrips were realised by developing strong collaborations with international specialists in geochemistry and Archean geology.

    Collaborators: Prof. Jean-Francois Moyen (University of Jean-Monnet, France), Prof. Peter Cawood and Oliver Nebel (Monash University, Australia) , Marc-Alban Millet (Cardiff University, Wales), Hugh Smithies (GSWA, Australia) and Dave Champion (Geosciences Australia).
