Dr. Anne-Aurélie Sappin
Research related to Ni-Cu-PGE, Cr, and Fe-Ti-V-(P) orthomagmatic deposits, rare metal deposits, and indicator minerals
Current research and/or projects
Research interests of Anne-Aurélie Sappin include the use of petrology, geochemistry, mineralogy, and geochronology to study volcanic and intrusive rocks hosting Ni-Cu-PGE, Cr, and Fe-Ti-V-(P) magmatic ore deposits, and rare metal mineralization. In particular, her works focus on the mechanisms responsible for the formation of these mineral deposits and on petrogenesis and geodynamic setting of their igneous host rocks. Anne-Aurélie Sappin is also interested in the study of indicator minerals (e.g., magnetite, ilmenite, chromite, and chalcopyrite) and their trace element contents and isotopic compositions, to determine the geochemical signatures characteristic of the different types of mineral deposits.
Anne-Aurélie Sappin has been part of the Targeted Geoscience Initiative (TGI4 and TGI5) and Geo-mapping for Energy and Minerals (GEM I and GEM II) government research programs. Currently, she is conducting research in the Bird River˗Uchi˗Oxford-Stull˗La Grande Rivière˗Eastmain superdomain (Superior Province), and in the Labrador Trough and Core Zone (Churchill Province).
