Research

I am interested in the development of small-scale and microstructures in large-scale shear zones, and their use as strain and vorticity gauges. Present funding from the Fonds de recherche du Québec – Nature et technologies (FQRNT) is for a project entitled: “Caractérisation pétrologique et datation radiométrique du métamorphisme régional est des failles dans la sous-province de l’Abitibi, Québec: implications tectoniques et métallogéniques,” in which I continue research on the timing of metamorphism and deformation in the Abitibi subprovince of Quebec. Specifically, I am investigating the formation and significance of shear band cleavages in a major shear zone in Val d'Or, Quebec, and to conduct Ar-Ar radiometric age dating on nearby fault rocks in order to better constrain the thermo-tectonic evolution of the area.
