Stéphane Perrouty
Biography
I completed a PhD at the University of Toulouse, France, a post-doctoral fellowship at the Institut de Recherche pour le Développement, France, and a post-doctoral fellowship at the University of Western Ontario, Canada. I'm currently involved in several multidisciplinary collaborative research programs, including the CFREF Metal Earth program, NSERC-CMIC Mineral Exploration Footprints program, and AMIRA's West African and South American Exploration Initiatives. My research integrates structural geology, mineralogy, lithogeochemistry, applied geophysics, and three-dimensional modelling to understand tectonic processes associated with Precambrian ore deposits.
Education
Post-Doctoral Fellow (2013-2017) - University of Western Ontario, Canada
Post-Doctoral Fellow (2012-2013) - Institut de Recherche pour le Développement, France
B.Sc. (2006), M.Sc. (2008), PhD (2012) - University of Toulouse, France
Research
My research aims to identify and understand tectono-stratigraphic factors and hydrothermal processes that lead to gold mineralization in Precambrian shields, in particular within Archean and Paleoproterozoic greenstones belts. I developed a broad research expertise integrating a range of disciplines in geosciences, with a primary interest in Precambrian geology, structural geology and modelling applied to gold exploration.

Teaching
GEOL 3006 - Field Geology II (Spring): This course introduces students to the fundamentals of field mapping. It is normally offered during the first two weeks of May. Students learn how to produce geological maps and cross-sections to document the 3D geological framework of four mapping areas, including 1) Huronian sandstones and Sudbury breccia in the Lake Laurentian Conservation Area, 2) poly-deformed gneisses in the Grenville Province (Crooked Lake), 3) the Grenville Tectonic Front, and 4) Huronian metasedimentary outliers on Archean basement (Bannerman Lake). Students develop general skills in orientation and map reading, use of airborne data, traverse and mapping techniques, field structural analysis, and technical report writing. PREREQ: GEOL 2126 (Mineralogy), GEOL 2237 (Rocks) and GEOL 3306 (Structural Geology).
GEOL 4016 - Precambrian Geology (Fall): This course introduces students to the evolution the Earth’s mantle, crust, surface, atmosphere and life from ~4568 Ma (formation of the Earth) to ~541 Ma (end of the Precambrian). It integrates multiple geosciences disciplines to solve Precambrian problems, including igneous petrography, structural geology, stratigraphy, sedimentology, geochemistry, stable and radiogenic isotope chemistry, geochronology, and geophysics. Precambrian rock types (e.g., Komatiites, TTGs, Iron Formations), geodynamic models (e.g., stagnant lid versus plate tectonic, crust formation and growth) and global changes (e.g., Great Oxidation Event, Snowball Earth) are discussed. The geology of several Precambrian regions around the world is presented, with a special emphasis on the Canadian Shield (Acasta gneisses and Nuvvuagittuq belt, Superior Province, Trans-Hudson Orogen, Grenville Province, Mid-Continental Rift, etc.). The course consists of 16 classroom lectures, 8 labs and a field trip to Timmins. PREREQ: GEOL 2807/3807 (Geochemistry), GEOL 3206/3207 (Petrography), and GEOL 3306 (Structural Geology).
