Preliminary Results of Summer 2019 Fieldwork in the Northwestern Pontiac Subprovince, Rouyn-Noranda Area, Quebec

In this report, partial results from fieldwork of a Ph.D. project conducted by the lead author in summer 2019 are presented. The study area (Figure 1) is located approximately 9 km south of the city of Rouyn-Noranda, Québec. The aims of the project were to constrain the extent to which the fluids released during Barrovian metamorphism (from the biotite to the sillimanite zone) of the northwestern Pontiac Subprovince contributed to the significant endowment in gold of the Cadillac–Larder Lake fault zone (CLLFZ)—a world-renowned gold district in the Abitibi greenstone belt. Further constraining the metamorphic evolution of the Pontiac Subprovince will also provide an opportunity to better understand its geodynamic significance.
