Age and geochemistry of basement complexes in the south-central New Québec Orogen: Archean history, terrane correlations, and Paleoproterozoic reactivation

Canadian Journal of Earth Sciences, Ahead of Print.U–Pb geochronological, geochemical, and Sm–Nd isotopic data from metaplutonic rocks in the south-central New Québec Orogen (NQO) provide new insights into the long-term tectono-magmatic evolution of western Labrador. Basement units are divided into two complexes—the Snelgrove Lake Basement Complex (SLBC), exposed beneath sedimentary rocks of the Labrador Trough, and the Griffis Complex—separated from each other by
