Age and tectonic implications of Paleoproterozoic granitoid intrusions within the Nain Province near Nain, Labrador
U-Pb (zircon) age determinations from three granitoid intrusions in the Nain region, formerly assigned to the well-known 1.35-1.29 Ga (Mesoproterozoic) Nain Plutonic Suite (NPS), indicate that they were emplaced, instead, during the Paleoproterozoic.
