This study presents 48 new U-Pb and 35 new K-Ar dates for magmatic rocks of the Coast Plutonic Complex (CPC) between 53°N and 54°N. The eastern flank of the CPC is underlain by the Gamsby Complex, an early Late Jurassic (160-155 Ma) magmatic, metamorphic and ductile compressional belt superimposed o...
