Cretaceous strike–slip displacement along the Porcupine fault system and potential links to the opening of the Canada Basin

Canadian Journal of Earth Sciences, Ahead of Print.Tectonic models for the evolution of the Canada Basin of the Arctic Ocean posit Jurassic–Cretaceous counterclockwise rotation of the Arctic Alaska terrane away from the Canadian Arctic Islands, translation along a strike–slip fault system, or some hybrid combination of the two. Here, we present evidence for post-Devonian deformation within the Porcupine fault system of northern Yukon and Alaska, which forms the southeastern boundary
