Abstract

The middle to late Proterozoic basins of northern Canada have hitherto been viewed in isolation, mainly owing to their geographic separation, disparate stratigraphic histories, and different inferred depositional ages. Detrital zircon geochronology and carbon isotope chemostratigraphic correlation, together with sparse new depositional age constraints, are bringing both assumed and unexpected equivalences into focus and allowing the chronology of subsidence and sedimentation to be deciphered and compared for  three major basins: Amundsen basin (Shaler Supergroup; northeastern NWT and western NU), Mackenzie basin (Mackenzie Mountains Supergroup; west-central NWT and east-central YT), and Bylot basins (northeastern NU).
