Figure 7. Seismic reflection line offshore Banks Island showing Jurassic and Lower Cretaceous synrift strata unconformably overlaying Devonian prerift clastics below the basement reflector. Synrift strata document the earliest phase of rifting in the Canada Basin as the Alaska–Chukotka microcontinent rotates away from Arctic Canada. The region was dominated by backstepping and low sediment input until the latest Cretaceous–earliest Paleogene. Note major aggradation and progradation above the Eocene reflector documenting a major increase in sediment supply to the margin. See Figures 1 and 6 for line location.
