Figure 12. Seismic reflection line across the North Slope foreland basin showing thick, downlapping shelf–slope wedges of Aptian–Albian age above the base Cretaceous unconformity. Detrital zircon and paleocurrent data suggest that the sediments mainly were derived from Chukotka in the northwest. Also note downlapping Jurassic shelf–slope wedges between the top Triassic and base Cretaceous reflectors, indicating sediment dispersal from a different source area at the flank of the early Canada Basin (Barrow arch) or Arctic Canada to the southeast. See Figures 1 and 10 for line location.
