Figure 16. Interpreted seismic section from the East Siberian shelf. The Khatanga–Bering transform influenced basin topography and deposition in the area. Lower Cretaceous strata may be preserved in the distal part of the basin but the section is inferred to be thin or absent on the shelf. The lower part of the Cretaceous section may represent sediment delivery from the Verkhoyansk fold belt prior to opening of the Eurasia Basin. Later, sediments were derived from the eastern part of the Chukchi fold belt. The basement on the East Siberian shelf is inferred to contain late Paleozoic–Triassic volcanics, which were eroded and transported to nearby basins when the area was part of the Alaska–Chukotka microcontinent (ACMC). Modified from Sekretov (2001). See Figures 1 and 15 for line location.
