Figure I: Geographical features and the main structural elements of the eastern Russian Arctic continental
margin and adjacent regions. Polar stereographic projection. The italic capital letters show location of the
physiographical features: LD - Lena Delta, YIL - Yana-Indigirka Lowland, AP - Arlis Plateau, CAP - Chukchi
Abyssal Plain, CG - Charlie Gap, CP - Chukchi Plateau, NG - Nautilus Gap, NR - Northwind Ridge. Outlined
bold capital letters denote the structural elements: KM - Kara Massif, TFB - Taimyr Fold Belt, LRS - Laptev
Rift System, NR - New Siberian Rift, DU - De Long Uplift, VT - ViI 'kitskii Trough, W A - Wrangel Arch, HA
- Herald Arch, LNP - Listric-normal faults province, CB - Chukchi Borderland. Outlined bold numbers denote the
time of the spreading events in the Arctic oceanic basins in millions of years.
