Figure 3. The Triassic was dominated by overall regression. The paleo-Pacific was characterized by deep-water, passive margin conditions receiving sediments from large Laurentian and Siberian rivers. The relatively shallow, intracratonic central Arctic basin was mainly supplied not only from the Polar Urals, but also from other local sediment source areas. The Alaska-Chukotka microcontinent was a relatively small source area feeding sediment into the Sverdrup Basin, the Hanna trough area and the South Anyui ocean. The long-dashed routing system illustrates possible sediment transport from the West Siberia Basin to the North Kara Basin and eastern Barents Sea prior to Late Triassic–Early Jurassic uplift of Novaya Zemlya. The short-dashed routing system illustrates the trans-Arctic routing system as suggested by, for example, Miller et al. (2013) and Anfinson et al. (2016). F.J.L. = Franz Josef Land; NSI = New Siberian Islands; WI = Wrangel Island.
