Abstract

2D and 3D modeling of sedimentation in Cenozoic clinoform complexes in the North Chukchi basin has been performed. There are two clinoform complexes in the North Chukchi basin: lower complex (Paleocene–Eocene complex) and upper complex (Oligocene complex). Orogens of Alaska and Chukotka are the source of sedimentary material for the clinoforms. Two-dimensional modeling of the upper clinoform complex has been performed and sea level fluctuations necessary for the formation of clinoforms have been determined. Possible source areas and quantitative characteristics of the input of sedimentary material have been determined based on the results of three-dimensional sedimentation modeling. The rivers that supplied sediments in the Oligocene are comparable to the modern Kolyma and Northern Dvina.
