Abstract
Abstract—The results of the analysis of the core and logs of the Upper Vendian sediments (Vilyuchansky, Nepsky, Tirsky, and Danilovsky horizons) of the northeastern part of the Nepa–Botuoba anteclise are presented. The regional sequence-stratigraphic analysis made it possible to identify six third-order sequences and stratigraphic unconformities confined to their boundaries. The system tracts are represented by proluvial, alluvial, lagoonal, and shallow-water–marine sediments, which successively replace each other. This is typical of the passive continental margin environments and the general subsidence of the Siberian Platform in the Vendian.
