...M. V. Lebedev; L. S. Chernova This article deals with the fades models for a Vendian clastic complex in the northeastern Nepa-Botuoba Anteclise (Siberian Platform). The main method of investigation is fades modeling. It is based on the interpretation of sedimentary basins as geological systems...

... processing of data for the western slope of the Nepa–Botuoba anteclise. Further testing of SG methodology within industrial data processing was performed in ( Kochnev et al., 2016 ). The applicability of the methodology will be illustrated by the results obtained for section No. 2 (around 40 km...

The Betinche Formation is composed of quartz and quartz–feldspar sandstones and siltstones lying on the foundation or terrigenous-dolomite Talakan Formation. The Khorongsk Formation...

...–Botuoba uplifts, and all deposits of the Tira stage and a part of the Nepa stage were denuded on the Kamov Arch in the Baikit uplift and on the Nepa Arch of the Nepa–Botuoba anteclise ( Fig. 6 ). The Pre-Nepa gap was about the same duration and intensity, which allows us to assign the Nepa and Tira...
