A new version of the Regional stratigraphic chart for the Silurian of West Siberia and explanatory note, compiled in accordance with the Russian Stratigraphic Code, introduce changes, additional and specified data in comparison with the previous chart, adopted as Silurian section of the composite Stratigraphic chart of Paleozoic of the West Siberian Plane approved as the official stratigraphic basis for all types of regional geologic activities. After the meeting in 1998, the Silurian International Standard Stages were completely updated. In accordance with the updated International Standard Stages, in 2012, the Regional stratigraphic chart for Devonian of the West Siberia and a Regional stratigraphic chart for the Cambrian of the Cis-Yenisei part of West Siberia were adopted and approved. In 2020, the Regional stratigraphic chart for the Ordovician of West Siberia was adopted and approved. New paleontological, stratigraphic, lithological, and seismostratigraphic materials on the Silurian deposits of West Siberia have been obtained and generalized. For the first time, an inclusive Regional stratigraphic chart for the Silurian of West Siberia has been compiled.

Keywords: West Siberia, Silurian, Regional stratigraphic chart, explanatory note.
