We discuss the current understanding of the Vendian Regional Stages in the northeast of the Nepa-Botuobiya Anteclise, establish a new correlation of the Vendian sections across different facies, and propose stratotypes for the introduced stratigraphic units. A new stratigraphic chart is constructed for the Vendian terrigenous strata in the northeast of the Nepa-Botuobiya Anteclise and the adjacent territories
