摘要
Based on analysis of new data on the geodynamical nature, ages of formation, and magmatic sources of contrasting rocks from the tectonic m,lange of the Yenisei shear zone, the chronological sequence related to early stages in the evolution of the Paleoasian Ocean was established. The data obtained specify the legend and stratigraphic scheme of the Yenisei Group and peculiarities in the evolution of the Sayany-Yenisei accretionary belt at the final stage of its Neoproterozoic history.
