Abstract
Correlation of the Permian continental and marine deposits of Northeastern Russia, the southern Far East, Siberia, and the Pechora Сisurals is carried out. A consistent zonal succession of brachiopods, marine bivalves, and ammonoids is revealed and linked with the macroflora in the boundary deposits of the Cisuralian/Biarmian Series of the Boreal Superrealm. As a result, analogues of the Solikamian, Irenskii, Filippovskii, and Saraninian Horizons of the Kungurian Stage are established in the main coal basins and marine sequences of Northeastern Russia and the southern Far East. The correlative floristic horizon, stretching from the east of the East European Platform to the Pechora Cisurals, Pai-Khoy, Siberia, the Kuznetsk Basin, Northeastern Russia, and the southern Far East is established. The unity of the Sheshmian–Kazanian nonmarine floral assemblages and nonmarine bivalves, which correspond to the marine biota of Kazanian age, and their distinction from Kungurian assemblages are established. The Kungurian–Kazanian boundary is traced in marine and continental deposits within the entire Boreal Superrealm. The invalidity of the Ufimian Stage is established. The Kazanian Stage corresponds to the Roadian Stage of the International Chronostratigraphic Chart; however, the lower boundary of the Kazanian Stage is not defined precisely and can be conventionally considered isochronous to the boundary of the Roadian Stage.
