Abstract <p>Magnetostratigraphic data on the Klyuchevskaya Member and the lowermost of the Lower Syzran Subformation, which composed the lowermost of the Paleocene (Danian Stage) in the north of the Volga Right Bank Region near Saratov, are determined for the first time. A stratotypical section of the Klyuchevskaya Member near the settlement of Klyuchi and the section near the settlement of Tyoplovka are characterized by magnetozones of different polarities: the analogs of chrons C29n, C28r, and C28n, on the basis of which the Klyuchevskaya Member is compared with the NP2–NP3 zones by calcareous nannoplankton. The sedimentation rates and the period of the formation of the deposits are estimated. The presence of differentiated tectonic movements at the beginning of the Paleocene is substantiated by results of detailed magnetostratigraphic correlation of sections, as well as geochemical data, and gentle inclination of the bottom of the early Danian basin to the southwest is suggested from anisotropy of magnetic susceptibility.</p>
