Pervushov E.M., Ryabov I.P., Guzhikov A.Yu., Seltser V.B., Kalyakin E.A., Fomin V.A. (2023) Bio-Magnetostratigraphy of the Turonian–Coniacian Deposits of the Lower Bannovka Section, South-East of the Russian Plate // Stratigraphy and Geological Correlation, Vol. 31, Suppl. 1, pp. S52–85.
—The lithological, paleontological and biostratigraphic characteristics of the Turonian–Coniacian deposits of the Lower Bannovka section, the stratotype of the Bannovka Formation (Volga region, Turonian) are presented. Magnetostratigraphic characteristics of thе sediments have been supplemented and elaborated. Petromagnetic data contribute to more refined stratigraphy of the section and facilitate the revealing of depositional rhythmicity. Paleomagnetic data combined with benthic foraminifera data enable the most detailed correlation of the Turonian–Coniacian deposits in the Volga region. Results of a comprehensive study of this stratigraphic unit within the southeastern arch of the Ulyanovsk-Saratov trough revealed patterns in the distribution of the Gubkino Horizon, determined by regional tectonics and processes preceding deposition in the Coniacian and Santonian
