Magnetostratigraphy of Turonian - Santonian strata on the Samara Right Bank
The paper presents the results of petro- and paleomagnetic studies of two sections of Turonian - Santonian on the Samara Right Bank - near Novodevichye, Podval’e villages and detailed geological description of the Novodevichye section. The magnetostratigraphic subdivision and detailed correlation of the sections were carried out. Unknown unconformity in the Podval’e section was recognized. Reverse polarity corresponds to a significant part of the Coniacian - Santonian deposits, the presence of which contradicts the existing ideas about the regime of the Turonian - Santonian geomagnetic field, but partly agrees with the data on deposits of the same age found in other sections in the Volga region.
