We present the results of detailed paleomagnetic studies of six Permian-Triassic boundary sections in the central part of the East European Platform, located in the lower reaches of the Vetluga River: Astashikha, Voskresenskoe, Znamenskoe, Prudovka, Sosnovka, and Sukhoborka. The paleomagnetic data, which meet the modern quality standards for laboratory processing, together with the results of biostratigraphic studies, allow for the development and substantiation of magnetostratigraphic scales for each section, as well as for their correlation and the construction of a magnetic polarity scale for the Permian-Triassic sedimentary complex of the Vetluga River. Rock-magnetic characteristics are determined for each of the studied sections, and paleomagnetic poles of the East European Platform are calculated for the Late Permian and Permian-Triassic boundary.
