Magnitostratigraphic studies of the Upper Sarmatian-Lower Maeotian deposits in the Panagia Cape section (the Taman Peninsula)

Abstract

In order to obtain the missing data on the magnetostratigraphy of transitional layers between Sarmatian and the Maeotian parts in the Eastern Paratethys, the authors studied the Upper Sarmatian ― the Lower Maeotian deposits in the Panagia Cape section (the Taman Peninsula, Russia) using petromagnetic and magnetostratigraphic methods. The Panagia Cape section is located on the Black Sea coast of Taman Peninsula. The total thickness of the studied sediments is about 29 m. The section is composed mainly of clays characterized by weak magnetization. Natural remanent magnetization is caused mainly by monoclinic pyrrhotite. Magnetic anisotropy was studied in order to substantiate reliability of the results. Comparison with the ATNTS 2012 magnetochronological scale shows that the studied transitional layers between Sarmatian and Maeotian parts probably correspond to the 4n, 3Bn and 3Br Сhrones. The obtained results agree with biostratigraphic and radiometric data.
