| Abstract: | One of the reference sections of Maeotian deposits in the south of Russia (the Popov Kamen section) is studied in terms of rock magnetism and paleomagnetism within the framework of the project “Study of Reference Sections of the Taman Downwarp as a Basis for Developing a Detailed Event Scale of the Neogene of the Eastern Paratethys.” The section is located in the southwestern part of the Taman Peninsula, to the south of the Taman Cape. It has been established that the lower-Maeotian deposits carry the magnetization of mainly reversed polarity, whereas the upper-Maeotian deposits are characterized by normal polarity. Two horizons of normally magnetized rocks are recognizable against the background of reversely magnetized lower-Maeotian deposits. A horizon of reversely magnetized rocks is outlined in the upper part of the upper Maeotian. If the paleomagnetic interpretation of the section is true, it can be concluded that the upper part of the upper Maeotian is absent in this section. Comparison with the magnetochronological scale shows that the lower Maeotian probably corresponds to the C3Br, C3Bn, and C3Ar Chrons, and the part of the upper Maeotian studied in this section corresponds to the lower part of the C3An Chron. |
