Аннотация:We present the rock-magnetic and palaeomagnetic results of the Sarmatian-Maeotian (UpperMiocene) sediments of the key sections of Cape Popov Kamen and Cape Panagia from Taman Peninsula(Eastern Paratethys) and forming the flanks of a single synclinal fold. A three-component composition ofmagnetization has been detected. The first is the viscous component A, the second is the component B, whichis intermediate between the components A and the third component C, which tends to zero in the Zijdervelddiagram. The directions of component B are characterized by northern–northeastern–eastern declinationsand positive inclinations in the stratigraphic coordinate system; the fold test for the Popov Kamen andPanagia results is negative, and the magnetization is post-folding. The directions of component C have negativeinclinations and southern declinations in the stratigraphic coordinate system. Paleomagnetic results fortwo sections showed the test fold positive, magnetization preliminary and the magnetization is pre-folding.Components B and C, on the basis of which the polarity of the magnetozones is determined, are of differentages, and the palaeomagnetic record of component B is the result of complete or partial remagnetization,which makes it impossible to use magnetostratigraphy for section dating. Our work affects an important questionabout the reliability of palaeomagnetic data on the Miocene deposits of the Kerch-Taman region (EasternParatethys).
