Abstract
Petro- and paleomagnetic studies of the Quaternary marine deposits in the Malyi Kut section (the Krasnodar Krai, the western Taman Peninsula) were performed in the 425-375 ka time interval. A complex of rock magnetism methods was used to determine the composition, domain structure, and concentration of ferromagnetic fraction grains that are present in the studied rocks. The directions and reliability of the distinguished directions of natural remanent magnetization were studied. A horizon with an anomalous magnetization behavior (∼395-375 ka) was detected at the end of the Lower Pleistocene. Such a magnetization behavior was observed at the top of the transgressive deposits in the Urundzhik horizon of the Karadzha section (oxygen isotope stage 11) and was assigned to ∼400-375 ka. The Biwa-III excursion corresponds to this interval of an anomalous magnetization behavior.
