The article presents the results of paleomagnetic studies of Pliocene-Pleistocene deposits of the Ajinokhur structural zone. To obtain the paleomagnetic characteristics of these deposits, comprehensive experimental investigations were conducted, which made it possible to construct a magnetostratigraphic scale of the Pliocene–Pleistocene strata of the studied sections. To study the paleomagnetic properties of Pliocene-Pleistocene rocks, about 300 oriented samples were studied. he magnetic susceptibility and the natural remnant magnetization of the deposits vary between 3.1 x 10-3 - 7.6 x 10-3 BS and 5.9 x 10-3 - 36.1 x 10-3 A/m, respectively. The average value of the permanent component indicates that the mag-netization is close to its initial value and can therefore be used to compile a paleomagnetic scale. Within the investigated area, the identification of regional magnetostratigraphic reference points in the Upper Pliocene–Pleistocene deposits has been substantiated, including the boundaries between the Productive thickness and the Akchagyl, the Akchagyl and the Absheron, and the Absheron and the Baku. The studied deposits have been subjected to age subdivision.
