Summary. In the paper, the results of the study of Paleogene sediments in the territory of the Nakhchivan Autonomous Republic, the horizontal movements of the Earth's crust, and the solution to the problem are given. Paleomagnetic studies were carried out in two transects, Aza and Andamich, and Paleogene sediments were studied. Initially, the kinematic parameters and horizontal movements of the blocks are determined based on the paleomagnetic data. The discussion of the results of the paleomagnetic research conducted in the territory of the Nakhchivan Autonomous Republic was carried out on rocks of the Paleogene age.

Similar results were obtained while characterizing the components of In: clays, fine-grained sandstones are more stable, coarser-grained rocks are metastable, and coarse-grained sandstones, marls, siltstones, etc., are unstable. On average, they have the same direction as the magnetization direction, as determined by the cross-sectional method.

The sections show a regular alternation of rocks with direct and reverse magnetization. After temporary and temperature cleaning, as well as alternating magnetic cleaning, in the Aza and Andamich sections, both directly and reversely magnetized rocks have the same direction. All this indicates the synchronism of Inº and the absence of the secondary magnetization components in In after cleaning. The relevance and importance of the paleomagnetic studies conducted are also noted; only through this method is it possible to determine the paleotectonic positions and quantitatively assess the rotations of certain geological structures on others.

Keywords: Magnetic susceptibility, stratigraphic division, geological-geophysical analysis of the Ordubad synclinorium, Andamich sections, Paleocene epoch
