On November 15, 2017, the republic seminar on Earth Sciences on “Kinematic parameters of the tectonic movements of the southeastern part of the Greater Caucasus and adjacent regions (based on new paleomagnetic data)” was held in the Institute of Geology and Geophysics of ANAS.

Deputy Director in science, corresponding member of ANAS Dadash Huseynov opened a meeting and spoke about the importance of this research. The report was prepared by the Head of the department of geomagnetism, Dr. in Geology and Mineralogy, Pr. Manija Isayeva and Ph.D. in Geology and Mineralogy Takhmina Garayeva. The report was presented by T. Garayeva.

T. Garayeva reported that paleomagnetic methods are widely used in solving of tectonic problems, in study of local deformation and separate massifs rotation, in problems connected with horizontal movements of lithosphere plates and with global reconstructions.

The results of integrated studies of the volcanogenic-sedimentary and sedimentary rocks of the Meso-Cenozoic allow to compare the regions with similar geological structure, to synchronize and reconstruct the geological events on a wide scale, to get more extensive information about the history of the geomagnetic field during relevant period.

The reporter noted that samples were taken from Lahij, Vandamian and Sumagaly sections, as well as from Khodjashen, Khudbarekdag and Beyuk Dakhne depressions of the southeastern slope of the Greater Caucasus, from Goychay, Turyanchay and Girzan sections of the upper part of the Kura depression, from Korgez and Garangush sections, and from Gurd Gapysy section of Absheron Peninsula. The studies focused on the study of the kinematic parameters of sections blocks movements are conducted.

The analysis of the southeastern part of the Greater Caucasus and adjacent regions showed the increase of blocks translational velocity and of blocks turns from South-East to North-West due to highest values of intensity and geodynamic activity of the Greater Caucasus. On the base of paleomagnetic data it was determined that the velocity of blocks horizontal movements is different, that’s why the collision of separate parts of crustal blocks leads to significant margin deformations of the massifs.

Seminar’s members heard with interest to the report.
