Abstract

The article presents GPS monitoring data for the territory of Azerbaijan. It has been established that the velocity of the Earth’s surface in depression zones is significantly higher than at the junction of large tectonic elements, where the Earth’s surface moves in a rotational manner (counterclockwise and clockwise). It is assumed that the decrease in the velocity of the Earth’s surface in the junction zone of the Kura Trough with the Greater Caucasus is associated with the influence of tectonic compression forces in the horizontal direction on the formation of young uplifts that form a series of parallel ridges of Cenozoic age, and the compaction of tectonic breccias formed as a result of friction between the fold system of the Greater Caucasus and Kura Trough. The clockwise rotation of the Earth’s surface in some areas of Southeastern Gobustan is associated with narrowing of the total area of the platform, which are overlain by Cenozoic sedimentary layers, fragmented into separate blocks as a result of mud volcanism. This occurred as a reaction of the Earth’s crust to the force of horizontal compression created by convergence of the Eurasian and Arabian plates.
