HEAT FLOW OF THE EARTH’S CRUST OF THE NORTHERN TIEN SHAN

Abstract

The energy aspects of modern geodynamic processes are considered in the article on the basis of the study of the deep thermal heat flow of the Northern Tien Shan. A brief description of the geological structure of the lithosphere of the region is given. Data on the parameters of the heat flow of the earth's crust are generalized and systematized. These included definitions that were obtained by measuring the thermal conductivity of rocks and the temperature gradient in the recovered boreholes. Data from the World Data Center and experimental material on the geothermal properties of rocks from open publications are also included. The heat flow map of the territory is given. The features of the local heat flow in comparison with the world average data for continental tectonically active regions are analyzed. Analytical relationships between the heat generation of rocks due to the decay of radioactive elements and the propagation velocity of the crustal waves of the Northern Tien Shan are established. The regularities of the formation of heat-generating elements with depth are discussed. Models of distribution of mantle and radiogenic heat flow in the volume of the earth's crust are presented and discussed. A comparative analysis with manifestations of seismic activity of the territory was carried out. An opinion is given on how to influence the formation of the seismic regime.
