Assessment of geothermal energy resource potential based on aeromagnetic survey of Tamdytov mountain range (Central Kyzylkum)

Abstract

This study is dedicated to assessing the prospects of geothermal energy resources in Tamdytau and adjacent areas of Central Kyzylkum based on aeromagnetic data. In the study, based on spectral analysis of aeromagnetic data at a scale of 1:100 000, the depth boundaries of magnetic sources and the depth of the Curie point were determined, and the geothermal gradient and territorial distribution of the heat flow were estimated. According to the results, the depth of the Curie point is 3.8 – 7.8 km, the geothermal gradient varies within 75 – 160 °C/km, and the heat flux is within 190 – 390 mW/m². The highest geothermal indicators are identified within the range of 41.6 – 41.8° northern latitude and 64.5 – 64.7° eastern longitude, and this zone corresponds to the territories of the Balpantau, Tamdybulak, and Kinir gold deposits. The identified anomalous zone indicates a link between geothermal processes and the geological structure and mineralization of the region. The research results demonstrate the effectiveness of identifying geothermically promising zones based on aeromagnetic spectral analysis and justify the need for their detailed study using thermal logging and magnetotelluric studies.
