Аnnotation: Data on the physical properties of rocks and ores of the Northern Bukantau structural and formational subzone of the Bukantau Mountains are considered in order to conduct the geophysical search and exploration of ore deposits. In the Central Bukantau subzone, a late Proterozoic metabasite intrusive complex is conditionally identified, which is characteristic of the entire zone of the Bukantau deep fault. It is represented by listvenized serpentinites, various rocks and products of their further transformation, including small bodies in the axial part of the deep fault zone, among the mixed tectonic rocks. The Southern Bukantau is a structural-formational subzone. In this subzone, the most ancient rocks are in the upper Proterozoic Cholcharatau Formation. This formation is a volcanogenic-sedimentary intensively metamorphosed stratum consisting of gabbro-diabases, diabases and their tuffs transformed into amphibolites, amphiboles and various crystalline shales, with an apparent thickness of more than 400 m. The presence of intrusive rocks of variegated petrographic composition is observed in the territory of Northern Bukantau, which is due to the position of this area within the regional resonant-tectonic system of the Kuramino-Ferghana middle massif. Southern Bukantau is more complex, and terrigenous deposits of different compositions and carbonate rocks are developed here. The sedimentary formations are interrupted by numerous acidic intrusions, which are exposed on the surface.
