This work presents a generalization and analysis of the physical properties of rocks and ores from the Zhezkazgan ore district. Studies were carried out to identify general patterns in variations in the magnetic, density, velocity, and electrical parameters of the rocks that make up the geological section of the region. Based on the physical parameter measurements of the rock samples and drill cores collected in large quantities evenly throughout the region, a spatial analysis and quantitative assessment were conducted for the magnetic susceptibility, density, specific electrical resistivity, polarizability, and seismic velocity of the rocks. These properties were systematized at the level of formations, individual suites, and lithological heterogeneities. Correlations between the physical properties of the rocks, their composition, and the conditions of their formation were established. This study demonstrated the potential of using petrophysical characteristics in tectonic studies, geological mapping, and the identification of the exploration and ore-controlling factors in copper mineralization. It was found that the deposits of the productive horizons of the Zhezkazgan and Taskuduk suites are characterized by consistent physical parameters across the entire area, due to their relative homogeneity in lithological, structural–textural, and other features. The physical parameters of the rocks are influenced by several factors associated with mineralization processes, including changes in the total porosity, structure, and texture of the host rocks, alteration of the original mineral composition of the ores, fragmentation, fracturing, fissuring, and others. The obtained results significantly improve the reliability of geologically interpreting geophysical anomalies, especially in areas covered by loose sediments and where productive horizons are deeply buried. The detailed petrophysical analysis of the region has made it possible to provide recommendations for selecting an optimal set of geophysical methods for further successful work at the prospecting-evaluation and exploration stages in the Zhezkazgan ore district.

This study presents the results of a detailed investigation of earthquake focal zones in Eastern Kazakhstan using modern methodologies for determining focal parameters and focal mechanisms. The stress regime and the elastic stress field of the Earth’s crust were analyzed based on seismic events recorded during the period 1990–2020. An information base was established for the investigation of regional deformation conditions using earthquake focal mechanism catalogs and data acquired from the regional seismological monitoring network. The installation of new seismic stations along the perimeter of Kazakhstan has enabled a more detailed investigation of seismicity in Eastern Kazakhstan and an assessment of the stress–strain state of the deep layers of the Earth’s crust in the region and adjacent territories. An electronic database of stress tensor parameters and seismotectonic deformation increments was developed using the method of cataclastic analysis of seismic data implemented in the STRESS seismic software package. The stress–strain state of the Earth’s crust was analyzed based on the spatial distribution of stress tensor parameters and seismotectonic strain increments. Zones characterized by contrasting stress regimes were identified, along the boundaries of which strong earthquake sources are most likely to occur. Analysis of the orientations of the principal stress axes indicates a reset-type stress regime.
