As a result of generalization and analysis of complex geological and geophysical data, the geophysical studies were shown in application to structural mapping of ore-prospective areas and detailed study of ore-controlling complexes of cupreous sandstones in the Zhezkazgan ore district of Central Kazakhstan. Basing on modern means of registration, processing and interpretation of magnetic, gravity and seismic exploration, the ore geophysics proved its efficacy in studies of tectonic structure of ore areas, localisation and identification of the morphology of differentiated intrusive massifs at depth, detection and deep mapping of tectonic faults, defining the ore-controlling structures of sedimentary and effusive-sedimentary folded complexes as well as in determination of the spatial position of ore-bearing zones.The deep structure of the Zhezkazgan syncline on sides of the Sary-Oba rise differs sharply, fixing the simple structure of the eastern part and the complex folded one of the western part. The deposits of the Zhezkazgan and overlying zhidelisai and kingir suites represent a conforming continuous section, in places, there are local disconformities over faults with repeated tectonic displacements, lying on sediments of the taskuduk suite. Taking into account the rather complex geological structure of the given ore district and the significant differentiation of the composing rocks, ores and near-ore hosting strata, further identification of additional criteria for localization of copper mineralization is possible with the integration of detailed geological and geophysical methods, geochemical and physical-chemical studies of rocks and ores.
