—Using new computer technologies for the northern part of the South Urals, the structural features of the anomalous magnetic field have been studied, magnetic anomalies from different layers of the Earth’s crust have been identified, and corresponding volume models of the sources of anomalies (the boundaries of basite–ultrabasite massifs, deep-seated belts, and basalt layer) have been constructed. The new data on the structure of the South Urals Earth’s crust make it possible to clarify the position of deep faults and their connection with deep-seated basite–ultrabasite belts. Deep-seated root blocks have been identified for large hyperbasite massifs. Within the Taratash anticlinorium, the constructed models of the sources of magnetic anomalies allow us to conclude that the oldest Taratash complex in the Urals is an elevated part of the deep-seated basite–ultrabasite belt of the East European Platform.
