The southeastern part of the Ukrainian uplift and the Caspian region basin together with the adjacent parts of the Volga-Ural uplifts, the Voronezh uplift and the system of depressions of the Cisural basin are the main structural-tectonic elements of the southeastern part of the Russian platform. The folded framing is composed of the Ciscaucasus--Kopet-Dag Epihercynian platform of the western part of Tien Shan, the Southern Ural and the southern part of the Turgay depression. The magnetic field, characteristic of this territory, is probably connected with sources situated in the crystalline base Kasatkin, 1965. We assume that within the limits of the Russian platform and the northern Ciscaucasus-Great Donbas the base belongs to the Precambrian age. In the northern part of the territory of Southern Ciscaucasus-Stavropol region and the Ciscaucasian foredeep the base also belongs to the same age, while in the remaining part it belongs to the Paleozoic age, apparently to the Pre-Upper Devonian period. In the Transcaspian region, which includes parts of the Southern Ural and Tien Shan, the base belongs to the Pre-Upper Devonian period, while on the Southern Ural partially and in the Western Tien Shan it belongs to the Post-Middle Devonian Hercynian period. The sources of the magnetic anomalies are mainly bedded in the roof of the crystalline base, however some are situated within it, mostly in the depressions of the roof.
