The main regularities of the tectonic history of the Circumpacific belt's Asian segment are discussed._x000D_
The established longitudinal metallogenic zoning is characterized by essential copper specialization being replaced in the.continentward direction by tin-tungsten and then by copper-gold-molybdenum and-tin-lead- zinc ones. The zones indicated show specific magmatism and ore forming fluid composition. The eastern margin of Eurasia experienced specific tectonic history and exhibits a wide variety of mineral deposits. It is composed of the Siberian and Sino-Korean cratons and of the largest mobile elements of tectonosphere like the Hyperborean, Urals-Mongolian, Mediterranean and Circumpacific belts. The Earth's Atlantic segment mobile features show deep penetration of their geosyncline-fold systems into the eastern margin of Asia. A good example is the Urals-Mongolian belt, its Intra-Asian branch being located within the continental margin. The Intra-Asian structural features have WE and NE trending, while folding process moved southward : Karelides and Baikalides are found in the Transbaikalia and the Soviet Far East (Stanovoy, Bodaibo-Patom, Baikal- Vitim, Selenga-Yablonovy fold regions)
