Abstract

The article presents a structural-formational (tectono-stratigraphical) and metallogenic map of the Greater Altai, that covers not only the territory of the Russian Federation (structures of the Southwestern and Gornyi Altai) and Eastern Kazakhstan (Irtysh-Zaisan folded system) (the part that was compiled by the authors earlier), but is also extended for the territory of the Mongolian and Chinese Altai. It is shown that structures of the Gorny Altai, Southwestern Altai, and the Irtysh-Zaisan folded system (and their corresponding structural-formational zones) continue to the territory of the Mongolian and Chinese Altai. For each of the structural-formational zones, the composition of their constituting sedimentary and volcanosedimentary sequences, their formational type, geological age, and ore-formation types of the ore deposits distributed within their limits are given.
