Abstract
The article considers the peculiarities in the geotectonic development and ore potential of geological structures in Southern Altai, Eastern Kazakhstan. The territory encompasses the southeastern flanks of the tectonic zones of Rudny Altai and Kalba of Greater Altai, which are part of the overall system of the Central Asian mobile belt. The spatial adjacency of geological and ore-bearing structures of different ages and composition is emphasized, which were subjected to intense metamorphic and hydrothermal–metasomatic alterations under the influence of the Dzungarian massif and Siberian Plate and subsequent thrust–strike-slip deformations. The iron ore, copper, polymetallic, gold, and rare metal deposits formed in various geodynamic settings are characterized. The ore-controlling factors and criteria for forecasting and prospecting for ore objects are noted.
