ABSTRACT
The Altai-Sayany folded region is characterized by a long history of exploration and mining of gold. Here several metallogenic zones and clusters of gold mineralization are distinguished, varying in formation conditions and age. Based on analysis of the isotope-geochronological, geological and metallogenic data one can distinguish five metallogenic epochs in the formation of gold ore potential within the Altai-Sayany folded region. The gold mineralization of Permian-Triassic age is the least studied within the Altai-Sayany region. The Permian-Triassic age of gold mineralization is determined in those areas, where the gold mineralization is superimposed on a relatively young rocks of Late Paleozoic and Early Mesozoic ages. There are several sites (Kundel, Konyukhta, Legostaevo) with established Permian-Triassic gold mineralization. The article presents the characteristics of the such sites containing the Permian-Triassic gold mineralization. The conclusion is made about the widespread gold mineralization in the Altai-Sayany folded region. This type of mineralization takes its regular position in a number of different mineralization types of this metallogenic epoch. The formation of such mineralization probably is concerned with plume mantlecrustal basic and granitoid magmatism.
