Abstract

The main purpose of the conducted research was to determine the prospects of the ore areas of the Aldan-Stanovoy Shield for identifying new gold ore objects in the zones of development of products of regressive metamorphism. The materials obtained during prospecting and exploration works in different years were used. The processes of diaphoresis manifested on the territory of theAldan-Stanovoy Shield, composed of metamorphic complex-dislocated complexes, were considered, the types of dia uorites and their features were established. A review of the results of previously conducted geological studies to identify the manifestations of gold of different ranks associated with the zones of dia uorites was made. The extremely insuf cient study of the territory of the Aldan-Stanovoy Shield for ore gold in Precambrian formations was established. The main areas of the Aldan- Stanovoy Shield have been identi ed, where zones of dia uorites have been identi ed and contoured in different years. The tectonic and geochemical factors of control over the manifestation of regressive metamorphism and associated ore formation were revealed. The connection of dia uorosis with ore formation and metallogemc special ization of dia uorites of promising ore areas of the shield was established. Based on the available data, including the results of geochemical searches conducted in different years, a forecast was made for the detection of new gold ore occurrences in the ore-bearing and gold-bearing areas of the Aldan-Stanovoy Shield. Promising areas were identi ed for conducting priority prospecting and exploration work for gold and determining their metallogeny.
