Аннотация (краткое описание)
The Big Karatau is a recognised major mining region since the mid-XX century, with discoveries of not only lead and zinc deposits, but also those of gold, vanadium, granular phosphorites, barite and others. According to the Mineral Resources Development Programme, the Republic of Kazakhstan (RK) is one of the world’s top ten countries in terms of ferrous and non-ferrous metal reserves. However, a significant part of the reserves seems to be uncompetitive for the fact that production volumes exceed the growth rate for almost all types of minerals. Considering that it takes at least 15 years from prospecting to development preparation, development of critical situation is expected in the RK copper, lead-zinc and gold-ore sectors in near future. On the other hand, the production decline has already led to socio-economic problems. Over the last ten years mining was halted at virtually all major deposits in South Kazakhstan: Mirgalimsai, Achisai, Bayzhansai. The Achpolymetal enterprise is the Kentau’s city-forming enterprise, and the relevance of discovering new commercially significant ore objects in this area is indisputable. The purpose of the work is to investigate the prospects of the southwest of the Greater Karatau ridge for polymetallic mineralization of crust-karst type within the limits of the Ayusai deposit. The object of the study are lithological and stratigraphic irregularities of undivided deposits of the Jurassic and Triassic deposits of Ayusai. The article presents a short review of the results of prospecting and geological surveys and the analysis of the geological and mineralogical assumptions. The results of scientific research suggest the discovery of the crust-karst-type commercial objects with complex lead-zinc-iron-bauxite ores within the study area of highly aluminous deposits with increased lead and zinc content. The results of complex geophysical methods can provide a geophysical basis for further geological exploration of the area, 3D-modelling and calculation of reserves. © 2022, National Academy of Sciences of the Republic of KazakhstanDOI

Практическое значение
The results of integrated geophysical surveys confirmed the prospects of the southwestern Greater Karatau area for the discovery of crust-karst type polymetallic mineralization. The identified target zones can serve as a basis for further exploration activities, 3D geological modeling, and mineral resource estimation. The obtained data contribute to improving the efficiency of mineral exploration and expanding the mineral resource base through the discovery of new lead-zinc, iron, and bauxite ore deposits.Квартиль
