Localization conditions of apometaterrigenous non-carbon the Sarykul deposit of the Karatyubinsky ore district in Uzbekistan

Abstract

This article explores the occurrence of apometaterrigenous non-carbon tungsten mineralization at the Sarykul deposit in the Karatyubinsk Mountains. Initially considered unpromising, this newly discovered tungsten mineralization was found during gold mining operations. The prospecting activities targeting calcification zones in metaterrigenous rocks revealed their tungsten-bearing nature. This discovery has reshaped the understanding of tungsten mineralization genesis, lithological and structural conditions, and the overall minerogenic potential of the Karatyubinsky ore field.Apometaterrigenous tungsten mineralization originates from coarse flysch rocks transformed into shale rocks in the contact zone with a tungsten-specialized granitoid intrusive. The mineralization is associated with multicomponent metasomatites formed on aluminosilicate metaterrigenous rocks. Significant correlations exist between tungsten and elements such as Pb, Ag, Au, Be, Cu, Mo, V, and Mn. Scheelite mineralization forms autonomously, followed by the combination of different stages within mineralized zones. The regional trog structure, characterized by the formation of an olistostromic stratum due to high granulometric dispersion, is also linked to the apometaterrigenous mineralization.
