History
The Zapadno-Palyanskoye field was discovered in 1951 , when V. Kitaev (Chaunskaya GRE) established an increased content of cinnabar in the valley of Brook. Hidden. In 1956, Mamaev A.S. (Chaunskaya State District Administration), by exploration, established the presence of three bodies up to 15 meters thick. Exploration work was carried out from 1956 to 1971.
Geological characteristics
The geological features of the deposit determine the ambiguous interpretation of its genesis - some researchers attribute it to the quartz-dikkit type, and others to the carbonate-polyargillite type. The deposit is confined to the stratum of terrigenous rocks of the Upper Triassic , represented by sandstones , siltstones and shales . Mineralization is localized in three ore deposits — a stockwork deposit in shales with a depth of distribution of 215 m and two lenticular deposits in sandstones. The mineralization age is considered to be Late Cretaceous .
The main industrial ore mineral is cinnabar , observed in the form of streaks, phenocrysts, films, and kidney-like secretions. The average mercury content in the ore is 0.53%.
The balance reserves amount to 10.1 thousand tons [2] .
Perspectives
Given the low world prices for mercury and the constant reduction in its consumption due to toxicity, the operation of the deposit is currently not economically feasible. At the same time, reserves of the West Palyanskoye and neighboring Tamvatneyskoye fields can fully satisfy the needs of the world market for many years [3] .
