Ore potential prospects based on mineralogical data of the West Yangi-Umid site (Uzbekistan)

The relevance of this article lies in the assessment of the prospects for ore-bearing mineral composition of ores, its diversity in the West Yangi-Umid area. The subject of the research is ore minerals, stages of hypogene mineral formation. In the process of research, we used geological documentation of ore-bearing and mineralized zones, sampling, sample preparation for chemical and geochemical analysis, description of thin and polished sections, mineralogical analysis of gravity enrichment products, X-ray spectral microprobe studies, identification of vertical zoning of mineralization, a scheme of the stages of hypogene mineral formation based on mineragraphic data. As a result of research, 26 ore minerals in the Western Yangi-Umid area were identified. A wide range of mineral formation — from the early oxide stage with magnetite-hematite PMA to quartz-calcite-barite-fluorite carbonate-fluoride stage indicates the prospects of the Western Yangi-Umid site. Among them, the pyrite-arsenopyrite with gold PMA of the early sulphide stage and gold-silver PMA of the same stage are productive for gold.
