ENDOGENOUS MINERALIZATION OF THE CENTRAL BUKANTAU AREA (USING THE EXAMPLE OF THE KYZYLKUM REGION)

The article investigates the mineral composition of the oxidized ores developed in the Kaskirtov, Boztov and Zhelsay promising fields in the north-western part of the Central Bukantov, as well as their formation characteristics and productive mineral associations are determined. According to the obtained results, the main ore minerals consist of iron hydroxide (goethite, hydrogethite), jarosite, scorodite, and pure gold, which are located in the limonited parts of shale and metasiltstones, which are the host rocks. It was found that the oxidized ores were formed under the influence of hypergenic solutions and formed mineral associations with gold-jarosite-hydrolyte in the lower part of the oxidation zone, and gold-hydrogoethite-kaolinite in the upper part.
