Abstract
Purpose. Determination of the features of the formation of gold mineralization within the Bakyrchik ore field and the influence of deep intrusive rocks on the formation of ore bodies. Methodology. Analysis of literature data, interpretation of geophysical studies, field work and laboratory studies on the mineralogical composition of ore bodies and dikes of the Kunush complex (ISP-MS ‒ Agilent 7500cx), study on the main types of mineral associations and zone of alteration (JSM 6390LV)). Findings. Peculiarities of geology, magmatism and ore formation of one of the gold ore deposits of the mesothermal class in the Bakyrchik black shales, located in the West Kalba metallogenic zone (WKMZ) in East Kazakhstan, are considered. Originality. All geological and industrial types of gold mineralization known in the territory of Western Kalba are divided into several levels according to their priority. The most promising, but, despite many years of study, underexplored level is represented by the Bakyrchik ore district. Practical value. The connection of the gold mineralization of the Bakyrchik deposit with zones of tectonically weakened lithosphere and with hidden granitoid intrusions identified by geophysical data is emphasized, which will allow using these data for further exploration within the Western Kalba.
