Abstract

The article presents a study on the geochemical characteristics of the ore deposits in the Bakyrchik ore area (Bakyrchik, Glubokiy Log, Zagadka, Promezhutochnoe), which is located in the Zharminsk district of the Abay region in Eastern Kazakhstan.The aim of the study is to identify and describe the geochemical characteristics of the ore deposits in the Bakyrchik ore field, and to analyze the distribution and zonation of elements within ore bodies and areas of dispersed mineralization. The results of spectral analysis on 30 rock samples collected from various depths (550–700 meters) in the vertical mineralization profile of the Bakyrchik field. Samples were taken from core material from different wells in different areas of the field, including Bakyrchik, Glubokiy Log, Zagadka, and Promezhutochnoe, as well as from zones of ore bodies and other areas such as zones of fracture, mylonite, calcite, and sulfide mineralization, considering lithological features. Based on the results of geochemical studies conducted, the characteristics and differences in geochemical properties of large and small ore deposits have been identified, and the distribution of chemical elements within zones of dispersed mineralization has been described. The practical significance of this work lies in the fact that the revealed patterns of element distribution and geochemical zoning to predict the presence of new ore deposits, interpret chemical anomalies, estimate the level of erosion of mineralization, and optimize exploration and assessment efforts in other areas within the ore field.
