| description | The described research is now becoming even more relevant due to the efficiency improvement of expected gold ore exploration based on sophisticated geochemical information processing and interpretation methods. The main aim of the study is to investigate geochemical zoning and to identify anomalous geochemical deposit structure within Zapadnoe gold ore deposit for working out addition search criteria to predict gold objects. The methods used in the study: statistic parameter calculation by nonparametric mathematical statistic method and their further pro cessing through software programs Surfer, Statistica, Corel Draw; semiquantative emission spectral analysis; assay testing. The results: The authors have studied geochemical zoning of Zapadnoe deposit based on core sampling results from five well exploratory lines. It was ascertained that anomalous structure of geochemical Zapadnoe deposit is of concentric zonal structure. The central area (As-Au) and mineralized periphery (Pb-Zn-Cu-Au и Co-Ni) are contoured by contrasting geochemical haloes of ore-element associations. The identified geochemical associations and their spatial position correlate to mineral formation staging developed for Sukholozhskoe ore deposit. Based on interpretation of deposit geochemical field abnormal structure the authors detected mineralized zone boundaries, selected mineral and geochemical associations of ore formation. The data obtained allowed defining more precisely the structure of bulk geochemical Zapadnoe deposit halo. |
