Abstract
The article presents the results of mineralogical, petrographic, and geochemical studies of hydrothermally altered and metamorphic formations of the Olympiada deposit. It shows that the combination of beresitization-sericitization aureoles, which control the distribution of stratiform gold–sulfide mineralization in space with multiplicative positive geochemical anomalies of AuAsTeSbHg composition close to them in morphology, can be used as hydrothermal alteration and geochemical criteria for predicting gold–sulfide mineralization in the Olympiada ore field. The geological and genetic model of the formation of the Olympiada ore deposit is discussed, and recommendations on the use of this model for prospecting purposes are given.
期刊介绍:
Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
