Anbali Gold Deposit is located in the Yangshan gold belt.The main strata outcropping in the mining district are lower Devonian Qiaotou Formation,Xigou Formation,and Minbaogou Formation,all superimposed with later metamorphism.Few magmatic rocks outcrop in the mining district except for granodiorite porphyry,which is closely related to gold mineralization.The surrounding rock alterations are silicification,sericitization,argillization,carbonatization,chloritization,epidotization.Silicification and sericitization are relatively intense close to the ore body;argillization and carbonatization develop more,far from the ore body.By summarizing the geological characteristics of the Anbali Gold Deposit,based on previous research results,the paper analyzed the mineralization and proposed:the Devonian strata with higher background value contribute to the gold source to some extent;the Anchanghe-Guanyinba fault controls mineralization;ore-forming fluids mainly originate from mantle magmatic hydrothermal fluids;silicification takes place during the whole process of mineralization;sericitization mainly takes place before and during mineralization;carbonatization and argillization take place after mineralization.
