Kangshan Gold Field,part of the north thrust fold zone of Qinling orogenic belt,is located at the intersection of EW Machaoying fault and NE Shanggong-Xingxingyin fault.The ore bodies are in veins and lens,occurring in NE secondary fault.The ores are mainly structural alteration rock type and partly quartz vein type.The alteration most closely related to gold mineralization is silicification,carbonatization,and beresitization.With collection and comprehensive analysis of the ore-forming fluid inclusion and isotopic geochemistry data within Kangshan Gold Field,the study takes that the ore-forming fluids belong to low temperature,low salinity,medium density,CO₂ containing H₂O-NaCl system;the ore-forming materials come from crystallized basement Taihua Group;atmospheric precipitation and magmatic fluid mixing and decreasing temperature are the main reasons for ore materials sedimentation.Based on regional metallogenic features,the metallogenic patterns in Kangshan Gold Field are established.
