Abstract: With the 1:50000 high-accuracy ground magnetic prospecting, the authors analyze the distributing features of local magnetic anomaly in the survey area and regional magnetic anomaly, summarize the magnetic field features of major geological units, delineate 14 magnetic anomalies and interpret 16 fault structures and 7 volcanic conduits. Combining with the geological conditions, the article comprehensively interprets the 14 magnetic anomalies and infers that C1, C2 and C13 magnetic anomalies are favorable targets for polymetallic ore prospecting. The C4, C9, C10, C12 and C14 magnetic anomalies have good geological conditions for formation of polymetallic ores.
