This is an article in the field of earth sciences.Based on the 1∶25000 trench soil geochemical survey carried out in the Yongxi gold polymetallic mining area in Danba County,this paper reveals the element geochemical characteristics and anomaly distribution laws represented by gold,silver,arsenic and antimony in this area,finds a number of valuable geochemical comprehensive anomalies,analyzes the prospecting potential of geochemical anomaly areas,further narrows the prospecting scope,and delimits a prospecting target area.The engineering verification of the target area has achieved good prospecting results,which proves that the trench soil geochemical survey method is effective in the geological exploration work in this area,and provides a scientific basis for further geological work.
