As an important step in geochemical exploration, the analysis of geochemical anomalies is of great significance in the effective discovery of anomalies. Based on the stream sediment data obtained from 1∶200 000 geochemical survey in Xiadong of Beishan area, the authors probed into the feasibility of the application of multi-fractal models to ascertaining the upper limit of the negative anomaly. The result shows that the upper limit of Ba could effectively delineate Ba negative anomaly in the Huitongshan copper deposit.
