Abstract In the appraisal of geochemical anomalies, the distinction between the anomaly related to mineralization and the barren anomaly and the determination of major ore-forming elements constitute the major problem that geochemical researchers have to face. The existence of the composite anomaly composed of more than ten elements makes the problem more complex. The adoption of the "contrast anomaly amount" parameter can quite simply help determine the major metallogenic elements and evaluate the anomaly so as to guide the ore-prospecting work. The practical application of this method to lead-zinc ore exploration in Liupan Mountain area shows that the determination of major elements in both regional geochemical anomaly and ore district anomaly is consistent with the drilling result. It is therefore held that this method is helpful to the determination of major elements in geochemical anomalies and hence deserves popularization.
