Abstract: In some course of studying the regional geochemica1 anomalies within the area of metallogenetic zones or a province, incorrect messages are often being found that there are some anomalies without mineral deposit or some mineral deposits without geochemica1 anomaly. This situation makes it difficult to evaluate geochemical anomalies. Using the information coming from practice, this paper analyses the causes of making this matter and introduces several means used to solve this problem by comparing, meanwhile,recommend ano ther method named "gliding average standardization data method".And full details of theoretical base,its superiority and the using result of the method are given.
