Based on these, The enrichment mode of the geochemical elements and their distribution in space are discussed and the anomaly lower limit can be obtained and then the geochemical backgrounds、regional anomalies and local anomalies are distinguished.

在此基础上，分析了元素的成矿富集规律和空间分布特征，确定了区域异常和局部异常的异常下限，划分了地球化学背景、区域异常和局部异常。
