摘　　要：地区化学成矿预测可以在不同时间段,同一个位置对有色金属的数据进行对比,但由于不同成矿元素在岩石中的背景值不同,造成预测结果出现偏差,无法准确获取成矿信息。从化学性质上来看,有色金属元素背景值与区域成矿的地化环境和地质环境息息相关。因此,在进行地球化学成矿预测的过程中,需要将有用矿物的主要金属元素转化成元素或其化合物,从而保证预测结果的准确性。Regional chemical metallogenic prediction can compare the data of non-ferrous metals at the same location in different time intervals. However, due to the different background values of different metallogenic elements in rocks, the prediction results are biased and the metallogenic information can not be accurately obtained. In terms of chemical properties, the background values of non-ferrous metals are closely related to the geochemical and geological environments of regional mineralization. Therefore, in the process of geochemical metallogenic prediction, it is necessary to convert the main metal elements of useful minerals into elements or their compounds, so as to ensure the accuracy of prediction results.
