| 摘 要： | 川西乡城-稻城-得荣地区，切割深，地貌条件特殊，地表地球化学环境变化复杂，梯度变化小，找矿标志不明显，找矿难度大．运用传统的地球化学数据处理方法，可能漏掉部分异常强度不大而可能成矿的异常，而采用衬值滤波技术便可提取相对弱小的异常信息．在系统总结该区地球化学特征基础上，进行异常筛选与查证，取得较好的找矿效果与经验．

| Abstract: | In the Xiangcheng-Daocheng-Derong area of western Sichuan, geographic conditions are special, dissection is deep, the surface geochemical environment is complicated, and ore marking is not distinctive making it difficult to explore for new deposits. Traditional geochemistry data misses some anomalies that are related to mineralization. The use of contrast filtering methods extracts minor anomalies. A systematic summary of geochemical features in this area, along with filtering and inspection of anomalies, can lead to success. |
