吉林省东部汪清地区E值综合异常及其找矿意义

E Value Comprehensive Element Anomalies and Prospecting Significance in Wangqing Area in Eastern Part of Jilin Province

E值综合异常是利用地球化学测量数据,直接圈定综合异常的一种方法。汪清地区是典型中生代火山热液型金矿分布的地区,矿化蚀变带规模大,单元素地球化学异常丰值高,具有很好的找矿潜力。为了进一步在该区开展多种成矿金属的普查工作,找寻有价值的异常,对汪清地区1∶50000水系沉积物地球化学测量的元素进行了分析,利用E值综合异常方法,重新圈定出该区的地球化学异常,为进一步找矿提供有利的靶区。

The E value comprehensive anomaly is a method for using the geochemical data and outlining the synthesis anomalies directly.Wangqing area is the typical Mesozoic volcano hydrothermal gold ore distributed area,the scale of mineralization alteration zone is widely,the single element geochemical anomalies value is high,so this area has the benefical prospecting potential.Wangqing area 1∶50 000 stream sediments geochemical survey's data has been analyzed,for carry out prospecting deeply and supply valuable anomalies in this area.Using the method of E value comprehensive anomalies,the geochemical anomalies were outlined in this area again and benefical prospecting targets were supplied and reliable basis for the further prospecting work were put forward.
