摘　　要：蓬勃山地区位于天山—阴山构造带东段,隶属于甜水井—乌珠尔嘎顺—雅干成矿带。研究区矿化主要表现为金矿化,矿化类型较为单一。通过对研究区的土壤地球化学测量,共圈出单元素异常66处。根据各元素聚类分析结果,并结合元素异常的套合情况,进一步圈定了4处组合异常。综合考虑研究区土壤地球化学异常特征、土壤地球化学组合异常所在位置及异常与地质体、矿脉的关系,在研究区内圈定了三个找矿靶区并进行了工程验证,取得了良好的找矿效果。Pengboshan area locates in the eastern Tianshan-Yinshan structural belt,belonging to the Tianshuijing--Wuzhuergashun--Yagan metallogenic belt. The gold mineralization in the area is strong and single in type.66 uni-element abnormities was delineated on the basis of the soil geochemistry survey data of the studied area. 4multi-element anomaly was delineated in accordance with the results of the clustering analysis of each element and the overlap situation among multi-element anomalies. Considering the characters of soil geochemistry anomaly,locations of soil geochemical assemblage anomalies and relationship of anomaly with geological bodies and ore-veins,we have delineated and verified 3 prospecting target zones and have achieved an excellent ore prospecting effect.
