摘　　要：为西昆仑乔尔天山—岔路口铅锌富集带取得找铅锌新突破,以该区1∶50万水系沉积物测量成果为基础,部署1∶5万化探普查项目,根据化探异常,筛选出以Pb为主的HS-10和HS-27综合异常,结合景观地球化学特征进行1∶1万土壤测量,通过分析主要成矿元素地球化学特征,推断铅矿化体空间赋存位置,经系统地表和深部工程验证,发现甜水海铅锌矿和天柱山铅锌矿。甜水海地区找矿实践证明,重视区域化探异常筛选,逐步聚焦异常查证,选择最佳成矿有利部位进行地质调查和工程揭露,能有效提高找矿效率,缩短勘查周期。To make new breakthrough in lead-zinc exploration in the Qiao＇er Tianshan-Chalukou lead and zinc ore concentration area of the Western Kunlun Mountains, the authors arranged 1 ？ 50 000 survey project of geochemical exploration based on the results of 1 ？ 500 000 stream sediment survey, and picked out the integrated anomalies of HS-10 and HS-27 which are mainly composed of Pb ac-cording to the anomalies delineated in 1 ？ 50 000 geochemical exploration. Then, together with the geochemical characteristics of the landscape and the results of 1 ？ 10 000 soil sur^^ey as well as the analysis of the geochemical characteristics of the main ore-for^ning ele-ments, the distribution positions of lead orebodies were estimated. At last, according to the exterior and deep engineering verification, the Tianshuihai lead-zinc deposit and the Tianzhushan lead-zinc deposit were found. The experience gained from prospecting work in Tianshuihai area indicates that the means put forward by the authors will effectively improve the prospecting rate and shorten the period of exploration by paying attention to picking out regional geochemical anomalies, focusing on abnor^mity-testing step by step, and selec-ting the most favorable ore-for^ming position for geological sur^^ey and engineering revealing.
