摘　　要：根据地球化学测量结果、地质成果资料,将工作区地球化学元素进行R型聚类分析和综合异常圈定评序,按Au—As—Sb成矿元素组合,并圈出五个成矿远景区:柳川吴家院(BHS3)、太白河指甲岩沟—小官庄沟一带(AHS7)、桑园坝玉皇坝(AHS4)三处。Based on stream sediment survey at 1 ： 50, 000 （ 1 ： 25, 000 in key areas of anomaly） and geological profile survey at 1： 5, 000, R-mode cluster analysis of geochemical elements and delineation on the sequence of composed anomalies in the working area have produced the conclusion that the Fengxian-Taibai area of Shaanxi is propitious for mineralization of Au-As-Sb elements, from which five metallogenic potentials have been selected. Three places for gold prospecting in this area are located in Wujiayuan of Liuchuan （ SHS3）, Zhijiagou-Xiaoguanzhuanggou of the Taibaihe River （ AHS7 ） and Sangyuanba-Yuhuangba （AHS4） .
