摘　　要：为查明阿娥作登地区成矿元素和矿(化)体分布特征,在1:1万土壤地球化学测量的基础上,对研究区内6种元素进行聚类分析和因子分析。通过对地表发现的辉铜矿脉进行异常查证,圈定Cu、Ag矿脉3条,铜银矿脉主要发育在火山岩破碎带及裂隙中;研究区具备寻找与火山岩有关的热液型铜银矿的矿找矿潜力。In order to find out the distribution characteristics of ore-forming elements and ore(chemical)bodies in a'ezaodeng area,cluster analysis and factor analysis were carried out on six elements in the study area on the basis of 1:10000 soil geochemical survey.Through abnormal verification of pyroxene veins found on the surface,three Cu and Ag veins are delineated.Copper silver veins are mainly developed in volcanic rock fracture zones and fractures;The study area has the prospecting potential for hydrothermal copper silver deposits related to volcanic rocks.
