摘　　要：河南熊耳山地区是豫西重要的金矿化集中区,萑香洼金矿是该成矿带近几年新发现的金矿床。通过运用地球化学成矿指数、聚类分析和因子分析的理论与方法,解析了萑香洼金矿的地球化学场,得出如下主要研究成果:①金矿床F985矿脉呈现以Au、Ag为主,伴有Pb、Zn、Cu、Bi、As、Sb等多元素的综合原生晕;②厘定金矿床的地球化学原生晕的轴向分带、横向分带和纵向分带;③原生晕轴向分带序列:头晕元素组合为As、Sb、Ba,主成矿晕元素组合为Au、Ag、Pb、Zn、Cu、Mo,尾晕元素组合为Co、Ni、Bi;④依据综合原生晕异常套合的特征,优选了4个找矿靶区,对深部隐伏矿体进行定位预测。Xiong＇ershan belt is an important concentration area of gold mineralization in the western Henan, Huanxiangwa gold deposit was found in recent years in this metallogenic belt. Based on studies of theories and methods of ore - bearing index, factor analysis and cluster analysis, structures of gem, heroical fields in the Huanxiangwa gold deposit has been resolved and the following research achievements have been obtained. （ 1 ） There are cornpound primary halos of multiple elements, mainly Au and Ag, with Pb ,Zn ,Cu, Bi ,As and Sb in the Vein F985 of Huanxiangwa gold deposit; （2） Axial, lateral and longitudinal zonations of indictor dements in geochemical primary halo have been ascertained; （3） Axial zoning sequence of primary halo can be classified as follows ： the head halo is As - Sb - （ Ba）. main ore - forming halo is Au - Ag - Pb - Zn Cu - Mo, and trail halo is Co - Ni - Bi ; （4） Based on the synthetically research in ore - forming element abnormality, four target districts were elected, and concealed gold orebodies were prognosticated.
