摘　　要：以福建邱村金矿矿区地质特征为基础,运用R型因子分析对原生晕样品进行数据处理,从元素异常组合及浓度分带等方面研究了原生晕地球化学特征,发现了As、Sb、Au、Ag、Mo元素代表成矿阶段金矿化元素组合、轴向存在明显且“反分带”现象、680 m至400 m标高存在另一期金矿化等认识。通过邱村金矿原生晕的地球化学特征,结合分析成矿地质背景和矿区的地质特征,认为该矿床属于典型的浅成低温热液型金矿。Based on the geological characteristics of the Qiucun gold deposit in Fujian province,this paper studies the geological characteristics of the primary halo of the Qiucun gold deposit from the ore-forming elements,zonation of primary halo,and the feature of axial zoning by analyzing the data with the R-mode factor analysis method.The discovered As,Sb,Au,Ag and Mo elements represent the combination of gold mineralization elements in the metallogenic stage.The primary halo axial zoning features and“reverse zoning”features are obvious.The next developed location of ore body concentrates in the range of 680~400 m middle section.Based on the analysis of the geochemical characteristics of the primary halo of Qiucun gold deposit,combined with the metallogenic geological background and geological characteristics,it is considered that the deposit is a typical epithermal type.
