| 摘 要： | 矿床含矿岩系下石炭统依柳组(C1y)火山岩系形成于陆内裂谷构造环境,具有大陆碱性玄武岩特征。岩系中成矿元素铅、锌(特别是铅)背景值较高,为区内银铅锌多金属矿重要矿源层;岩系因子分析表征:Cu、Pb、Zn、As、Sb、Sn、Ag、Au等元素与Cu、Bi、Sn、Mo、Se、W等元素均代表不同期次成矿作用和主要成矿元素组合,对指导区带成矿环境与成矿作用具有一定理论意义。

| Abstract: | The ore-bearing rock series of Ag-Pb-Zn multimetallic deposit in Lancang is the Lower Carboniferous Yiliu Formation（C1y） volcanic rock series,which is formed in the continental rift tectonic environment and has the characteristics of continental alkaline basalt.The background of metallogenetic elements Pb,Zn（especially Pb） in the ore-bearing rock series is high,which is the important ore source bed of the Ag-Pb-Zn multimetallic deposit in this area.According to the factor analysis of ore-bearing rock series,Cu,Pb,Zn,As,Sb,Sn,Ag,Au,etc,and Cu,Bi,Sn,Mo,Se,W,etc represent the different stage metallogenesis and the assemblage of main metallogenetic element,which have a certain theoretical significance in the direction of regional metallogenetic environment and metallogenesis function. |
