摘　　要：对阔尔真阔腊金矿床的成矿温度、微量元素与稀土元素含量、流体包裹体成份、硫、氢、氧、铷、锶等同位素资料的分析对比 ,探讨了该金矿床的成矿作用及其主要过程。认为该金矿床是一产于地洼区的浅成低温热液矿床 ,具有一系列多因复成矿床的基本成矿特征 ,其成矿至少经历了海西期地槽阶段的低温热液富集及中亚期地洼阶段的活化改造这两个重要阶段 ,并建立了其新的成矿模式。By means of analysing and comparing ore-forming temperature,trace elements contents,REE contents,fluid inclusions,sulfur isotopic compositions,hydrogen and oxygen isotopic compositions,and Rb-Sr isotopic compositions for the Kuoerzhenkuola gold deposit,the authors discussed its basic mineralization and mineralizing processes and thought this gold deposit is a typical epithermal deposit formed in a diwa region and has a series of radical metallogenetic featuresfor polygenetic compound ore deposit,and its mineralizing processes had undergone two main stages at least,namely,Hercynian geosyncline stage hydrothermal enrichment and Central Asia Age diwa stage′s activation and reformation.A new mineralizing model has been founded on the basis of above research.
