摘    要：通过对高松山金矿床特征、地球化学特征的分析研究,认为高松山金矿床为浅成低温热液型金矿床,成矿地层是甘河期火山岩,以亚碱性系列之钙碱性高钾火山岩为特征。火山岩稀土元素分析结果表明,该火山岩属轻稀土富集型,铕无明显异常,稀土配分曲线为平缓的右倾。岩石微量元素曲线形态基本相似,表明岩浆具有同源特点。火山岩成因类型为壳-壳幔活动大陆边缘的产物。岩浆演化以分异作用为主,并受一定陆壳混染。

Abstract: Deposit and geochemical characteristic analysis on Gaosongshan gold deposit suggests that it is an epithermal gold deposit. The Ganhe period volcanic rock is the metallogenic formation with the characteristic of subalka- line series,calc-alkaline high-kalium volcanic rocks. REE analysis shows that the rock is characterized by rich LREE,without obvious Eu anomaly. Meanwhile,the REE distribution curves incline gently to the right. The trace elements curves are analogy,which shows the comagmatic characteristic. Volcanic rock genetic types are crust-mantle, the production of active continental margin. The magmatic evolution was mainly of differentiation process with partly continental crust hybrid.
