【摘要】 根据龙水金矿Ⅱ号矿化带的地质特征和不同地质体中微量元素的分布特征、黄铁矿中微量元素的组合特征、稀土元素的分布模式、Ｒｂ－Ｓｒ法确定成矿年龄与锶同位素示踪、铅同位素研究及硫、氧、碳同位素组成的测定结果，论证了龙水金矿赋矿地层以富集Ａｕ、Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ、Ｓｂ、Ａｓ等元素组合为特征；成矿物质可能主要来自花岗岩体，围岩提供了部分成矿物质，有大气降水加入；推测花岗闪长岩的源岩包括古老地壳物质；金矿形成于燕山中期。更多还原

【Abstract】 The paper discusses the geological setting,the distribution of trace elements in various geological bodies,the association of trace elements in pyrites and the REE distribution patterns,as well as the Rb-Sr ore-forming ages,Sr isotopic tracing,Pb,S,O,C isotopic data of the No.2 mineralization zone of Longshui gold deposit.The results show that the host rock contains abundant Au,Ag,Cu,Pb,Zn,Sb and As;the oreforming materials came mainly from granitoids,with some from the wall rock;meteoric water has contributed to the formation of hydrothermal solutions;the source rock of granitoids is ancient crustal materials;and the gold deposit formed during the middle Yanshanian period.更多还原
