REE features of quartz and pyrite and their fluid inclusions: an example of Jiaojia-type gold deposits, northwestern Jiaodong peninsula.

  • 本文采用ICP—MS测定了焦家、马塘、东季、红布等焦家式金矿床中黄铁矿、石英及其包裹体的稀土元素组成。结果表明:采用ICP—MS直接测定黄铁矿包裹体的稀土元素是可行的;包裹体爆裂丰度虽然对稀土总量有影响,但矿源稀土元素背景值的差异也是流体中稀土总量差别的主要原因之一。∑REE、δEu、δCe及LREE/HREE、(La/Yb)N、(Ce/Yb)N、(La/Lu)N都是有意义的稀土元素特征参数;焦家式金矿同一成矿阶段黄铁矿、石英及其包裹体的稀土元素特征相似,显示了它们的同源特征;不同成矿阶段黄铁矿、石英及其包裹体的稀土元素特征有差异,反映了其成矿流体特征的差异。
