| 摘 要： | 与火山、次火山隐爆作用有关的中酸性隐爆角砾岩型矿床是一种重要的矿床类型.中酸性隐爆角砾岩型金、银-金、铀、钨-钼-铜-铅-锌典型矿床的矿石、蚀变围岩稀土元素研究表明,不同矿种的矿床稀土元素地球化学具有极强的相似性和弱差异性.矿床稀土元素总量w(REE)=69.7×10-6～245.27×10-6,单个矿床稀土元素总量变...

| Abstract: | The volcanism and sub-volcanism-related intermediate-acid cryptoexplosive breccia type metal deposit is an important ore deposit including Au,Ag-Au,U,W-Mo-Cu-Pb-Zn ore deposits.Researches on ore and wall rock alteration of the type show strong similarity and less discrepancy for their REE geochemistry characterized by total REE in range 69.7×10-6 to 245.27×10-6 and less variation of the range for each deposit,right-inclined REE pattern,LREE/HREE in range 3.31 to 14.5,and concentration betwem 3.31 to 9.52 and 7.3 to 14.5 and strong Eu negative to weak anomaly or non-anomaly. |
