| 摘 要： | 通过对金顶矿床稀土元素的分析,显示稀土总量较低,具有轻稀土比较富集、轻重稀土元素具中等分馏的特征。铕(Eu)在铅锌金属矿物和石膏中比较亏损(δEu=0.06~0.76),表现出负异常;而在褐铁矿、天青石中铕(Eu)比较富集(δEu=0.76~14.95),表现出正异常;表明褐铁矿、天青石与其它铅锌矿物不是同一期的产物;暗示金顶铅锌矿床在沉积之后经受了后期热液的改造叠加成矿作用。这对矿床成因研究及勘查具有一定的参考意义。

| Abstract: | Through analysis of rare earth elements （REE）in Jinding deposit,it is suggested that the total REE content is relatively low,and is characterized by enrichment of light rare earth and medium fractional distillation of light and heavy rare earth elements.Eu in Pb-Zn ores and gypsum is relatively depleted （δEu=0.06~0.76）and shows negative anomaly;Eu in limonite and celestite is relatively enriched （δEu=0.76 ~14.95）and shows positive anomaly.Hence,it is shown that limonite and celestite is products of a different age from Pb-Zn ores,and it is implied that Jinding Pb-Zn deposit suffers from superimposition reformation of late-stage hydrothermal solution after sedimentation.This article provides a reference for deposit genesis re-search and survey. |
