| 摘 要： | 利用扫描电镜－能谱对四川冕宁稀土矿床早期萤石的单个流体－熔融包裹体的成分进行了分析，发现包裹体内流体相离子以Ｎａ、Ｃａ、Ｂａ为主，阴离子以ＳＯ４、Ｆ、Ｃｌ米，有意义的是在包裹体中发现了Ｌａ、Ｃｅ、Ｎｄ等稀土元素，其中矿化元素素铈的含量最高，研究结果进一步证明四川冕宁稀土矿床是一个与盐熔体有关的热液矿床。

| Abstract: | Scanning electron microscopy combined with energy dispersive analysis has been used to detect the composition of single fluid melt inclusion in fluorite formed in early stage Mianning REE deposit of Sichuan, China, The energy dispersive spectra show that the cations are dominated by Na, Ca, K, Ba, and anions by SO 4, F, Cl. Significantly, high contents of LREEs, La, Ce, Nd have been observed in the fluid inclusion, of which the content of the ore forming element Ce is the highest. These results further prove that the Mianning REE deposit in Sichuan is a hydrothermal deposit genetically related to salt melt. |
