| 摘 要： | 通过扫描电镜和电子探针在赛马铌钽矿床识别出独立铌钽矿物,种类主要为铈铌钙钛矿、钙铌矿及铌钛铀矿. 该发现回答了对辽东地区是否存在独立铌钽矿物的质疑. 根据全岩Sr-Nd-Pd同位素分析结果推断该铌钽矿床的成矿过程与富集地幔有关,同时有部分地壳物质的混入.

| Abstract: | Through scanning electron microscopy and electron probe, independent niobium-tantalum minerals, mainly loparite, betafite and fersmite, are identified from the Saima Nb-Ta deposit in eastern Liaoning Province for the first time. The discovery solves the controversy about the existence of independent niobium-tantalum minerals in the area. According to the results of Sr-Nd-Pd isotope analysis, it is inferred that the mineralization of the niobium-tantalum deposit is related to mantle enrichment, with mixture of some crustal materials. |
