| 摘 要： | 通过对稀土矿物与碳酸盐相关性,矿物包裹体主要成分,代表性稀土矿物的化学成分,稀土矿物的主要共生、伴生矿物组合,稀土氢化物、稀土合金氢化物的形成条件及理化性质的研究。认为稀土矿床的成矿物质主要是呈稀土合金氢化物与CO、CH4等共同迁移,然后被氧化富集成矿。

| Abstract: | This paper deals with correlation of rare-earth minerals with carbonate facies, major composition of mineral inclusions, chemical composition of individual rare-earth minerals, main coexisting and accompanying minerals of rare-earth minerals, and genetic conditions and physicochemical characteristics of rare-earth hydride and alloy hydride. It is thought that rare-earth deposits resulted from the oxidation and enrichment of the ore-forming substance, in the form of a rare-earth alloy hydride, along with CO2, CH4, and the like, after transported together. |

| Keywords: | rare earth element migrating mode rare-earth alloy hydride genetic mechanism |
