| 摘 要： | 稀有金属伟晶岩主要分为LCT (Li-Cs-Ta)型和NYF (Nb-Y-F)型,其中LCT型伟晶岩是全球重要锂矿来源.本文分析了全球伟晶岩型锂矿床的地质勘查和研究成果,简要介绍了各大陆代表性伟晶岩型锂矿床,发现锂矿空间分布不均匀,成矿时间具有多期性和阶段性,成矿事件主要发生在汇聚造山作用的晚期,伴随超大陆汇聚事件.LCT型伟晶岩富含挥发分,与后碰撞S型花岗岩密切相关,多产于中高级变质岩区,就位深度较大,多沿断裂构造贯入.

| Abstract: | The pegmatites containing rare metals are classified into LCT (Lithium Cesium Tantalum) and NYF (Niobium Yttrium Fluorine) types, with the LCT type being the world''s most important source of lithium. In this contribution we review the global progress in geological exploration and study of the pegmatite type lithium deposits, and briefly introduce representative deposits from different continents. It is noted that the pegmatite type lithium deposits are heterogeneous spatial distribution. Temporally, the mineralization shows multistage and episodic features. Most of the LCT type pegmatites were formed during late stage of the convergent orogenies, and possibly associated with the supercontinent assembly. The LCT pegmatites are generally enriched in volatile components, genetically related to post collisional S type granites, spatially hosted in metamorphic rocks, and deeply seated along fault structures. |
