摘要：
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. © 2021, Science Press.
