摘　　要：锂辉石是南平稀有金属花岗伟晶岩中的重要标型和造岩矿物。本文论述了它的产状、物理性质、化学成分、Ｘ光粉晶衍射资料、红外光谱和差热分析结果，较详讨论了锂辉石转变成腐锂辉石的过程，最后分析了锂辉石在伟晶岩中的形成条件。he spodumene is an important typomorphic and rock-forming mineral in Nanping rare-metal granitic pegmatites. The paper focuses on the analysis results of the spodumene in Nanping rare-metal granitic pegmatites, such as spodumene occurrence, physical and opical properties, chemical compositions, X-ray diffraction pattern, infrared spectrum and differential thermal curves. Finally, the authors made a discussion on the transformation of spodumene into cymatalite and conditions of forming spodumenes in the pegmatite.
