喜马拉雅东段库曲岩体中锂、铍和铌钽稀有金属矿物成分数据

此数据集包括锂辉石、锂绿泥石、绿柱石、铌钽氧化物（铌铁矿-钽铁矿、钇铀钽烧绿石、细晶石）的成分分析数据。数据采集自西藏库曲岩体中的电气石花岗岩、白云母花岗岩伟晶岩相、独立含绿柱石伟晶岩脉、以及锂辉石伟晶岩。矿物主量元素数据通过电子探针分析获得，矿物微量元素数据通过激光剥蚀电感耦合等离子体质谱仪分析获得。这些数据提供了喜马拉雅东段首次发现的锂辉石成分，为喜马拉雅东段找锂提供重要证据，通过稀有金属矿物的成分分析，揭示库曲岩体不同期次岩浆活动，加深理解稀有金属成矿过程。This dataset contains compositional analysis data for spodumene, cookeite, beryl, and niobium-tantalum oxide minerals including the columbite-tantalite series, yttrium-uranium-tantalum pyrochlore, and microlite. The data were collected from tourmaline granite, muscovite granite pegmatite facies, independent beryl-bearing pegmatite dikes, and spodumene-bearing pegmatites in the Kuqu pluton, Tibet. Major elemental compositions of the minerals were determined via electron probe microanalysis (EPMA), while trace elemental compositions were acquired using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). These data present the first reported compositional data of spodumene discovered in the eastern Himalaya, providing critical evidence for lithium exploration in this region. Through compositional analysis of rare metal minerals, the dataset reveals multi-stage magmatic activities within the Kuqu pluton, and enhances the understanding of rare metal metallogenic processes.
