Major and trace elements and Nd isotopic compositions of apatite grains from pegmatites in the Ke'eryin field, eastern Tibetan Plateau

We report the major and trace elements and Nd isotopic compositions of apatite grains from the Triassic Li-mineralized and barren pegmatites in the Songpan-Ganzi orogen, eastern Tibetan Plateau. The major elements of apatite grains were measured using Electron Microprobe (EMP) at the Hefei University of Technology. The trace elements and Nd isotopic compositions of apatite grains were measured using Inductively Coupled Plasma Mass Spectrometry Laser Ablation (ICP: MS-LA) and Inductively Coupled Plasma Mass Spectrometry Laser Ablation Multicollector (ICP:MS-LA-MC), respectively. at the Wuhan Sample Solution Analytical Technology Co., Ltd., Wuhan, China. The apatite grains from mineralized and barren pegmatites have contrasting MnO, REE, Th and Li concentrations and REE patterns. These data are used to explore how melts that formed the mineralized and barren pegmatites evolved differently. This dataset is a supplementary for the manuscript (ID JPET-Jun-24-0119) submitted to Journal of Petrology.
