安门弄勒矿化区岩浆岩锆石U-Pb谐和图年龄数据集

本数据集包括安门弄勒岩浆岩LA-ICP-MS锆石U-Pb年龄数据，限定了安门弄勒成岩时代。研究结果表明了安门弄勒矿化区成岩时代在120Ma左右，属于早白垩世岩浆活动的产物。锆石U-Pb定年在中国地质科学院矿产资源研究所所属的自然资源部成矿作用与资源评价重点实验室使用激光剥蚀-电感耦合等离子体质谱仪（Thermo Fisher的ElementXR）完成。采用的激光剥蚀系统为RESOlution S-155型193nm准分子激光。This dataset contains LA-ICP-MS zircon U-Pb age data of the Anmenlongle magmatic rocks, which constrains the diagenetic age of the Anmenlongle area. Research results indicate that the diagenetic age of the Anmenlongle mineralization zone is approximately 120 Ma, which is the product of Early Cretaceous magmatic activity. The zircon U-Pb dating was completed at the Key Laboratory of Metallogeny and Mineral Resource Assessment, Ministry of Natural Resources, affiliated to the Institute of Mineral Resources, Chinese Academy of Geological Sciences, using a laser ablation-inductively coupled plasma mass spectrometer (Thermo Fisher ElementXR). The adopted laser ablation system is the RESOlution S-155 193 nm excimer laser.
