腾冲保山地块中生代沉积岩主微量，锆石U-Pb同位素数据集

此数据集包括云南腾冲保山地块中生代沉积岩主微量元素和锆石U-Pb同位素数据。采样时间为2018年，地区为云南腾冲保山地区的腊勐镇附近，岩石样品包括8件沉积岩样品。该数据为认识腾冲保山之间中特提斯构造演化提供关键信息，将中特提斯洋的闭合时间限制在晚侏罗世，对探讨特提斯构造演化过程具有重要意义。岩石样品的全岩主、微量元素分别使用荧光光谱仪（XRF）和等离子质谱仪（ICP-MS）测试，锆石U-Pb定年使用激光剥蚀等离子质谱仪（LA-ICP-MS），测试单位包括中科院地质与地球物理研究所和青藏高原研究所。该数据集关联文章已发表在刊物《Journal of Asian Earth Sciences》上，数据结果真实可靠。

This dataset comprises major and trace element data of Mesozoic sedimentary rocks and zircon U-Pb isotopic data from the Tengchong-Baoshan block in Yunnan Province, China. Sampling was conducted in 2018 near Lameng Town, Tengchong-Baoshan area, Yunnan Province, with a total of 8 sedimentary rock samples collected. This dataset provides critical insights into the tectonic evolution of the Tengchong-Baoshan region, constraining the closure time of the Central Tethys Ocean to the Late Jurassic, which is of great significance for investigating the Tethyan tectonic evolution process. Whole-rock major and trace elements of the samples were analyzed using X-ray Fluorescence (XRF) spectrometer and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) respectively, while zircon U-Pb dating was performed via Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The analytical tests were completed by the Institute of Geology and Geophysics and the Institute of Tibetan Plateau Research, Chinese Academy of Sciences. The associated research article of this dataset has been published in the journal *Journal of Asian Earth Sciences*, and the data results are authentic and reliable.
