东北新生代玄武岩Mg、Zn、Fe、Cu同位素及主微量Sr-Nd同位素数据（2021-2023）

该数据集包含了中国东北地区新生代玄武岩的Mg、Zn同位素Fe、Cu同位素及主微量Sr-Nd同位素数据，为探讨西太平洋俯冲的深部碳循环过程与其引发的效应提供了重要依据；同位素数据来源于中国地质大学（北京）同位素实验室检测，加工方法为每个样品重复测试3次，通过样品-标液间插法以及内标法进行质量歧视矫正，误差以2sd给出，主微量数据来源于中国地质大学（北京）元素地球化学实验室，通过内标法进行矫正；数据质量高，国际标样BHVO-2和BCR-2的测试值均与文献推荐值在误差范围内一致；该数据说明中国东北地区地幔过渡带存在再循环碳酸盐，且这些碳酸盐可以氧化地幔的铁，促进氧逸度的升高和硫化物的溶解，揭示深部碳循环可以促进氧-硫循环。

This dataset contains Mg, Zn, Fe, Cu isotopic data, major and trace element data, as well as Sr-Nd isotopic data for Cenozoic basalts in Northeast China, providing critical evidence for investigating the deep carbon cycle process triggered by Western Pacific subduction and its associated effects. The isotopic data were measured at the Isotope Laboratory of China University of Geosciences (Beijing). Each sample was tested three times repeatedly, and mass discrimination correction was conducted using the sample-standard bracketing method and internal standard method, with errors reported as 2sd. The major and trace element data were acquired from the Element Geochemistry Laboratory of China University of Geosciences (Beijing), and corrections were performed via the internal standard method. The dataset is of high data quality: the measured values of the international reference materials BHVO-2 and BCR-2 are consistent with the literature-recommended values within the error margins. These data demonstrate that recycled carbonates exist in the mantle transition zone beneath Northeast China, and these carbonates can oxidize mantle iron, promoting an increase in oxygen fugacity and the dissolution of sulfides, revealing that deep carbon cycling can facilitate the oxygen-sulfur cycle.
