华南地区蛇纹石化橄榄岩镍同位素（2024）

华南地区蛇纹石化橄榄岩的镍同位素值，同位素数据标注2SD误差，平均误差为0.02；本研究通过高精度质谱（如MC-ICP-MS）测定镍同位素组成（δ⁶⁰/⁵⁸Ni），结合主微量元素（Cu、Fe、Mn、Zn）分析，计算FeT/Mn、Zn/FeT等比值。采用离子模型计算模拟地幔熔融过程中的平衡分馏效应； 数据应用及前景：轻镍同位素指示高氧逸度、富硫地幔源；重镍同位素（δ⁶⁰/⁵⁸Ni↑）指示贫硫、还原性地幔源

Nickel isotope values of serpentinized peridotites in South China, with isotope data annotated with 2SD errors, and the average error is 0.02. This study determined the nickel isotope composition (δ⁶⁰/⁵⁸Ni) using high-precision mass spectrometry (e.g., MC-ICP-MS), combined with the analysis of major and trace elements (Cu, Fe, Mn, Zn), and calculated ratios including FeT/Mn and Zn/FeT. An ion modeling approach was employed to calculate and simulate the equilibrium fractionation effects during mantle melting processes. Data applications and prospects: Light nickel isotopes indicate high oxygen fugacity and sulfur-rich mantle sources; heavy nickel isotopes (δ⁶⁰/⁵⁸Ni↑) indicate sulfur-poor, reducing mantle sources.
