东北、山东新生代玄武岩和洋中脊玄武岩的Cd同位素数据（2025）

该数据集包含了东北和山东地区新生代玄武岩和洋中脊玄武岩的Cd同位素数据，为建立新的示踪工具探讨深部碳循环过程提供了重要依据；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；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Cd同位素是示踪深部碳循环的有力工具，能在示踪地幔过渡带的深部碳循环方面有更好的前景。

This dataset contains Cd isotope data of Cenozoic basalts and Mid-Ocean Ridge Basalts (MORB) from Northeast China and Shandong Province, providing critical evidence for establishing new tracer tools to explore deep carbon cycle processes. All data were measured at the Isotope Laboratory of China University of Geosciences (Beijing). For each sample, triplicate measurements were performed, and mass discrimination correction was conducted using the sample-standard bracketing method and internal standard method, with errors reported as 2sd. The dataset is of high quality: the measured values of the international standard reference materials BHVO-2 and BCR-2 agree with the literature recommended values within analytical uncertainties. This dataset demonstrates that Cd isotopes are powerful tracers for deep carbon cycle, and hold great potential for tracing deep carbon cycle in the mantle transition zone.
