部分国际标样和国内标样的Mg同位素数据

该数据由中国地质大学（武汉）地质过程与成矿预测全国重点实验室分析完成。实验流程为：将样品研磨成粉末后经化学纯化处理，随后使用多接收电感耦合等离子体质谱仪（MC-ICP-MS）进行数据采集，每个样品重复测试6-10次。采用样品-标液间插法和内标法进行质量歧视校正，误差以2SD表示。实验结果为国际地质样品Mg同位素研究提供了有效参考值，其中多个参考物质的测定值为首次报道，为实际地质样品的Mg同位素数据分析提供了重要依据。

This dataset was analyzed and completed by the State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences (Wuhan). The experimental procedure is as follows: Samples were ground into powder and subjected to chemical purification treatment, followed by data collection using a multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS). Each sample was repeatedly tested 6 to 10 times. Mass discrimination correction was performed using the sample-standard bracketing method and internal standard method, with errors reported as 2SD. The experimental results provide effective reference values for international geological sample Mg isotope research. The measured values of multiple reference materials are reported for the first time, providing an important basis for Mg isotope data analysis of actual geological samples.
