Elevated silicon content facilitates carbon precipitation within Mercury’s core - Electron Microprobe Analysis Data

This Excel sheet contains EPMA compositional analyses of the quenched Fe-Si-C metallic liquid from our multi-anvil experiments, reported by run/sample and analysis point. Each row corresponds to an individual EPMA spot (or an averaged set, if noted) and includes the measured element concentrations (Fe, Si, C), totals, and any identifiers needed to link analyses to a specific run condition. The data show that dissolved carbon in the metal decreases systematically with increasing Si, consistent with carbon-saturated liquids coexisting with graphite/diamond in many runs.

本Excel表格收录了本团队多砧实验中淬火得到的铁-硅-碳（Fe-Si-C）金属熔体的电子探针显微分析（EPMA）成分数据，按实验批次/样品及分析点位进行整理。表格内每一行对应单个EPMA测点（若有标注则为一组平均测点），包含实测的铁、硅、碳元素浓度、总含量，以及用于将分析结果关联至特定实验批次条件的全部标识信息。数据表明，金属熔体中的溶解碳随硅含量升高呈系统性降低，这与多数实验批次中碳饱和熔体与石墨/金刚石共存的现象一致。
