Metal-silicate partition coefficient of carbon

This data source information is the summary of chemical composition of the samples published in Kuwahara et al. (2019). Electron microprobe analyzer (EPMA) and Secondary ion-mass spectrometry (SIMS) were used for determining the metal–silicate partition coefficient of carbon from the samples obtained by high-pressure experiments (4–12 GPa). Data 1 summarizes the major composition of metallic and silicate phases of the recovered samples determined by EPMA and EDS analyses. Data 2 shows the hydrogen and carbon contents in silicate of the recovered samples determined by SIMS.
