  1. Mineral abbreviations are given in Fig. 3. Detailed major and trace element compositions of minerals in the starting materials and experimental run products are reported in Tables S6–S11 in Supplementary Data 1. Uncertainty is reported to the last digit(s) in the brackets as the standard deviation of the mean (1σm). ‘n’ denotes the number of analyses.
  2. ab.d. = below detection.
  3. bn.a. = not analysed.
  4. cPartition coefficients are calculated using Eq. (5).
