Comparison of source water contents, H2O/Ce ratios and estimated maximum mantle potential temperatures for the sources of komatiites, LIPs and OIBs. a The water content in the sources were calculated from the H2O content of the primary magma (the data source for the komatiite and LIPs are the same as in Fig. 1), assumed degree of partial melting, and the partitioning coefficient of water between mantle rock (peridotite or pyroxenite) and magma. b See the Supplementary file for the details of calculation of H2O/Ce ratios. c All the T p have been corrected for the effect of water, see Methods for the calculation and Supplementary Data 3 for results. The T p range for the Archaean-Proterozoic boundary and the average MORB mantle are from refs. 6, 34,]. All the error bars represent 2 standard deviation. Gorgona komatiite and Tortugal picrite are from Caribbean LIP (CLIP); Siberian AR picrite, the Ayan River picrite, Gd picrite, the Gudchikhinsky picrite; SLC, the pyroxenite xenoliths hosted in the Salt Lake Crater vent, Hawaii, data from ref. 38. The water content and H2O/Ce ratios of the source for Hawaii and other OIBs are from ref. 38 and the literature therein. The T p of Hawaii and other OIBs are from ref. 4, after correction for the effect of water based on ref. 40. CRB Columbia River basalts, SRPB Snake River Plain basalts
