Extended Data Table 4 Trace element composition of the metasomatic C-rich melts

From: Carbon concentration increases with depth of melting in Earth’s upper mantle

  1. Inferred trace element composition (in mg/kg) of the metasomatic C-rich melts (mCm), derived by applying non-linear least-squares regression to gas vs. trace-element populations (example in Extended Data Fig. 6). *CO2 (in wt.%), S and Sr (in mg/kg) concentrations are independently fixed based on the composition of natural kimberlitic and carbonatitic rocks and/or experimental melts formed during mantle rock melting expertiments4,5,6. See text for further explanation.
