Notes. (*) Element abundances based on BSE abundances, but altered by the addition of H2O, see Sect. 2.3. (†) The PWD data is completed by taking the missing element abundances from BSE, MORB, or CI as indicated. (∇) The element abundances are created by a fit to Earth atmospheric concentrations, see Appendix A.
