  1. aFrom Johnson et al. ([1990]).
  2. bFrom Hauri et al. ([2006]), we used average value of D F and D Cl between olivine and basaltic melt.
  3. D o bulk = Σ D i mineral/melt · X i mineral, where X is the proportion of mineral in the anhydrous lherzolite and D i mineral/melt are presented Table 5.
  4. P i bulk = Σ D i mineral /melt · p i mineral, where p are the stoichiometric coefficients of melting (see text).
  5. D i bulk = [D o bulk − (P i bulk · χ)]/(1 − χ), where χ is the degree of melting.
