2
O drop of liquid H2O.
-
cMeasured concentration of H2O dissolved in the glass.
-
d
Opx orthopyroxene, Cpx clinopyroxene, Amp amphibole, Glass quenched basaltic glass.
-
eSquare root of an average of phase proportion calculations, modified from Albarède and Provost ([1977]), to account for the addition of F, H2O, and Cl in the starting materials (that diluted the initial element concentrations, see section ‘Equilibrium considerations’ for details). There is a significant uncertainty regarding volatile element initial contents.
- FeO was excluded from mass-balance calculations (FeO loss or gain is assessed after the phase proportions are determined).
-
fDifference between the FeO content of the bulk composition used as starting material in the mass balance (diluted with F and H2O content) and the FeO in the sample bulk composition as determined by mass balance calculation, in relative weight percent. Positive value indicates apparent Fe gain, while negative value indicates apparent Fe loss.
-
gCapsules F contaminated during HF cleaning.
