Mineral/melt partition coefficients of fluorine (A) and chlorine (B) versus NBO/T, (C) $\mathbf{RTln}\left({\mathit{D}}_{\mathbf{F}}^{\mathbf{mineral}/\mathbf{melt}}\right)$ versus NBO/T and (D). $\mathit{RTln}\left({\mathit{D}}_{\mathrm{C}\mathrm{l}}^{\mathrm{mineral}/\mathrm{melt}}\right)$ versus NBO/T, where R is the gas constant and T the temperature in K. Here $\mathrm{RTln}\left({\mathit{D}}_{\mathrm{volatile}}^{\mathrm{mineral}/\mathrm{melt}}\right)$ is equal to ∆G, the free Gibbs energy; NBO/T were calculated following the procedure in Mysen and Richet ([2005], Chapter 4) as explained in the text. Data from this study are compared with literature data for olivine (Hauri et al. [2006]; Beyer et al. [2012]), orthopyroxene (Hauri et al. [2006]; Beyer et al. [2012]; Dalou et al. [2012]), and clinopyroxene (Hauri et al. [2006]; O’Leary et al. [2010]; Dalou et al. [2012]).
