Olivine-melt partition coefficients for Mg. As a function of the NBO/T of the melt from experimental data in the Na2O-K2O-CaO-MgO-FeO-Al2O3-SiO2 system (Kushiro and Mysen 2002) coupled with the effect of dissolved H2O on NBO/T (Mysen 2007) of melts to derive effect of dissolved water in melt on the partition coefficient as discussed by Mysen 2012a, b. (A) The K Mg ol-melt data fitted to the equation shown in this figure. (B) Resulting calculated change in Mg partition coefficients as a function of water content.
