A melt model that calculates the solubility of water according to parameterized phase diagrams for four lithologies: 1) sediment 2) mid-ocean ridge basalt (MORB) 3) gabbro 4) peridotite from Tian, 2019 https://doi.org/10.1029/2019GC008488.
These functions can be used in the calculation of reactive fluid transport of water.

The following coefficients are taken from a publication from Tian et al., 2019, and can be found in Table 3 (Gabbro), Table B1 (MORB), Table B2 (Sediments) and Table B3 (peridotite). LR refers to the effective enthalpy change for devolatilization reactions, csat is the saturated mass fraction of water in the solid, and Td is the onset temperature of devolatilization for water.

The polynomials breakdown above certain pressures, 10 GPa for peridotite, 26 GPa for gabbro, 16 GPa for MORB, and 50 GPa for sediment. These cutoff pressures were determined by extending the pressure range in Tian et al. (2019) and observing where the maximum allowed water contents jump towards infinite values.
