Table 1 Arrhenius fit parameters for the temperature variations of different species diffusivities and viscosity at zero pressure (±1 GPa) of the carbonated MgSiO3 melt (with 16.1 wt % CO2).

The model parameters for the pure melt (40, 44) are shown for comparison. Dα represents the self-diffusion coefficient for species α (Mg, Si, O, and C) and η represents the melt viscosity.
