Figure 3. Example of AVF CO2 (dashed red line) and S (solid orange line) open-system degassing curves. These EVo-produced results are based on Rangitoto - Motutapu Is. geochemical data. Fraction of initial CO2 and S concentration left in the melt is shown at each pressure step (with approximate depths on secondary y-axis, based on a 0.037 km/MPa geostatic gradient). The bottom of the crust under Auckland is at 27.5 ± 2.5 km.Figure 3 in the journal article entitled, Estimating Eruptive Volatile Emissions and Fluxes in the Auckland Volcanic Field, Aotearoa New Zealand, submitted to the Journal of Applied Volcanology. Part of Elaine Smid's PhD thesis at the University of Auckland.
