Figure 2

Graphical summary of zircon double dating results: Left panel—ranked order plot of alpha ejection and disequilibrium corrected zircon (U–Th)/He dates displayed as 2σ error bars. Weighted mean (solid black line) and 95% confidence interval (dashed black lines) represent our best ZDD estimate for the time of eruption and its uncertainty (or ZDD eruption age). Right panel—ranked order plot of zircon U–Th ages with 1σ analytical uncertainties. Deep yellow bar indicates the 95% confidence interval of the ZDD eruption age. Note that U–Th ages provide maximum eruption age and the youngest U–Th ages overlap within uncertainty with the ZDD eruption age, providing additional confidence in the data.
