  1. Analytical uncertainties are indicated in parenthesis with last significant digits (1 standard deviation of analysis). Errors for Pb-isotope compositions represent 2 standard error of the mean. n.d., not determined. No vapor bubble correction was applied on the volatile concentration measurements in the melt.
