Comment:

The data set includes the geographic position and elevation of the analyzed samples and the obtained zircon (U-Th)/He ages. Ejection correction (Ft): correction factor for alpha-ejection (according to Farley et al. (1996) and Hourigan et al. (2005)). Uncertainty of the single-grain ages includes both the analytical uncertainty and the estimated uncertainty of the ejection correction. Sample age (2se standard error) is the unweighted average age of all Ft-corrected (U-Th)/He ages. Results from aliquots written in italics are not considered in the calculation of the sample age.
