Comment:
Age correction according to 232Th concentration and a seawater 230Th/232Th ratio of 8±4.
Age correction is negligible within the uncertainties for all data.
Laboratory code/label IUPH: Institute for Environmental Physics, University of Heidelberg, Germany.
d234/238U: measured 234U/238U activity ratios (d234U) are presented as deviation in permil from the equilibrium value.
d234/238Uini.: Decay corrected 234U/238U activity ratios (d234/238Uini.) are calculated from the given ages; decay constants by Cheng et al. (2013) (URI:
All data were calculated using "Th Ghost-signal" correction (Kerber et al. 2023)
Age calculation based on numerically solved equations from Ivanovich and Harmon (1992), age uncertainties are determined using a Monte-Carlo simulation.
