U/Th dating results of sediment core GeoB23225-1

DOI

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: https://doi.org/10.1016/j.epsl.2013.04.006). 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.
