*Activity ratios determined after Hellstrom (2003).

^{†}Age in kyr BP corrected for initial^{230}Th using equation (1) of Hellstrom (2006), the decay constants of Cheng*et al.*(2013) and a [^{230}Th/^{232}Th]_{i}value of 1.5 ± 1.5.^{‡}Initial [^{234}U/^{238}U] ratios calculated using corrected-age 2 sigma uncertainties in brackets are of the last two significant figures presented.
