Comment:
U decay constants: λ238=1.55125x10-10 (Jaffey et al., 1971) and λ234= 2.82x10-6 (Cheng et al., 2013).
Th decay constant: λ230=9.1705x10-6 (Cheng et al., 2013).
Corrected 230Th ages assume the initial 230Th/232Th atomic ratio of 4.4 ± 2.2 x10-6 for material in secular equilibrium with bulk earth 232Th/238U value of 3.8.
