Thorium / uranium dating of stalagmite PR-LA-1 (Cueva Larga, Puerto Rico)


Activity ratios were corrected for initial Th assuming an detrital weight ratio 232Th/238U = 0.13 ± 0.04 (corresponding to an activity ratio of the detritus in secular equilibrium of (230Th/232Th)detr = 23.7 ± 7.5), and secular equilibrium of the detritus. Ages are calculated using the decay constants by Cheng et al. (2000).
