Abstract
Radiocarbon activities and uranium isotopic disequilibria were measure d in water samples from both the sandy Pleistocene coastal aquifer and within the upper Cretaceous Judea Group carbonate aquifer of northwes tern Israel. The samples in both aquifers exhibit a decrease in C-14 a ctivity that is concomitant to the growth in U-234-excess. This sugges ts that under specific conditions, U-234-excess dating of groundwater can be used to corroborate C-14 dates, while offering the possibility of extending the range of dating of groundwater beyond that of C-14.
