Abstract

The concentration of uranium has been measured using the fission track technique in vadose and freshwater phreatic cements from the South Joulters Cay, in The Bahamas. These analyses reveal dramatic differences in the U concentration of vadose (<0.28 ± 0.11 ppm) and freshwater phreatic (1.80 ± .75 ppm) cements. The clear difference in the U concentrations of cements in these two zones may enable the U concentration of cements to be used as an indicator of paleo-water tables in ancient rocks even where other geochemical and petrographic evidences are equivocal. -from Authors
