U-234/U-238 RATIOS IN QUATERNARY PLANKTONIC-FORAMINIFERA

Abstract:

234U 238U measurements on foraminifera could potentially provide an indicator of foraminifera diagenesis, a proxy for past seawater 234U 238U and, significantly, a direct dating tool for foraminifera. Such measurements are complicated, however, by the very low concentration of U in foraminifera and by the much higher U content of the Mn-rich diagenetic layer which forms on them within the sediment column. Here, we demonstrate that 234U 238U measurements can be made successfully on U samples...
