Seawater (U-234/U-238) during the last 800 thousand years

Abstract:

Constraining the history of seawater (234U/238U) is important because this ratio is used to assess the validity of U/ Th ages, and because it provides information about the past rate of physical weathering on the continents. This study makes use of U-rich slope sediments from the Bahamas in an attempt to reconstruct seawater (234U/238U) for the last 800 kyr. For the last 360 kyr, U/Th dating of these sediments provides ages and initial (234U/238U) values. Sixty-seven samples, largely from mar...
