Coupled uranium isotope and sea-level variations in the oceans
Description
Globally, rivers supply uranium to the oceans with excess 234U relative to secular equilibrium and 234U taken-up by corals can be used for dating. In addition, the 234U abundance in sea water, at the time the coral was growing, can be measured independently. The veracity of U-series ages used in determining past sea-level variations is dependent on selecting pristine corals free from diagenetic alteration. A quantitative test for alteration assumes invariant 234U abundances in the oceans for at...[Show more]
