Abstract

Carbonate speleothems that contain ppb-ppm levels of uranium can be dated by the 238U-234U-230Th and 235U-231Pa disequilibrium techiques. Accurate ages are possible if the initial concentrations of 230Th and 231Pa are well constrained and if the system has remained closed to post-depositional exchange of uranium, thorium, and protactinium.
