Short summary

In this study, we built a statistical model to determine the initial δ²³⁴U in submerged calcite crusts that coat the walls of Devils Hole 2 (DH2) cave (Nevada, USA) and, using a ²³⁴U–²³⁸U dating method, extended the chronology of the calcite deposition beyond previous well-established ²³⁰Th ages and determined the oldest calcite deposited in this cave, a time marker for cave genesis. The novel method presented here may be used in future speleothem studies in similar hydrogeological settings.
