Abstract:

Uranium-series measurements of the speleothem samples from the Cola cave.

The concentrations of 238U and 232Th were determined using the enriched 236U and 229Th isotopes, respectively. delta234Um = {[(234U/238U)sample/(234U/238U)eq] − 1} ×1000, where (234U/238U)sample is the measured atomic ratio and (234U/238U)eq is the atomic ratio at secular equilibrium.
