Ivanovich M and Harmon R S Uranium Series Disequilibrium: Nonetheless, correction for the effect of Th incorporated at the time of deposition is extremely important, and has been approached in a number of ways. The stalagmite rupture dated at Thermal ionization mass spectrometry TIMS and inductively coupled plasma mass spectrometry ICP-MS offer significant improvements in counting efficiency and sample throughput compared to traditional decay-counting techniques.

Uranium-thorium datingalso called thorium datinguranium-series disequilibrium dating or uranium-series datingis a radiometric dating technique commonly used to determine the age of calcium carbonate materials such as speleothem or coral. Speleothems and other carbonate deposits such as tufa containing high proportions of detrital material can be difficult to gap dating policy date due to detrital thorium levels causing a high level of error in conventional U-Th disequilibrium dating. Therefore, initial Pa tends to be more significant than initial U th dating speleothems for young gh, although this problem becomes less significant or even insignificant with increasing age.

We present 22 U-series ages for a stalagmite from north-western Cuba based on multi-collector inductively coupled plasma mass spectrometry MC-ICPMS and thermal speelothems mass spectrometry TIMS. Samples measured by MC-ICPMS show a high variability of Th content along the growth axis with some sections significantly affected by initial Th from a detrital phase.
