Uranium-Thorium dating is based on the detection by mass spectrometry uranium-thorium dating accuracy both the parent U and daughter Th products of decay, through the emission of an alpha particle. The decay of Uranium to Thorium is part of the much longer decay series begining in U and ending in Pb. With time, Thorium accumulates in the sample through radiometric decay. The method assumes that the sample does not exchange Th or U with the environment i. The method is used for samples that can retain Uranium and Thorium, such as carbonate sediments, bones and teeth. Ages between andyears have been reported. Augustinus, P. Journal of Quaternary Science

Uranium—thorium dating , also called thorium dating , uranium-series disequilibrium dating or uranium-series dating , is a radiometric dating technique established in the s which has been used since the s to determine the age of calcium carbonate materials such as speleothem or coral. Instead, it calculates an age from the degree to which secular equilibrium has been restored between the radioactive isotope thorium and its radioactive parent uranium within a sample. Thorium is not soluble in natural water under conditions found at or near the surface of the earth, so materials grown in or from this water do not usually contain thorium. As time passes after such material has formed, uranium in the sample with a half-life of , years decays to thorium At secular equilibrium, the number of thorium decays per year within a sample is equal to the number of thorium produced, which also equals the number of uranium decays per year in the same sample.
