U-series dating is a family of methods which can be applied to different materials over different time ranges. Liritzis Ioannis. Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent U and daughter Th products of decay, through the emission of an alpha particle. The U-series laboratory focuses on development and application of U-series dating techniques to provide a robust chronological framework for palaeoclimatology, archaeology and human evolution. Attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth.

By measuring U, Th, and He, the time when the He trapping process started can be determined. This is the core of the Uranium-Series laboratory. Abstract This paper presents a significantly simplified method for in-situ U-Th-He dating removing the need to know any absolute concentrations or ablation pit volumes. Uranium—thorium datingalso called thorium datinguranium-series disequilibrium dating or uranium-series datingis 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. Uranium series: The radioactive decay series that starts with U, U and Th and ends with stable isotopes of Pb, Pb and Pb, respectively.
