Uranium\u2013lead (U-Pb) dating is an established radiometric dating method in Earth sciences. The method is commonly applied to the mineral zircon which incorporates U and Th but rejects Pb during crystallization. The method relies on two decay series; 238<\/sup>U to 206<\/sup>Pb with a half-life of 4.47 billion years, and 235<\/sup>U to 207<\/sup>Pb with a half-life of 710 million years. In U-Pb dating of zircon by LA-ICP-MS, there is a need for high precision and accurate measurements of these two elements and their isotopes.<\/p>\n\n\n\n

This study by Thompson et al. compares U-Pb zircon dating by laser ablation coupled to a time-of-flight inductively coupled plasma mass spectrometer (LA-ICP-TOFMS) and a quadrupole mass spectrometer (LA-ICP-QMS). The results show that both ICP-MS types produce similar levels of precision and accuracy for most U-Pb ages in zircon, especially if the 235<\/sup>U decay series is considered. The advantage of TOFMS is that trace element concentrations (e.g. rare earth elements) in zircon are measured simultaneously along with the U-Pb isotope data.<\/p>","protected":false},"excerpt":{"rendered":"
