Short summary
We performed a statistical analysis of high-precision U–Pb zircon age distributions. This reveals that volcanic and porphyry zircon age distributions are skewed to younger ages, whereas plutonic age distributions are skewed to older ages. We show that this is caused by truncation of zircon crystallisation by magma evacuation rather than differences in magmatic flux. Our contribution has key implications for modelling of magma dynamics and eruption ages using zircon age distributions.

We present the first community-wide evaluation of the reproducibility of U–Pb zircon geochronology by isotope dilution thermal ionisation mass spectrometry (ID-TIMS). Eleven labs analysed aliquots of the same, homogenised, pre-spiked solution of natural zircon, which removed geological bias inherent to using heterogeneous natural zircon grain populations. We discuss remaining sources of inter-lab bias and propose areas of improvement to analytical procedures.

RA138 is a new reference material for U–Pb dating of carbonate samples via laser ablation inductively coupled plasma mass spectrometry. RA138 exhibits variable U–Pb ratios and consistent U content, resulting in a precise isochron with low uncertainty. Isotope dilution thermal ionization mass spectrometry analyses fix a reference age of 321.99 ± 0.65 Ma. This research advances our ability to date carbonate samples accurately, providing insights into geological processes and historical timelines.

Acid leaching is used to remove radiation-damaged portions of zircon crystals prior to U–Pb dating to improve the accuracy of datasets. We test how the temperature and duration of acid leaching affect geochronological and geochemical outcomes. We build a framework that relates radiation damage, zircon solubility, and Pb loss.

This contribution presents a new reference material, ASH-15 flowstone with an age of 2.965 ± 0.011 Ma (95 % CI), to be used for in situ U–Pb dating of carbonate material. The new age analyses include the use of the EARTHTIME isotopic tracers and a large number of sub-samples (n = 37) with small aliquots (1–7 mg) each that are more representative of laser-ablation spot analysis. The new results could improve the propagated uncertainties on the final age with a minimal value of 0.4 %.

Short summary
We present a pioneering method for high-precision U–Pb dating of individual growth zones in zircon. These micrometer zones in single grains can record key geological processes from magma priming prior to eruptions to planetary formation, yet dating them at high precision has so far been technically challenging. Our method employs two cutting-edge microbeam techniques to microsample these growth zones for high-precision dating, allowing us to tackle a number of outstanding research questions.
