Short summary
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.

Short summary
The “Likhall” bed helps to constrain the timing of increased meteorite bombardment of the Earth during the Ordovician period. It is important to understand the timing of this meteorite bombardment when attempting to correlate it with biodiversity changes during the Ordovician period. Calibrating a good age for the “Likhall” bed is, however, challenging and benefited in this study from advances in sample preparation.

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
Zircon in highly differentiated systems such as rare-metal granites often exhibits unusual texture and composition that need to be clarified. Based on a detailed study on zircon from the Beauvoir rare-metal granite (France), we show that zircon crystals were partially replaced during the magmatic–hydrothermal transition of these systems, resulting in a significant change in their crystal texture and chemistry.
