Short summary
RA138 is a new reference material for U-Pb dating of carbonate samples via LA-ICP-MS. RA138 exhibits variable U/Pb ratios and consistent U content, resulting in a precise isochron with low uncertainty. ID-TIMS analyses fix a reference age of 321.99 ± 0.65 Ma. The observed systematic uncertainty challenges previous estimates. This research advances our ability to date carbonate samples accurately, providing deeper insights into geological processes and historical timelines.

The `Likhall´ zircon 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 study re-evaluates the characterization of the Permian–Triassic boundary based on high-precision U-Pb geochronology from two marine sections (Dongpan and Penglaitan) with continuous and conformable stage boundaries in the Nanpanjiang Basin (southern China). These new dates provide the basis for a first proof-of-concept study utilizing a Bayesian statistic age–depth chronology comparing these two sections with the Global Stratotype Section and Point at Meishan (western China).

Short summary
We present new U–Pb age data to provide insights into the source of sediment for the Molasse Sedimentary Basin in Switzerland. The paper aims to help shed light on the processes that built the Central Alpine Mountains between ~35 and ~15 Ma. A primary conclusion drawn from the results is that at ~21 Ma there was a significant change in the sediment sources for the basin. We feel this change indicates major tectonic changes within the Central Alps.

Short summary
This paper investigates the numerical age of the J–K boundary that remains one of the last main Phanerozoic system boundaries without an adequate constraint by adequate radioisotopic ages. Here we find that there is potentially 4 Myr of difference between the current age of the J–K boundary and our data.
