In this contribution, we demonstrate in situ monazite lutetium–hafnium dating and compare results with uranium–lead dating. We present data from monazite reference materials and complex samples to demonstrate the viability of this method. We show that in situ lutetium–hafnium dating of monazite can resolve multiple age populations and may find use in scenarios where the uranium–lead system has been compromised.

This study explores quartz veins in Germany's Rursee area, formed during the Variscan Orogeny and later reactivated by tectonic activity in the Jurassic–Cretaceous period. Using advanced isotopic dating techniques, it examines how these veins influenced fluid flow and quartz recrystallization. By tackling the challenges of dating fluid activity, this research offers new insights into argon gas degassing in quartz minerals.

We use a method called cosmogenic nuclide dating on bedrock surfaces and moraine boulders to determine the relative length of time an alpine glacier was larger or smaller than its current extent over the past 15 000 years. We also discuss several important limitations to this method. This method gives information on the duration of past ice advances and is useful in areas without other materials that can be dated.

Sedimentary rocks are typically dated indirectly, by comparing the fossil content of basins with the geological timescale. In this study, we employed an absolute dating approach to date 19\,Myr old sediments in the Paris Basin, using uranium–lead dating of calcite nodules associated with soil formation. The precision of our new ages enable more accurate comparisons (independent of their fossil contents) between the Paris Basin and other basins of similar age.

The equatorial Pacific is an important region that helps determine Earth's climate. This work presents new age models for two sediment core sites located in that region, spanning the last 280 kyr. Our age models are based on new radiocarbon dates and oxygen isotope measurements. We also use the oxygen isotope data to infer changes in sea surface salinity patterns, finding evidence for a change in the position of the Intertropical Convergence Zone (ITCZ) on glacial and interglacial timescales.

OCTOPUS v2.3 updates CRN Denudation, adding 1311 new river basins to the CRN Global and CRN Australia collections, totalling 5611 basins with recalculated beryllium-10 denudation rates and 561 with aluminium-26 rates. New fields include basin centroid latitude, effective atmospheric pressure, glacier extent, and quartz-bearing lithology percentages, improving data quality and interoperability with online erosion calculators.

This article presents a non-destructive method for studying laminated sediments with X-ray micro-computed tomography (μCT). It aims to study the possibility of using μCT as an analytical tool to analyse varved sediments in the context of paleoclimatic studies. As a result, µCT offers the possibility of doing fast analysis and constitutes a powerful tool to improve the quality of results through the access of a 3D view, allowing for choosing the most representative part of a varved record.
