A stand-alone data analysis application for Th/U dating on multi-collector inductively coupled plasma mass spectrometers features a Python-based algorithm with a graphical user interface. It handles data treatment, corrections, age calculus, and error estimation and supports various detector layouts including Faraday and electron multiplier detectors. Key features include reproducibility, user-friendly reanalysis, and automated data storage. A case study demonstrates the software’s performance.

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.

The timing of an ancient gravity slide that originated in the Marysvale volcanic field (Utah) is constrained using ⁴⁰Ar/³⁹Ar dating of pseudotachylyte, a friction-induced glass that is generated during slide movement, and the volcanic tuffs that were displaced by the slide and those that overly the slide mass. Our results suggest that the Sevier gravity slide occurred at 25.25 Ma. The removal of such a large volume of material likely allowed for the eruption of the Antimony Tuff at 25.19 Ma. 

We present the first new image-based study to reveal how choices made by different analysts affect the results obtained by fission-track analysis. Participants analyzed an identical image dataset with varying grain quality. Experienced analysts tend to select lower numbers of unsuitable grains and conduct lower numbers of invalid length measurements. Fission-track studies need image data repositories, teaching modules, guidelines, an open science culture, and new approaches for calibration.

We apply luminescence dating of feldspars to establish a geochronological framework for the sequence of accretionary hillslope deposition at Jojosi, which contains important archaeological artefacts. We test and evaluate four different dose models and their applicability to single-grain and multi-grain data sets containing up to 67 % saturated grains. Our results constrain erosional and depositional processes from 100–700 ka and human occupation of the area in early MIS 5 and late MIS 6.

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.

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.

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.
