Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...

Reconstruction of Rock Uplift in South‐Central Germany Since Late Mesozoic Times

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Rock uplift and denudation act as first‐order controls on geological processes that influence atmospheric and ocean composition, and landscape‐forming processes. However, estimating rock uplift rates remains challenging due to the temporal averaging of rates calculated from individual thermo‐ or geochronologic systems.

Zircons from Eclogite-Associated Rocks of the Marun–Keu Complex, the Polar Urals: Trace Elements and U–Pb Dating

Geosciences
The Marun–Keu complex plays a significant role in our understanding of the geological evolution of the Ural orogen; however, it remains poorly understood.

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Precision and Accuracy in Geochronology

, 2017
Geochronology in Earth and Solar System science is increasingly in demand, and this demand is not only for more results, but for more precise, more accurate, and more easily interpreted temporal constraints.

Evidence for Submarine Landslides at Climate Transitions in a High Arctic Fjord (Grise Fiord, Nunavut)

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Seafloor mapping in a high Arctic fjord (Grise Fiord) revealed many submarine landslides triggered by iceberg groundings, coastal debris flows and delta collapses. The dating of three of them suggests that they occurred at past climate transitions. ABSTRACT Arctic fjords are experiencing rapid environmental change driven by amplified high‐latitude ...

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, Volume 41, Issue 7, Page 1020-1035, October 2026.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, Volume 41, Issue 7, Page 1060-1077, October 2026.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.

Sensitization of OSL Signals in Quartz and Provenance Implications: Insights From Multi‐Spectroscopic Analysis of Quartz From Multiple Geological Settings

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Quartz optically stimulated luminescence (OSL) sensitivity and electron spin resonance (ESR) signals have been empirically proposed as indicators of sediment provenance. OSL sensitivity is defined as luminescence produced per unit dose (Gray: Gy) per unit mass (mg).
