Global Glacial Rock Weathering Signature Depends on Competing Contributions From Ice Sheets and Alpine Glaciers

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Rock weathering influences Earth's atmosphere and climate. The dissolution of silicate minerals draws down atmospheric CO2 while sulfide oxidation coupled with carbonate dissolution releases CO2. Alpine glacier rock weathering causes high sulfide oxidation and carbonate dissolution.

Electrochemical Evaluation of Pyrite Films Prepared by Plasma Spraying

open access: yes, 2009
Thermally activated batteries use electrodes that are typically fabricated by cold pressing of powder. In the LiSi/FeS2 system, natural (mineral) pyrite is used for the cathode.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1451-1463, June 2026.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Contrasting Hydrosedimentary Dynamics in Two Mediterranean Watersheds: Insights From Flood Hydrograph Decompositions

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
This paper highlights the role of groundwater inputs to the river system during flood events in diluting suspended sediment concentration, in two small badland catchments with contrasting vegetation cover. The findings underline the importance of isolating the surface runoff component to better understand and prioritise hydrosedimentary processes ...
