Characterization of refractory aerosol particles collected in the tropical upper troposphere–lower stratosphere (UTLS) within the Asian tropopause aerosol layer (ATAL) [PDF]

Atmospheric Chemistry and Physics
Aerosol particles with diameters larger than 40 nm were collected during the flight campaign StratoClim 2017 within the Asian tropopause aerosol layer (ATAL) of the 2017 monsoon anticyclone above the Indian subcontinent.

Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Chrome incorporation in high-pressure Fe–Mg oxides [PDF]

European Journal of Mineralogy
The occurrence of Cr-bearing oxide phases as inclusions in diamonds and in extraterrestrial materials has the potential to serve as an indicator of formation conditions.

Faults as Volumetric Weak Zones in Reservoir-Scale Hydro-Mechanical Finite Element Models—A Comparison Based on Grid Geometry, Mesh Resolution and Fault Dip

Energies, 2020
An appropriate representation of faults is fundamental for hydro-mechanical reservoir models to obtain robust quantitative insights into the spatial distribution of stress, strain and pore pressure.

Distinct Transcrustal Evolutions of Komatiitic Primitive Magma: Implications for the Compositional Dichotomy of Continental Flood Basalts

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The origin of the compositional dichotomy between high‐Ti and low‐Ti basalts in continental flood basalt provinces remains debated. Most existing studies attribute this dichotomy directly to variations in primitive magma composition to circumvent the complexities of significant evolutionary processes, such as multiphase fractional ...

Refining point-cloud neighborhood construction for improved classificationGithubZenodoZenodo

Science of Remote Sensing
3D point clouds enable us to capture the structure of our environment in high detail. In the context of urban areas, point clouds allow us to segment single objects, detect changes, and generate detailed maps of highly complex scenes.

Zwischen Flexibilisierung und Stillstand. Raumzeitliche Arrangements und soziale Ungleichheiten in der Auslagerung von Hausarbeit über städtische Lieferdienste [PDF]

Geographica Helvetica
In the course of the Covid-19 pandemic, class diagnostic narratives surrounding an emerging servant economy gained traction also in Europe. Especially grocery and food-delivery services in larger cities became emblematic for an urban middle class ...

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Recording Kimmeridgian Palaeoclimate Changes Using Biofacial and Isotopic Analyses of Benthic Foraminifers From Normandy (Northwest France)

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract During the Kimmeridgian, the Wealdian Basin experienced several periodic disaerobic events, interpreted as the result of extensive rainfall patterns, high sea level and moderate stratification of the water column. These events are recorded in different regions of UK and France.

Dual clumped isotopes in foraminiferal calcite reveal kinetic bias in some species

Communications Earth & Environment
Clumped isotope (∆47) analyses of foraminifera provide a powerful means to reconstruct upper and bottom water temperatures, independent of seawater δ18O and elemental composition.
