Effect of Solution Temperature on the Microstructure of 18%Ni Maraging Steel Modified With Nb—X‐Ray Diffraction and Electron Backscattered Scanning Diffraction (EBSD) Analyzes

X-Ray Spectrometry, Volume 54, Issue 5, Page 547-555, September/October 2025.
ABSTRACT Maraging steels are high strength alloys used in applications that require both high mechanical strength and toughness. To achieve these properties, one of the heat treatments applied is solution treatment, although it can reduce toughness.

3D Reconstruction of Equatorial Plasma Bubbles Using EOF and GNSS Radio Occultation Data From MSS‐1 and COSMIC‐2

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract This study presents initial scientific insights obtained from Radio Occultation (RO) observations of ionospheric irregularities and scintillation at equatorial and low latitudes collected by the Macau Science Satellite‐1 (MSS‐1). With a specific focus on the South Atlantic Anomaly (SAA) region, an Empirical Orthogonal Function (EOF ...

Resolving Crustal and Subcrustal Dynamic Sources in Continental Arc Magmas: The Cenozoic Andean Arc of Central Chile

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract The Andean margin of Central Chile (∼32°40′–34°30′S) records abundant Cenozoic arc magmatic activity with variable compositional characteristics. This is examined through the analysis of an extensive database of new and published whole‐rock geochemistry and Sr‐Nd isotopic compositions, in addition to zircon Hf and O isotopic compositions.

Northwest Africa 16788: The Largest Known Individual Martian Meteorite—A New Olivine Microgabbroic Shergottite and Its Implications for Martian Magmatism

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We present a comprehensive study of a new Martian meteorite, Northwest Africa (NWA) 16788, found in the Sahara Desert in July 2023. This specimen constitutes the largest known individual meteorite of Martian origin, with a total weight of ⁓25 kg. A detailed mineralogical and geochemical investigation identifies NWA 16788 as an enriched olivine

Geochemistry of Ocean Floor and Fore-arc Serpentinites: Constraints on the Ultramafic Input to Subduction Zones [PDF]

, 2017
We provide new insights into the geochemistry of serpentinites from mid-ocean ridges (Mid-Atlantic Ridge and Hess Deep), passive margins (Iberia Abyssal Plain and Newfoundland) and fore-arcs (Mariana and Guatemala) based on bulk-rock and in situ mineral ...

Disentangling Partial Melting and Crustal Recycling Signatures in Ocean Island Basalts With Multivariate Statistics

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Ocean island basalts (OIB) provide valuable constraints on mass exchange between the mantle and crust. When appropriate compositional data transformations are applied, multivariate analyses of OIB compositions can be used to infer mantle source heterogeneity and elucidate its driving processes.

Back to the Source: Connecting the Seismological Observations of Le Teil Earthquake (Mw 4.9, 2019/11/11, France) to the Local Geology

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The spatial distribution of seismicity in active fault zones depends primarily on the geometry of the fault networks. However, recent advances suggest that seismic activity may also be controlled by the rheology of the geological units surrounding fault zones. In the present work, we use seismological and geological analyses to investigate the

Monitoring Water Content Variations From Seismic Noise in a Controlled Laboratory Experiment: A Quantitative Approach Combining Poroelastic Predictions With Kernel Wave Sensitivity Weighting

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Despite the existence of various hydrological and geophysical methods for characterizing the vadose zone and groundwater, it remains challenging to implement cost‐effective, accurate, and efficient techniques for their long‐term monitoring with high spatial resolution. A growing number of recent studies suggest that seismological methods based
