A three-dimensional study of a crustal low velocity region beneath the 9,3'N overlapping spreading center [PDF]

, 2003
Overlapping spreading centers (OSCs) play a key role in models of magma distribution at fast spreading ridges. To investigate the relationship between ridge-axis discontinuities and magma supply, we conducted a three-dimensional seismic reflection and ...

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.

Quantitative Morphometry of the Ape Cave Lava Tube: A Statistical Framework for Terrestrial Analogue Studies of Planetary Subsurface Voids

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Recent discoveries suggest that intact lava tubes exist in the Moon and Mars, crucial for establishing long‐term habitable areas to protect future lunar and Martian dwellers from surface risks. Considering planetary lava tubes as potential natural shelters requires understanding their internal complexity, which is challenging due to the lack ...

Basalt Fiber Surface Modification for Improved Interaction With Polyamide‐6 for High‐Performance Automotive Applications

Polymer Composites, Volume 47, Issue 20, Page 18176-18190, 20 October 2026.
Amino‐silane treatment improves the basalt fiber–PA6 interface, enhancing composite performance. ABSTRACT Basalt fiber‐reinforced polymer (BFRP) composites have emerged as sustainable alternatives to glass fiber (GF) composites, but their performance is often controlled by the quality of the fiber–matrix adhesion.

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Thermal model of the Vesuvius magma chamber [PDF]

, 2006
A thermal modeling of the Vesuvius is presented, based on its magmatic and volcanic history. A 2D numerical scheme has been developed to evaluate the heat transfer inside and around a magma body, the latent heat of crystallization and the inputs of magma
