Compositional and Textural Variability Among Tektites From Indochina and South China: Insights Into the Impact Origin of the Australasian Tektite Strewn Field

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The Australasian tektite strewn field, approximately 0.8 Ma in age, covers nearly 10% of the Earth's surface, making it the largest and most recent strewn field globally. This study provides a comprehensive analysis of the elemental composition and texture of tektites recovered from various locations within the strewn field, particularly ...

Construction of Ultraslow‐Spreading Oceanic Crust: New Insights on Volcanic Processes and Deposits From High‐Resolution Mapping at the Mohns Ridge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The volcanic activity at ultraslow‐spreading ridges is less understood compared with that at faster‐spreading ridges. Studies of year‐to‐year changes along the faster‐spreading ridges have provided important information regarding the size and frequency of eruptions.

Benefits of GNSS Local Observations Compared to Global Weather‐Based Models for InSAR Tropospheric Corrections Over Tropical Volcanoes: Case Studies of Piton De La Fournaise and Merapi

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract From repeat‐pass interferometry, tropospheric signals often prevent the detection of ground deformation signals. In recent years, tropospheric corrections derived from global weather‐based models have been implemented in several InSAR processing chains.

Multi‐Scale Geophysical Imaging of a Hydrothermal System in Yellowstone National Park, USA

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Little is known about the local plumbing systems that fuel Yellowstone's famous hot springs, geysers and mud pots. A multi‐method, multi‐scale geophysical investigation was carried out in the Obsidian Pool Thermal Area (OPTA) to: (a) delineate the lateral extent of the hydrothermal area and associated surface features; (b) estimate the ...
