Magmatic System of the Hainan Plume Revealed by Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The magmatic system of the Hainan plume is important for unraveling the mechanism of intraplate volcanism. We develop a detailed three‐dimensional shear‐wave velocity (Vs) model of the crust and uppermost mantle using ambient noise tomography to investigate the magmatic system of the Hainan plume. Rayleigh wave phase velocity dispersions (5–40

The Uplift of Armorica and the Bretonian Movements of the Variscan Orogeny‐New Insights From Detrital Zircons in the Early Carboniferous Terrigenous Rocks of the Laval Basin (Armorican Massif, France)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract In the French Armorican Massif, the Bretonian phase of the Variscan orogeny has been defined by the Late Devonian (Famennian‐Frasnian) erosion gap, and the Early Carboniferous (Tournaisian) syntectonic terrigenous deposits of the l’Huisserie formation in the Laval basin in the Central‐North Armorican Domain, ascribed to the Armorica ...

New Pattern of Uplift‐Depression of the Pre‐Cambrian Basement in the Sichuan Basin: Constraints From Multi‐Seismic Parameter Imaging

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The structural configuration of the pre‐Cambrian basement in the Sichuan Basin, a highly promising region for hydrocarbon exploration, has been a subject of long‐standing debate. Here, we determined the fine‐scale three‐dimensional seismic models of the Sichuan Basin using 187,356 high‐quality P‐ and S‐wave travel time pairs recorded by 627 ...

High‐Resolution Lithospheric Shear Velocity Structure of the Suqian Segment of the Tanlu Fault Zone From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract To understand causes of the Suqian seismic gap and the 1668 M8.5 Tancheng earthquake, we determine a new 3‐D S‐wave velocity (Vs) model of the lithosphere under the Suqian segment of the Tanlu fault zone in eastern China using ambient noise tomography. Rayleigh wave phase velocity dispersions at periods of 5–33 s are collected from seismograms

Ten Questions of East Asian Tectonics

Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 297-319, April 2025.
Abstract East Asian continental tectonics challenges the plate tectonics paradigm with its diffuse intraplate deformation, magmatism, and earthquakes. Despite extensive studies, fundamental questions persist. This review examines ten critical questions of East Asian tectonics, including the thickness of the continental lithosphere, the origin of the ...

Black Shale Lithofacies of the Wufeng–Longmaxi Formation in the Southeast Margin of Chongqing, China

Geofluids, Volume 2025, Issue 1, 2025.
China’s shale gas has undergone nearly 20 years of exploration; unconventional oil and gas geological evaluation theories and research methods have been greatly enriched, but how to quickly, conveniently, and accurately identify the sweet spots of shale gas is still puzzling many researchers. This study focuses on the black shale of the Wufeng–Longmaxi
