Structural evolution characteristics and hydrocarbon accumulation of Jinma-Yazihe area

open access: yesYouqicang pingjia yu kaifa, 2020
Jinma-Yazihe area is located at the junction of Longmenshan fold-thrust belt and Sichuan basin. Based on the 3D seismic data, the characteristics of faults and the process of tectonic evolution are analyzed.

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)

open access: yesGeochemistry, 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

open access: yesJournal 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 ...

A Late Paleozoic Hydrothermal Gold Mineralization Event in the Northern Margin of the North China Craton: Evidence of In Situ Apatite U‐Pb Dating and Hg Isotope Tracing of the Giant Hadamengou Gold Deposit

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The northern margin of the North China Craton (NCC) hosts large numbers of hydrothermal gold deposits, with mineralization ages ranging from the Paleozoic to Mesozoic eras. The genesis of these deposits has been primarily ascribed to magmatic‐hydrothermal or crustal‐metamorphic fluid models. The Hadamengou gold deposit (>170 t Au), the largest

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

open access: yesJournal 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

open access: yesActa 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 ...

Tectonic evolution and mineralization exploration of Lujing uranium ore field, South China

open access: yesScientific Reports
Granite-type uranium deposit is one of the most important uranium deposit types in China, with orebodies strongly controlled by structures. Previous studies of the Lujing ore field mainly focused on metallogenic genesis and Yanshanian structure, which ...

Permian arc magmatism in Mindoro, the Philippines: An early Indosinian event in the Palawan Continental Terrane

open access: yesTectonophysics, 2010
Abstract Dating of igneous and detrital zircons derived from the metamorphic complex that forms northeastern Mindoro (Philippines), reveals an episode of Middle to Late Permian (250–270 Ma) magmatism. The new age data confirm the previously contentious pre-Mesozoic age of the metamorphics and suggest that they are part of the rifted margin of SE ...

Correlation of detrital zircon ages among the Nanpanjiang basin, the Babu–Cao Bang tectonic belt, and the Northern Vietnam terrane: Tectonic implications

open access: yesDizhi lixue xuebao
Objective  During the opening and closing of the Paleo-Tethys ocean, multiple continental blocks rifted from the northern margin of Gondwana, drifted northward, and eventually merged with the southern boundary of the Asian continent, forming multiple ...
