Contribution of aerogravity data interpretation to the study of the deep structure of Agadem petroleum block (Niger)

Geodesy and Cartography, 2023
The main information provided by gravity maps is the geographical distribution of density heterogeneities in the subsurface. It is an important tool widely used for the mapping of geological structures, especially in the oil industry.

Stratigraphy and petrology of the Miocene Montjuic delta: (Barcelona, Spain). [PDF]

, 2012
The Neogene rift in the Catalan Coastal Ranges, which is located in the NE part of the Eastern Iberian Margin, corresponds to a system of grabens formed at the nort h - we s t e rn edge of the Valencia Trough.

Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

Sedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...

Trench‐Parallel Fluid Migration and Its Transient Discharge in a Cold Subduction Zone Decoded by Geochemistry of Subducted Cherts

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The presence of fluid plays a critical role in controlling the fault slips and the seismogenesis in subduction zones. However, the origins and pathways of the fluid remain poorly understood. In this study, we examined the Inuyama sequence in the Mino belt of Japan, which is an on‐land analog of a cold subduction zone such as the Japan Trench ...

Active Tectonics in Southern Xinjiang, China: Analysis of Terrace Riser and Normal Fault Scarp Degradation Along the Hotan-Qira Fault System [PDF]

, 1993
The northern piedmont of the western Kunlun mountains (Xinjiang, China) is marked at its easternmost extremity, south of the Hotan-Qira oases, by a set of normal faults trending N50E for nearly 70 km.

Imaging Continental Rifting Structures From Eastern Gondwana Breakup by Full‐Waveform Inversion of Marine Wide‐Angle Seismic Data

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Lord Howe Rise (LHR), a submerged continental fragment of Zealandia offshore eastern Australia, provides a rare opportunity to investigate the fine‐scale structure of a magma‐poor rifted margin. This study applies full waveform inversion (FWI) of 2D marine wide‐angle seismic data acquired with densely deployed ocean‐bottom seismometers ...

On the Move: 2023 Observations on Real Time Graben Formation, Grindavík, Iceland

Geophysical Research Letters
Grabens, or valleys formed during extensional tectonic events, are common but rarely observed during formation. In November 2023, inelastic surface deformation formed abruptly along Iceland's plate boundary in Grindavík. We documented graben formation in

Fault‐Induced Hydration and Serpentinization of the Incoming Lithosphere Enhances Intra‐Slab Seismicity Offshore Taltal (∼25°S), Northern Chile

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The northern Chilean margin is one of the most seismically active subduction zones, with a high potential for future megathrust earthquakes. The tectonic structure and the state of hydration of the incoming Nazca Plate, and their control on seismogenesis are poorly known, as the offshore domain remains largely unexplored. Here, we present high‐
