Multiple fault reactivation within the intra-continental Rhine-Bresse Transfer Zone (La Serre Horst, eastern France) [PDF]

, 2009
Thermochronological, structural and kinematic analyses demonstrate the influence of Late Paleozoic basement structures on the localization and evolution of the Rhine-Bresse Transfer Zone (RBTZ), a central segment of the Paleogene European Cenozoic Rift ...

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.

A Spreading‐Rate Dependence for Periodic Signals Embedded in Otherwise Aperiodic Abyssal Hills

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract I present evidence, through an empirical pre‐whitening analysis, that periodic signals are embedded in otherwise aperiodic abyssal hills across paleo‐spreading rates ranging from 1 to 9 cm/yr (half rate). Data are comprised of archival trackline and multibeam bathymetry profiles in north and south Atlantic Oceans, Pacific‐Antarctic Ridge ...

Synclinal-horst basins: Examples from the southern Rio Grande rift and southern transition zone of southwestern New Mexico, USA [PDF]

, 2003
In areas of broadly distributed extensional strain, the back-tilted edges of a wider than normal horst block may create a synclinal-horst basin. Three Neogene synclinal-horst basins are described from the southern Rio Grande rift and southern Transition ...

Seismic Data Interpretation: A Case Study of Southern Sindh Monocline, Lower Indus Basin, Pakistan [PDF]

Mehran University Research Journal of Engineering and Technology, 2015
The Sindh monocline in Lower Indus Basin is an important oil and gas producing area of Pakistan where a large number of oil, gas and condensate fields have been discovered from structural traps.

The 2025 Mw 7.6 Aomori‐Oki Megathrust Sequence and a Slip‐Parallel Seismic Belt to the Trench

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The 2025 Mw 7.6 Aomori‐Oki earthquake nucleated near the 1968 Mw 8.3 Tokachi‐Oki rupture area. Our waveform inversion reveals large slip (>1 m) extending ∼40 km northward from the hypocenter, overlapping the inferred 1968 northern asperity. Minor secondary slip (0.2–0.6 m) was resolved ∼60 km updip, and high‐precision relocations show that ...

Low Hazard–High Risk: A Case Study of the Active Mangatangi Fault

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Activity on low deformation rate faults are challenging to quantify and comparatively understudied. One such fault, the Mangatangi Fault, strikes NE‐SW along the southeastern flanks of the Hunua Ranges c. 52 km south of New Zealand's most populous city, Auckland.

Dating of active normal fault scarps in the Büyük Menderes Graben (western Anatolia) and its implications for seismic history [PDF]

, 2019
Fault scarps, if well-preserved, include precise evidence of past earthquakes. Using cosmogenic 36Cl dating, the timing and slip of paleoearthquakes are recoverable beyond the available earthquake archives.

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.
