Spatial and Temporal Distribution of Salt‐ and Shale‐Detached Contractional Deformation, Mexican Northwestern Gulf of Mexico

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In the northwestern Gulf of Mexico, gravity‐driven contractional deformation is recorded across the Salina del Bravo, the Perdido and Peripheral fold belts, and the Mexican Cordilleras. Integrating seismic interpretation, structural mapping, and analysis, we examine the spatial and temporal partitioning of shortening above three principal ...

Structural evaluation and hydrocarbon potentials of Emil Field, offshore Niger Delta Basin

Results in Earth Sciences
The Emil Field, located in the deep offshore Niger Delta Basin, represents a structurally complex petroleum system shaped by sediment loading, growth faulting, and shale diapirism. This study applies an integrated workflow of seismic interpretation, well

Formation and growth of diapirs in contractional settings: the Mediano anticline and Clamosa diapir case study (Southern Pyrenees) [PDF]

Solid Earth
At the northwestern termination of the South Pyrenean Central Salient, thrust imbrication, detachment folding and diapirism are structurally and genetically related. The La Fueba imbricate system has been folded by the Mediano detachment anticline, while

Timing of the Albano‐Hellenic Paleomagnetic Rotation

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The Aegean arc is the most prominent Mediterranean salient, characterized by significant paleomagnetic rotations along its limbs. Although it is well‐established that the external Ionian and Kruja zones of the Albano‐Hellenides underwent a ∼40° post‐Oligocene clockwise (CW) rotation relative to Africa/Adria, the rotation timing remains debated.

Evidence for the origin of ridges on Europa by means of photoclinometric data from E4 Galileo orbit [PDF]

Geofísica Internacional, 2004
The most commonly observable structures on the surface of the Jovian satellite Europa are the ridges. Geological evidences show that the ridges have been formed continuously for the last 10 million years.

Quantifying Thermo‐Fluid‐Chemical Coupling: Advection Governs Multi‐Phase Zonation and Self‐Sealing in a Hydrate‐Cold Seep System

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Deep fluid advection fundamentally governs the thermal‐fluid‐chemical evolution and distribution of hydrate‐cold seep systems. However, coupled relationships between deep fluid and shallow multiphase dynamics remain inadequately constrained.

Troodos: A Giant Serpentinite Diapir

International Journal of Geosciences, 2011
Troodos is a classical ophiolite complex. It is proposed that the serpentinized harzburgites that now form the top of the mountain and represent the originally lowest part of the ophiolite sequence rose as a diapir. This diapiric rise is caused by the pervasive serpentinization of a suboceanic harzburgite, due to rock-sea water interaction.

Structural Evolution of a Polyphase Salt‐Tectonic System From Syn‐Rift Extension to Syn‐Orogenic Deformation in the Middle Atlas (Oum Er Rbia Region, Morocco)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Salt tectonics has received little attention in the Middle Atlas, despite the widespread occurrence of Triassic evaporites and their potential to exert first‐order control on basin architecture and deformation. This study presents the first integrated analysis of polyphase salt tectonics in the Middle Atlas, focusing on the Oum Er‐Rbia sector,

Geoarchaeological Evidence for the Decline of the Medieval City of Qalhat, Oman

Open Quaternary, 2019
The medieval city of Qalhat was an important trade town along the sea routes in the Indian Ocean. The reasons for the decline of the city are unclear, as the archaeological evidence is inconclusive.
