Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

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

Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

Basin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.

Tectono-karst depressions in the central-western part of the Mehedinţi Mountains (SW Romania)

Travaux de l'Institut de Speologie Emile Racovitza, 2013
The horst structure of the Mehedinţi Mountains, bounded to the east by the Mehedinţi Plateau, and to the west by the Cerna Graben, has been leveled by the Râul Şes II karst planation surface, at an altitude of 1250-1030 m.

Type of Carbonate Production, Sedimentary and Tectonic Evolution of the Pliocene Mixed Carbonate Siliciclastic Unit (Macco) in the Tarquinia Basin, Central Italy

Basin Research, Volume 38, Issue 3, May–June 2026.
Piacenzian mixed carbonate‐siliciclastic succession (‘Macco’ unit) deposited on the passive margin of the Tyrrhenian back‐arc basin. Sedimentation was controlled by syn‐sedimentary tectonics, with NW–SE first‐order faults (3–4 km) creating accommodation space and NE–SW second‐order faults (~0.5 km) influencing facies distribution and growth structures.

Tectonic Interplay in the Gulf of Cagliari (Italy): Extension, Compression and Strike‐Slip Movements

Basin Research, Volume 38, Issue 3, May–June 2026.
Since the Oligocene, extensional tectonics of the Sardinia Rift and Campidano Graben interacted with the collision between Sardinia and northern Africa, generating reverse faults. At the Plio‐Quaternary boundary, compressional tectonics resumed, shaping the southern margin of the gulf through transpressional tectonics of the exposed Ichnusa High ...

Geodetic proof of vertical recent movements at the seism generating zone of Acambay, Mexico

Minería y Geología, 2016
The central territorial belt oriented west-east and located along the parallel 19 in the Mexican Republic, is composed of a complex system of faults, that respond to the consequent morphology of a tension arched system, which has been erected to the ...
