Kinematics of the South Atlantic rift [PDF]

open access: yes, 2013
The South Atlantic rift basin evolved as branch of a large Jurassic-Cretaceous intraplate rift zone between the African and South American plates during the final breakup of western Gondwana.

Permeability Evolution and Gouge Formation During Fracture Shearing

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Hydro‐mechanical processes are crucial in shear‐controlled geoscientific applications such as enhanced geothermal systems and often result in stress‐dependent permeability changes. The present study aims to investigate shear‐induced permeability evolution of a natural sandstone fracture using a novel modeling approach.

Strain partitioning in transpressive shear zones in the southern branch of the Variscan Ibero-Armorican Arc [PDF]

open access: yes, 2003
The Torre de Moncorvo region (NE Portugal) is a key-sector of the Autochthon Domain of the Iberian Terrane. The region experienced Variscan deformation in the southern branch of the Ibero-Armorican Arc wherein the early structures (of Upper Devonian age -

Tectonic implications of transpression and transtension: Upper Rhine Graben [PDF]

open access: yesTectonics, 2005
Seismic reflection data from the Upper Rhine Graben (URG) show a series of synclines along the linear eastern boundary faults from north of Karlsruhe to the Jura Mountains. Similar structures do not characterize the northern segment of the graben. The synclinal shape is portrayed by inversion related to transpression on the linear boundary faults ...

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.

Characterizing Seismo-stratigraphic and Structural Framework of Late Cretaceous-Recent succession of offshore Indus Pakistan

open access: yesOpen Geosciences, 2018
Regional seismic reflection profiles and deep exploratory wells have been used to characterize the subsurface structural trends and seismo-stratigraphic architecture of the sedimentary successions in offshore Indus Pakistan.

Provenance Reassessment of Eocene Turbidites, New Caledonia: Inferences for Obduction Models

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Provenance of pre‐obduction Eocene turbidites from New Caledonia is used to better constrain their geodynamic context and inform debate on subduction polarity. Chemical compositions of detrital clinopyroxenes in arenites are compared against potential sources.

Structural control on gold mineralization in the Satulinmäki and Riukka prospects, Häme Schist Belt, southern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2007
The Satulinmäki and Riukka prospects located in the Häme Schist Belt in southern Finland are dominated by mafic and intermediate to felsic metavolcanic rocks of the Forssa Group formed in a continental arc setting.

Flexural-slip folding in buckling phases of orogenic belts: Insight into the tectonic evolution of fault splays in the East Iran orogen

open access: yesFrontiers in Earth Science, 2023
Introduction: The East Iran orogen has experienced multiple buckling phases resulting in the formation of strike-slip fault splays. The geometric and kinematic characteristics of these splays are influenced by folding mechanisms.
