Elongate summit calderas as Neogene paleostress indicators in Antarctica [PDF]

open access: yesOpen-File Report, 2007
The orientations and ages of elongate summit calderas on major polygenetic volcanoes were compiled to document Miocene to Pleistocene Sh (minimum horizontal stress) directions on the western and northern flanks of the West Antarctic rift system. Miocene to Pleistocene summit calderas along the western Ross Sea show relatively consistent ENE long axis ...

Interaction Between Transverse and Rift Faults During the Initiation of Orogenic Extension: The Case of Sant'Anna Pelago (Northern Apennines, Italy)

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract Sant'Anna Pelago is located near the extensional front of the Northern Apennines (Italy) between Modena and Lucca, an area characterized by multiple lateral steps of the NW‐SE striking tectonic system and orographic divide. The region is affected by significant instrumental seismicity with over a thousand recorded events (0.5 < M < 4.8) from ...

All Aligned on the Western Front of North America? Analyzing the Stress Field in the Northern Cordillera

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract This study presents the first rigorous statistical analysis of the present‐day crustal stress along the western margin of the North American Plate, covering the entire Canadian Cordillera and Alaska. Using circular statistics and geometric tests, we develop a regional stress province model that constrains the directions of first‐order stresses.

From Oblique Thrust to Strike-Slip Fault: Progressive Stages of an Accretionary Wedge Development [PDF]

open access: yesLithosphere
Accretionary wedges of orogenic belts develop differently based on the direction of thrusting, which can be perpendicular to oblique to the belt. In the case of oblique thrusting, stress partitioning occurs, which dissects the accretionary wedge, changes

Determination of present-day stress tensor and neotectonic interval in the Spanish Central System and Madrid Basin, central Spain [PDF]

open access: yes, 1996
A brittle deformation tectonic analysis was performed in central Spain (Spanish Central System and Madrid Basin) in order to decipher and understand the deformation processes that take place in a typical intracontinental zone.

Microstructural Evolution of Carrara Marble During Semi‐Brittle Deformation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Fifteen marble samples were subjected to semi‐brittle deformation through triaxial compression experiments, reaching axial strains of about 0.5%, 1.0%, 2.0%, 4.0%, or 7.5% at temperatures of 20°C, 200°C, or 350°C, under a confining pressure of 400 MPa.

Kinematics of the Havran-Balıkesir Fault Zone and its implication on geodynamic evolution of the Southern Marmara Region, NW Anatolia

open access: yesGeodinamica Acta, 2018
Cenozoic convergence, collision and subsequent subduction between African and Eurasian plates are accommodating in overriding Eurasian plate both forming the Aegean extension and the North & East Anatolian fault zones.
