Morphometric Evidence for Cenozoic Intraplate Reactivation in NW Uruguay

Tectonics, Volume 44, Issue 10, October 2025.
Abstract Located in eastern South America, Uruguay has been considered tectonically inactive since rifting in the Late Cretaceous. Here, we use a high‐resolution digital elevation model and field observations to investigate the presence of recent tectonic activity in the Basaltic Plateau, northwest Uruguay.

Reativation of Taxaquara Fault and its morphotectonic influence on the evolution of Jordão River catchment, Paraná, Brasil

Brazilian Journal of Geology
: The Paraná basin is one of the major morphotectures of the South American continent. Although its tectono-sedimentary evolution has been widely studied and fairly well understood, this paper aims to fill a gap in knowledge comprising the tectonic ...

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

Tectonics, 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

Tectonics, 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.

Structural and stress analysis in mining practice in the Upper Silesian Coal Basin [PDF]

, 2013
The irregular distribution of stress in rock mass is a decisive factor for the origin of rock bursts. Besides, a sound knowledge of stress distribution is very important in the excavation of mine workings. Stress state is affected both by natural stress,

Microstructural Evolution of Carrara Marble During Semi‐Brittle Deformation

Journal 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.
