Spatial-Temporal Evolution of Extensional Faulting and Fluid Circulation in the Amatrice Basin (Central Apennines, Italy) During the Pleistocene

Frontiers in Earth Science, 2020
In extensional continental settings, crustal-scale normal faults can accommodate deformation and subsidence at their hanging wall via activation and deactivation of subsidiary tectonic structures.

Paleostress analysis as a key to margin extension: The Penghu Islands, South China Sea [PDF]

Tectonophysics, 1990
Abstract The Penghu Islands belong to the Eurasian passive margin, west of the collision zone of Taiwan. From south to north, the South China Sea basins become narrower and disappear in the Taiwan Strait area. The presence of the Penghu Islands allow description of the tectonic evolution of the margin through the reconstruction of tectonic ...

Contemporaneous Stress in Taiwan: Evidence for Orogen‐Parallel Extension and Lower Crustal Extrusion

Tectonics, Volume 44, Issue 11, November 2025.
Abstract Syn‐to late‐orogenic extension caused by gravitational collapse is a process that has been documented in most orogens. In this paper, we investigate the contemporaneous stress field in Taiwan to examine syn‐orogenic extensional faulting and the possible gravitational collapse modes by which it is taking place.

Constraining the Kinematics of the Victoria Microplate and the Northern Western Branch of the East African Rift System

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The fragmentation of continents results in microplates that rotate to accommodate the lateral propagation of bounding rifts. Yet, the relationships between microplate rotation rates, fault slip, and kinematics at propagating rift tips remain unknown.

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.

Paleostress field reconstruction and revised tectonic history of the Donbas fold and thrust belt (Ukraine and Russia). [PDF]

, 2003
In the WNW-ESE Donbas fold belt (DF), inversion of 3500 microtectonic data collected at 135 sites, in Proterozoic, Devonian, Carboniferous, and Cretaceous competent rocks allowed reconstruction of 123 local stress states.

y-gRaph: An OpenOffice application to reconstruct paleostress fields from striated faults

, 2020
An application (y-gRaph) to reconstruct paleostress fields from faults striations by means of the y–R diagram method is here presented. Based on modified Bott´s equation, the diagram relates y (azimuth of the maximum horizontal stress axis) and R (stress

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.
