Evaluating Regional Stress Versus Structural Controls on a Middle Miocene Dike Swarm in the Sanbagawa Metamorphic Complex, Southwest Japan

Island Arc, Volume 35, Issue 1, January/December 2026.
ABSTRACT The Middle Miocene Takaiwa Rhyolite dike swarm in central Shikoku, southwest Japan, provides a key opportunity to evaluate whether arc‐parallel dikes record the regional stress field in a crustal domain with a pervasive ENE–WSW structural grain.

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.

Finit element models of Tertiary paleostress fields in the eastern part of the Tajo basin (Central Spain)

, 1996
Two groups of finite element models have been carried out over Tertiary paleostress fields deduced from fault-slip data in the eastern part of the Tajo Basin.

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.

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.

Tertiary paleostress fields in the eastern part Of the Tajo basin (central Spain)

, 1996
Three compressive pa/eostress fields, which have been active during the Tertiary, have been deduced from fault-slip data in the eastern border of the Tajo Basin. The first one («Iberian» paleostress field) had a N55E maximum horizontal stress (SHMA>) and

Morphological analysis of stylolites for paleostress estimation in limestones surrounding the Andra Underground Research Laboratory site [PDF]

, 2013
International audienceWe develop and test a methodology to infer paleostress from the morphology of stylolites within borehole cores. This non-destructive method is based on the analysis of the stylolite trace along the outer cylindrical surface of the ...
