Oligocene/Miocene Rotational Block-Movement and Paleostress Field of Japan

Journal of geomagnetism and geoelectricity, 1986
On the basis of compilation of paleomagnetic direction data, the mid-Cenozoic geography and tectonic stress field of the northeastern and southwestern Japan were restudied. Variations in paleomagnetic directions among the three tectonic provinces (northern, central and western Japan) cannot adequately be explained only by the abrupt 15Ma rotation of ...

Single Piezometric Stress Preserved in Strained Feldspar and Quartz From Intracontinental Lower Crust

Tectonics, Volume 45, Issue 3, March 2026.
Abstract The strength of the intracontinental lower crust exerts a primary control on regional‐scale deformation during continent‐continent collision. Because of the nominally anhydrous nature of much of the intracontinental lower crust, it is generally considered to be more viscous than lower crust in hydrated tectonic margins.

The Rwenzori Mountains, a Paleoproterzoic crustal shear belt crossing the Albertine rift system [PDF]

, 2015
This contribution discusses the development of the Paleoproterozoic Buganda-Toro belt in the Rwenzori mountains and its influence on the western part of the East African Rift System in Uganda.

The Magnetic Signature of Stress in Rocks

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Magnetic signatures preserved in rocks have long provided insight into Earth's evolution, revealing processes from plate tectonics to the habitability of Earth. While large impacts are known to impose extreme stresses (>1 GPa) and heat that fundamentally alters magnetic records, lower stresses typical of earthquakes have been considered ...

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

The Mesozoic-Cenozoic tectonic evolution of the New Siberian Islands, NE Russia [PDF]

, 2014
On the New Siberian Islands the rocks of the east Russian Arctic shelf are exposed and allow an assessment of the structural evolution of the region. Tectonic fabrics provide evidence of three palaeo-shortening directions (NE–SW, WNW–ESE and NNW–SSE to ...

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.
