Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

From Extension to Strike‐Slip Faulting Along the Western Continuation of the North Anatolian Fault in the Northern Aegean Sea: Structural, Geochronological and Geochemical Constraints

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

Fractal and 3D Modeling of the Mineralization in the Garijgan Mining Area, Eastern Iran

Journal of Economic Geology
The Garijgan mineral deposit is a classic NW-SE trending, nonparallel shear zone located 25 km south of Khousf city in South Khorasan Province, eastern Iran. The distribution pattern of fractures and ore veins was investigated by combining remote sensing,

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.

TwinCalc: A multitool for calcite twinning based stress analysis

Applied Computing and Geosciences, 2020
Calcite twining has been used and proved repeatedly as a viable stress analysis tool during past several decades, however a comprehensive multitool for stress analysis has been missing.

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 ...

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

Lithosphere
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

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 ...

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.
