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,

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 ...

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.

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.

Stress rotations and the long-term weakness of the Median Tectonic Line and the Rokko-Awaji Segment [PDF]

, 2014
International audienceWe used a field analysis of rock deformation microstructures and mesostructures to reconstructthe long-term orientation of stresses around two major active fault systems in Japan, the Median TectonicLine and the Rokko-Awaji Segment.

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.
