Tectonic Stress as the Driving Mechanism for Dike Opening in an Oblique Rift Setting: A Deformation Model of the 2021 Fagradalsfjall Dike, Iceland

Geophysical Research Letters
Repeated dike‐intrusions often occur in zones where extensional stress has accumulated. Still, geodetic modeling of observed dike‐induced ground deformation often ignores the contribution of tectonic stress. On the obliquely spreading Reykjanes Peninsula,

Research status of tectonic stress and the relationship between tectonic stress and oil-gas accumulation

IOSR Journal of Engineering, 2014
In oil-bearing basins, the relationship between tectonic stress and generation, migration, accumulation of oil and gas has been a research focus in the oil and gas dynamics. This paper takeed the research status of tectonic stress as the foothold, and the research methods of tectonic stress as foundation, summarized the effects of tectonic stress on ...

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Integrating Remote Sensing, Archaeological Survey and Geophysical Prospections for the Enhancement of Roman Doclea, Montenegro

Archaeological Prospection, EarlyView.
ABSTRACT The Roman city of Doclea is a key archaeological site of Montenegro, valued for its impressive remains and its role in the nation's cultural identity within European and the Mediterranean history. Doclea was the second‐largest city in the province of Roman Dalmatia, a municipium created in the first century ad and named after the Illyrian ...

Study on the Influence of Tectonic Stress on Stability of Horseshoe-Shaped Tunnels

Advances in Materials Science and Engineering, 2021
While the tunnel is in the high tectonic stress environment and surrounding rock of tunnel has the characteristics of soft texture and stronger expansion, the preference of tunnel shape is horseshoe.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Present-day stress state of the Shanxi tectonic belt

Geodynamics & Tectonophysics, 2012
The Shanxi tectonic belt is a historically earthquakeabundant area. For the majority of strong earthquakes in this area, the distribution of earthquake foci was controlled by the N–S oriented local structures on the tectonic belt. Studies of the present stress state of the Shanxi tectonic belt can contribute to the understanding of the relationship ...

Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Tectonic, depth, and magnitude controls on global earthquake stress drop

Solid Earth Sciences
Earthquake stress drop is a key parameter linking fault strength, rupture dynamics, and high-frequency ground motion, yet global observations exhibit variability spanning more than two orders of magnitude.
