Closed‐form stress solution and minimum safe burial depth correction for shallow‐buried large‐diameter energy storage chambers

Deep Underground Science and Engineering, EarlyView.
This study develops a closed‐form solution for stress analysis of shallow‐buried large‐diameter compressed air energy storage (CAES) chambers, explicitly incorporating free surface, lateral pressure, and gravity gradient effects. Validated against numerical simulations, the solution accurately captures stress redistribution and reveals upward migration

Evidence for structural control of mare volcanism in lunar compressional tectonic settings

Nature Communications, 2023
One of the long-standing enigmas for lunar tectonic-thermal evolution is the spatiotemporal association of contractional wrinkle ridges and basaltic volcanism in a compressional regime.

Morpho-tectonic evolution of the Çanakkale Basin (NW Anatolia): evidence for a recent tectonic inversion from transpression to transtension [PDF]

Geo-Marine Letters, 2011
Onshore and offshore seismic and geologic-morphologic evidence from the wider region of the Canakkale Basin indicates that this area has been widely exposed to transpressional tectonism, which already commenced in the Pliocene. During this transpressional tectonism, the Gelibolu Fault and the Anafartalar Shear Zone on the Gelibolu Peninsula, as well as

Intelligent inversion analysis of dilatancy angle of surrounding rock based on the force of negative Poisson's ratio anchor cable

Deep Underground Science and Engineering, EarlyView.
An intelligent inversion framework estimates the dilatancy angle of the surrounding rock from negative Poisson's ratio (NPR) anchor cable force histories. Numerical tunnel‐excavation simulations generate force data across a controlled dilatancy‐angle range, which are mapped to the target parameter using a sequential convolutional neural network (CNN ...

Fracture Development Mechanism of Water‐Isolating Soil Layers During Downward Mining of Shallow‐Buried Coal Seam Groups

Energy Science &Engineering, EarlyView.
This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Tectonic Stylolite Stress Inversion, Angle Correction, Validation Across Scales and Variability Within Outcrops

Geosciences
Quantitative stylolite roughness inversion technique (SRIT) is a powerful tool that is increasingly used to determine burial depth and tectonic stress of rocks that contain stylolites. Despite the increasing use of SRIT, there is still a need to validate

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]

, 2010
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Tectonic evolution and mineralization exploration of Lujing uranium ore field, South China

Scientific Reports
Granite-type uranium deposit is one of the most important uranium deposit types in China, with orebodies strongly controlled by structures. Previous studies of the Lujing ore field mainly focused on metallogenic genesis and Yanshanian structure, which ...
