An analytical solution of direction evolution of crack growth during progressive failure in brittle rocks

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 452-460, September 2025.
A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing

Gas migration at the granite–bentonite interface under semirigid boundary conditions in the context of high‐level radioactive waste disposal

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 422-436, September 2025.
A series of water infiltration tests and gas permeability tests were conducted on granite and granite–bentonite samples. According to the results, the interfaces between granite and bentonite and the damaged granite were considered to be the preferentcial pathway for gas migration.

Oblique Arc–Arc Collision During the Earliest Permian in the Northern Beishan Orogenic Collage, NW China: Constraints From Transpressional Deformation and Geochronological Data

Tectonics, Volume 44, Issue 8, August 2025.
Abstract Understanding the deformation history and mechanisms is important for inferring orogenic processes and dynamics. We present new structural and geochronological data from the Pengboshan area in the eastern part of the Heiyingshan–Hanshan Arc (HHA), northern Beishan Orogenic Collage (BOC), to constrain the Carboniferous–Permian deformation ...

Research on the Closure Polarity of the Paleo‐Asian Ocean: Evidence From the Three‐Dimensional Lithospheric Resistivity Structure of Central Asian Orogenic Belt

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.
Abstract The Central Asian Orogenic Belt (CAOB) is a Phanerozoic accretionary orogen with a complex formation process. This study imaged the three‐dimensional electrical structure of the lithosphere using the magnetotelluric data collected covering the southern margin of the CAOB. The resistivity model shows alternating high and low resistivities along
