Numerical study on instability of rock structural planes induced by stress disturbances

<title>Abstract</title> The activities in deep underground engineering may induce variations in the stress state of the rock, increasing the risk of engineering disasters. The decrease in normal stress <italic>σ</italic>_n and the increase in shear stress <italic>τ</ita...

Paleozoic Tectonic Transition from Arc–Continent Collision to Post-Orogenic Extension in the East Kunlun Orogen: Constraints from Metamorphic Events

Abstract The tectonic evolution of the trench–arc–back-–arc basin system—encompassing back-arc spreading, subduction, basin closure, and the subsequent transition from arc–continent collision to post-collisional extension—represents a fundamental process in the evolution of the P...
