Tectonic interactions during rift linkage: insights from analog and numerical experiments [PDF]
Solid Earth, 2023 Continental rifts evolve by linkage and interaction of adjacent individual segments. As rift segments propagate, they can cause notable re-orientation of the local stress field so that stress orientations deviate from the regional trend.
