. Not all continental rifts mature to form a young ocean. The mechanism andduration of their cessation depend on the crustal structure, modifications inplate kinematics, lithospheric thermal response, or the intensity of subcrustalflow (e.g., plume activity). The cessation is recorded in the structure andstratigraphy of the basins that develop during the rifting process. Thisarchitecture is lost due to younger tectonic inversion, severe erosion, oreven burial into greater depths that forces their detection by low-resolutiongeophysical imaging. The current study focuses on a uniquely preservedOligo-Miocene rift that was subsequently taken over by a crossing transformfault system and, mostly due to that, died out. We integrate all geological,geophysical, and previous study results from across the southernGalilee to unravel the structural development of the Irbid failing rift innorthwest Arabia. Despite tectonic, magmatic, and geomorphologic activitypostdating the rifting, its subsurface structure northwest of the Dead Seafault is preserved at depths of up to 1 km. Our results show that a series ofbasins subsided at the rift front, i.e., rift termination, across the southernGalilee. We constrain the timing and extent of their subsidence into two mainstages based on facies analysis and chronology of magmatism. Between 20 and 9 Magrabens and half-grabens subsided within a larger releasing jog, following aNW direction of a deeper presumed principal displacement zone. The basinscontinued to subside until a transition from the transtensional Red Sea tothe transpressional Dead Sea stress regime occurred. With the transition, thebasins ceased to subside as a rift, while the Dead Sea fault split the jogstructure. Between 9 and 5 Ma basin subsidence accentuated and an uplift of theirmargins accompanied their overall elongation to the NNE. Our study providesfor the first time a structural as well as tectonic context for the southernGalilee basins. Based on this case study we suggest that the rift did notfail but rather faded and was taken over by a more dominant stress regime.Otherwise, these basins of a failing rift could have simply died outpeacefully.
