WebMar 10, 2024 · We interpret these structures as a transition of lithospheric extension from continental rifting to oceanic spreading. The transitional lithosphere is manifested by a … WebIn geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics.. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, …

From rifting to oceanic spreading in the Gulf of Aden: a synthesis
WebDec 30, 2024 · The sequence of processes that lead from continental rifting to oceanic drifting during the genesis of passive margins remains debated. Wide-angle seismics has, over the past decades, proven an efficient tool to image the architecture and to quantify the acoustic velocity of continental margins. These data, combined with structural ... WebThe rifting of oceanic plateaus is an important mechanism for initiating lithospheric break-up and subsequent seafloor spreading. In this study, we present the latest multichannel seismic data investigating the Caroline Ridge and provide one of the typical cases for initial oceanic plateau evolution. We reveal that a smooth basement reflector ... WebApr 10, 2024 · The Central Red Sea Rift is a natural laboratory to study the transition from rifting to spreading. Based on new reflection seismic profiles and gravity modeling, we examined the crustal structure, tectonic evolution, breakup mechanism, and future evolution of the Central Red Sea Rift. Along this rift axis, the breakup of continental lithosphere is … atap keramik
