Formation of a new oceanic lithosphere
WebThe 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 discontinuous … WebFind many great new & used options and get the best deals for Ophiolites: Ancient Oceanic Lithosphere? by R.G.
