WebDec 5, 2024 · Modeling of gravity data suggests the crust beneath rift segments is intruded by dense, likely mafic rock, and that the crust is thinner (e.g., Tiberi et al. 2005; Lewi et al. 2016). Some regions of the Afar Depression have already subsided below sea level, suggesting strongly that seafloor spreading is imminent in Afar (Fig. 1).

The dynamic life of an oceanic plate - ScienceDirect

WebTransition from a continental to an oceanic rift occurs in the Red Sea by initial emplacement of oceanic crust in regularly spaced ‘hot points’, which serve as nuclei for axial propagation into segments of oceanic crust accretion and for initiation of seafloor spreading. Hot points develop above upwelling mantle diapirs caused by density / viscosity inversion beneath … WebEarly estimates for a 5 Ma onset of sea floor spreading in the Red Sea were based on magnetic anomalies preserved in exposed oceanic crust, and were therefore limited to areas of the Southern Red Sea unobstructed by overlying thick successions of sediment and salt deposits ( Courtillot, 1982; Cochran, 1983; Almalki et al., 2016 ).
