WebMar 28, 2016 · Crustal‐scale forward models of marine satellite potential field data suggest that the Red Sea comprises a single segment of ocean crust, which extends along ~60% of the Red Sea. The segment “tips” are bounded by continental crust, and there is no evidence for transforms at the segment terminations at the south. These observations indicate that … 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.

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 ). WebNov 10, 2000 · Segmentation is a characteristic feature of seafloor spreading along the global mid-ocean ridge system. While segmentation of active spreading centers has been the focus of much recent research, the process by which a rifted continental margin develops into a segmented mid-ocean ridge is still poorly understood.

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).
