Incipient seafloot spreading segments
WebFeb 3, 2024 · Seafloor spreading propagated from south to north starting in Cretaceous times in distinct phases that involved the following regions: Newfoundland–Iberia, North America–Porcupine, North America–Greenland (Labrador Sea and Baffin Bay), Greenland–Eurasia and Lomonosov Ridge–Eurasia (Eurasian Basin, Arctic Ocean) (Fig. 1) … 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 ). WebDec 1, 2015 · In this study, we aim to investigate inheritance of continental rifting on incipient seafloor spreading by modeling the complete rifting–spreading process, with particular attention paid on the two oceanic accretion modes (symmetric and …
WebMid-ocean ridges are segmented and offset along their length. However, the kinematics of rift linkage and the initiation of oceanic transform faults in magmatic rifts remain debated. Crustal deformation patterns from the Afar continental rift provide evidences of how rifts grow to link in an area of incipient seafloor spreading. Here we present examples of rift … WebDOI: 10.1016/J.TECTO.2014.01.030 Corpus ID: 129410344; Episodic sea-floor spreading in the Southern Red Sea @article{Almalki2014EpisodicSS, title={Episodic sea-floor spreading in the Southern Red Sea}, author={Khalid A.
