Punctiform initiation of seafloor spreading in the Red Sea during transition from a continental to an oceanic rift

  title={Punctiform initiation of seafloor spreading in the Red Sea during transition from a continental to an oceanic rift},
  author={E. Bonatti},
Transition 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 continental and oceanic rifts. 
Northern Red Sea: Nucleation of an oceanic spreading center within a continental rift
[1] The northern Red Sea is an amagmatic continental rift in which an oceanic spreading center is beginning to develop. A new compilation of marine geophysical data permits delineation of theExpand
Birth of an ocean in the Red Sea: Oceanic-type basaltic melt intrusions precede continental rupture
Abstract The role of magmatism in continental rupture at the birth of a new ocean is poorly understood. Continental rupture can take place with voluminous volcanism, as in the southern Red Sea, or inExpand
The Northern Red Sea in Transition from Rifting to Drifting-Lessons Learned from Ocean Deeps
The transition from continental rifting to seafloor spreading can be observed along the 2,000 km length of the Red Sea Rift system. Whereas the southern Red Sea shows seafloor spreading since 5 MaExpand
Constraints on the deformation and rupturing of continental lithosphere of the Red Sea: the transition from rifting to drifting
Abstract The Red Sea is an ideal locale for testing differing models and hypotheses for rift evolution and the initiation of sea-floor spreading. The Red Sea is an active rift system that formed byExpand
Seafloor Spreading Initiation: Geophysical and Geochemical Constraints from the Thetis and Nereus Deeps, Central Red Sea
The rifting apart of continents involves interaction of tectonic and magmatic events that reflect the strain-rate and temperature-dependent processes of solid state deformation and decompressionExpand
Incipient seafloor spreading segments: Insights from the Red Sea
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”Expand
The nature of upper mantle upwelling during initiation of seafloor spreading in the southern Red Sea
The response of the mantle and specifically melt generation during the progression from continental to oceanic rifting is poorly understood due to an absence of direct observations. Specifically, itExpand
Oceanization Starts at Depth During Continental Rupturing in the Northern Red Sea
We present here 3D seismic reflection and gravity data obtained from an off-axis area of the NW Red Sea, as well as results of a study of gabbroic rocks recovered in the same area both from an oilExpand
Evidence from the northern Red Sea on the transition from continental to oceanic rifting
Abstract The northern Red Sea is an active rift in the last stages of continental rifting which is beginning to undergo the transition to oceanic seafloor spreading. The rift can be divided into twoExpand
The rifting to spreading transition in the Red Sea
Highlights • The Red Sea Rift (RSR) comprises the typical terrain of slow MOR axes seen elsewhere. • Submarine salt glaciers occur extensively along the RSR and blanket parts of the RSR. •Expand


Propagating rifts and continental breakup
A simple quantitative model is proposed whereby continental breakup starts with a phase of continental rifting and continues with the propagation of rifts toward locked zones. These zones areExpand
Plate Tectonics of the Red Sea and East Africa
It seems impossible to close the gap of the Red Sea without leaving the space required for this continental block, so some of the assumptions and results of a recent letter by McKenzie et al. are commented on. Expand
Volcano spacings and lithospheric attenuation in the Eastern Rift of Africa
Abstract The Eastern Rift of Africa runs the gamut of crustal and lithospheric attenuation, from undeformed shield through attenuated rift margin to active neo-oceanic spreading zones. It isExpand
The Rio Grande Rift and a Diapiric Mechanism for Continental Rifting
Continental rifts have been characterized by en echelon valleys which average 50 km in width, are bounded by extensional normal faults and act as crustal lineaments of great length transecting broadExpand
Red Sea Floor Origin: Rare-Earth Evidence
Results imply that a similar magmatic process, related to spreading of sea floors, operates beneath the axial trough of the Red Sea and the crest of mid-ocean ridges. Expand

Abstract Results of a recent detailed survey of the axial trough of the Red Sea are used to obtain the present instantaneous kinematic pattern over the whole Red Sea—Gulf of Aden area. This patternExpand
Two Stage Red Sea Floor Spreading
Evidence is presented which strongly suggests that most of the southern Red Sea is underlain by oceanic crust which evolved in two stages, the first from about 41 to 34 million years ago and theExpand

Summary. The ‘magnetic quiet zone’ in the eastern Gulf of Aden is located between the oceanic crust of Sheba Ridge and the continental crust of Arabia and Somalia, and is separated from both byExpand
Some remarks on the development of sedimentary basins
A simple model for the development and evolution of sedimentary basins is proposed. The first event consists of a rapid stretching of continental lithosphere, which produces thinning and passiveExpand
