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 … WebThe Red Sea may represent a combination of incipient type I and type II passive margins development. ... Ocean crust initiation occurs as a series of isolated segments that coalesce as the basin evolves.

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. 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 ).
