WebDec 1, 2015 · Overlapping spreading centers and transform faults are two common ways that oceanic segments interact ( (Gerya, 2012), and references therein). These 3D features of oceanic ridges naturally require 3D models. Furthermore, the deficit of direct natural observations makes the rifting–spreading transition enigmatic. 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 … rdo bird shooting contest
