在红海，洋壳最初侵位在规则间隔的“热点”，作为核轴向传播到洋壳增生的片段和海底扩张的开始，发生从大陆到洋裂谷的过渡。在大陆裂谷和大洋裂谷下的密度/粘度反转引起的上涌地幔底辟之上形成热点。
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.
