虽然对于沿着埃塞俄比亚裂谷(Ethiopian Rift)的切变或横切该裂谷的主要延伸还没有证据。红海和亚丁湾的扩张史仍应当是非常相似的。为了检验这点,对这二个地区的磁异常剖面作了化极处理,以便于直接地进行对比。检验的结果似乎表现出一些很显著的差别,并讨论了出现这些差异的可能原因. Although there is no evidence of a major extension of or along the Ethiopian Rift along the rift. The expansion history of the Red Sea and Gulf of Aden should still be very similar. In order to test this point, the magnetic anomaly profiles of the two regions were optimized for direct comparison. The test results appear to show some significant differences and discuss the possible causes for these discrepancies.
