东地中海（克里特岛以东）和华南海盆是被大陆块包围的小洋盆，目前正在关闭。它们都是由大陆碎片从大型大陆上断裂而成的。两个盆地的地质演化的比较表明，在两个盆地发生的演化阶段的顺序显着的相似性，虽然这些阶段的年龄可能是不同的两个。这两个盆地的形成是一个更大的过程的结果，在这个过程中，盆地南部和北部的大型岩石圈板块相互移动：非洲，包括西奈半岛和阿拉伯半岛，向欧亚大陆移动，印度-澳大利亚向欧亚大陆和太平洋移动。每个海盆都经历了几个演化阶段，在此期间，洋壳被创造和毁灭。在每一阶段，新形成的洋壳面积都小于前一阶段形成的洋壳面积。类似的演化模式似乎也发生在大陆裂谷作用形成的其他边缘和小型洋盆中。
The eastern Mediterranean (east of Crete) and the South China Basin are small ocean basins surrounded by continental masses and are currently undergoing closure. They were both formed by the rifting of continental fragments away from large continents. A comparison of the geological evolution of the two basins indicates a remarkable similarity in the sequence of evolutionary stages that took place in both basins, although the age of these stages is probably different for each of the two. The formation of the two basins is a consequence of a much larger process in which large lithospheric plates south and north of the basins move toward each other: Africa, including Sinai and Arabia, toward Eurasia and India-Australia toward Eurasia and the Pacific. Each basin went through several stages of evolution during which oceanic crust was created and destroyed. During each stage the area of the newly formed oceanic crust was smaller than the area formed in the previous stage. It appears as if similar evolutionary patterns also occurred in other marginal and small ocean basins formed by continental rifting.
