大洋型地壳

南海地壳属于大洋型地壳与大陆型地壳之间的过度类型。

The earth ′ s crust of the South China Sea belongs to the transitional type between the oceanic crust and continental crust .

琉球岛弧-海沟区的地壳结构总的来说属于过渡型地壳，但在海沟靠洋一侧已属于大洋型地壳，而从琉球海沟往东的西北菲律宾海盆，就完全属于典型的大洋地壳。

The Ryukyu arc-trench zone is belonging to the transition type crust as a whole , but the side of the trench is already belonging to the oceanic crust . And the northwest Philippines Basin to the east of the Ryukyu trench absolutely belongs to the typical oceanic crust .

南海是东亚大陆边缘的巨型陆缘海，属大陆&大洋过渡型地壳构造区。

The South China Sea is a huge marginal sea at East-Asian continental margin , and a tectonic region of the transitional crust type from continental to oceanic .
