| 摘 要： | 本文用四种方法计算了南海的岩石圈厚度,并建立了南海海盆的岩石圈均衡模型。在此基础上,分析了南海海盆的岩石圈结构特征:即从海盆中部向南、北两侧,层3厚度、地壳厚度和岩石圈厚度逐渐增大,与地壳年龄呈正向关系。这表明,南海海盆有如大洋(大西洋)一样的形成演化机制—由正常的裂谷和扩张过程发育而成。

| Abstract: | The thickness of lithosphere in South China Sea was catculated by using four methods, and the lithospheric isostatic model of South China Sea Basin was established. Based upon the above mentioned study, the characteristics of the lithospheric structure of South China Sea Basin, e.g. the thickness of layer 3, crust and lithosphere are considered to have increased from the center of the basin to both the north and south, indicating a positive relation with the erustal age. This illustrates that the function of formation and evolution of South China Sea Basin is similar to that of the ocean(Atlantic), which might be developed in the sequence from normal rift to the spreading process. |
