| 摘 要： | 对南海与大洋盆地条带状磁异常的相关分析表明，相关系数为０．１１—０．６５９，存在弱线性关系。这从一个侧面反映出边缘海洋壳与大洋壳本质上的差异。边缘海洋壳是玄武岩浆侵入并吞蚀破碎的大陆边缘地壳后形成的不同于大洋壳的新型洋壳。南海盆地磁异常显示其洋壳是新老不一、厚薄不匀的新洋壳的拼合叠覆体。

| Abstract: | From dependency analyses on linear magnetic anomalies of the South China Sea and the ocean, their related coefficients counted 0. 11-0. 659, indicating a low linear relation. From one side this reflects a difference between the properties of the marginal sea crust and ocean crust. The marginal sea crust is another kind of oceanic crust,which was formed after the basalt magma engulfed and devoured the tattered continental margin crust. The magnetic anomalies of the South China Sea Basin indicate that its oceanic crust without uniformity in age and thickness belongs to the new type of oceanic crust that was formed by piecing and superimposing. |
