摘要
本文根据中法1985年2—3月在南中国海中部进行的地质、地球物理调查所计算的磁异常理论剖面与南海条带状磁异常进行了对比和分析,确定了南海海盆的扩张年龄,这对于进一步探讨南海海盆的形成和演化有着十分重要的意义。
The South China Sea Basin belongs to the ceased active marginal basin in the most of the western pacific Ocean, which was formed by sea-floor spreading. A successful investigation on geology and geophysics was made by both scientists of China and France in South China Sea in February-March, 1985. In this paper, the sea-floor spreading age of this basin can be determined on the basis of contrast and analyses for the theoretical p-rofiles of magnetic anomalies calculated and the anomalies of magnetic lineations obtained. This is of importance to approach the formation and evolution of the South China Basin.
