| CALCULATION ON THEORETICAL PROFILES OF MAGNETIC ANOMALIES AND PRELIMINARY ANALYSES ON MAGNETIC LINEATION IN SOUTH CHINA SEA BASIN |

| Abstract: |
| 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 profiles of magnetic anomalies calculated and the anomalies of magnetic lineations obtained. This is of importance to approach the formatiion and evolution of the South China Basin. |
