| Abstract: |
| The South China Sea is the largest marginal sea of west Paicfic Ocean.Its valuable to the continental margin.The evolution of Tethyan structure is a very important part of the evolution of the South China Sea.Its formation is due to a sequence opening and closing of Tethys Ocean loke a horn,and made violent influence to the evolution history of the global geologic strcture.When Gondwana continent separated from Euro-Asian continent in the norh,there produced a series of small oceanic basins. The fromation of new oceanic basin was in company with the extinction of the older ones. This recyeling of new oceanic basin was in company with the extinction of the older ones. This reaycling function made the formation of a huge strucfor successive continental margin and oil-gas exploring. Furthermore, it is impirtant for discovering the relationship brtween Tethyan realm and Pacfic realm. In this paper,the authors have done 3 gravtational models basing on deep crustal research,and they want to discuss the reace of Tethyan structure in the northern slope of the South China Sea. |
