| 摘 要： | 西康群等岩群的研究已取得初步成果,由于构造变形复杂,至今沉积地层层序等基本问题尚未解决。运用沉积地质学理论,从造山带演化观点出发,对海底扁和滨、浅海沉积等关键问题进行了讨论,提出盆地演化的初步设想,并就今后研究提出了若干意见,以促进该项研究工作的深入发展。

| Abstract: | Some achievements in the research on the Xikang Group in west Sichuan have been yielded. But, owing to the complex nature of tectonic deformation, such basic problems as sedimentary stratigraphic sequence remain to be settled. In the light of viewpoint of evolution of the orogenic zone, we apply theory of sedimentology to the discussion of key problems such as submarine fan, littoral and neritic deposits. Our tentative ideas of basin evolution and some suggestions for further research have been put forward. |
