| 摘 要： | 运用层序地层学的理论和方法，进行小型陆相湖盆地层研究时，发现昆明盆地存在三个超层序（二级旋回）：盆地断陷沉积超层序，盆地扩张超层序及盆地萎缩超层序。各超层序内部还可以划分2－3个层序（三级旋回）。实践证明：层序地层理论不仅可以在小型陆相湖盆中得到很好 的运用，还可以根据层序内部的体系域组成的不同区分构造层和气候层序。而且，小型湖盆的层序地层研究取得的成果，可以广泛运用于天然气勘探，构造研究等领域。

| Abstract: | Basing upon the study of sequential stratigraphic of the late Cenozoic Kunming basin in the central of Yunnan,the strata can be divided into 3 super-sequences (2nd order cycle)of lacustrine fault depression,extension and contraction.And each super-sequence can be redivided into 2 t0o 3 sequences (3rd order cycle).The sequential stratigraphic theory can apply successfully not only to a small lake basin but also to discriminating structure stratigraphic sequdnce from climate stratigraphic seauence according to the different composition of a system domain in the sequdnce.The result of sequential stratigraphic study on a small lake basin can be widely used in natural gas exploration and structure analysis,etc. |
