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 ) :盆地断陷沉降超层序、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地运用 ,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
Using the theory and method of sequence stratigraphy to study the stratigraphy of the small terrestrial lacustrine basin, we found that there are three super-sequence (second-order cycles) in the Kunming basin: subsidence superposition sequence of basin faulted depression, super-sequence of basin expansion and basin atrophy Sequence. Within each super-sequence can also be divided into 2 to 3 sequences (three cycles). Practice has proved that the theory of sequence stratigraphy can not only be used well in the small continental lacustrine basin but also distinguish the structural layer and the climatic sequence according to the composition of the system tract within the sequence. Moreover, the achievements made in the study of sequence stratigraphy of small lakes can be widely applied in fields such as natural gas exploration and structural research
