| 摘 要： | 本文运用露头层序地层学方法，以贵州威宁哲觉剖面为基础，首次将该区晚二叠世沉积的陆相煤系地层宣威组划分为两个三级层序，介绍了其层序界面和三类副层序，探讨了层序界面与地层界线之间的关系和层序体系域与煤层聚集之间的关系。

| Abstract: | The Xuanwei formation, terrestrial coal measure strata to deposits in late Permian, was divided into two three_grade sequences by the method of outcrop sequence stratigraphy, basing on the Zhejue section in Weining, Guizhou. Their sequence boundaries and three types of parasequences have been described. Inside, relations between sequence boundaries and stratigraphic boundaries, system tracts of sequence and vertical distribution of coal bed, were discussed. |
