| 摘 要： | 应用露头层序地层学基本原理和方法，在详细的岩石岩相学、沉积学研究和精细的地层划分对比基础上，对贵州宗地剖面晚石炭世二叠纪早期地层进行了露头层序地层研究。研究表明，贵州宗地剖面晚石炭世一二叠纪早期地层至少可识别出6种主要岩相及11种具有不同环境意义的微相类型。宗地剖面晚石炭世地层可以划分出6个三级层序，二叠纪早期地层可划分出4个三级层序。笔者等阐述了沉积层序的各种界面的露头标志，探讨了三级层序和层序区域对比的基本特征。三级沉积层序在不同古地理单元和不同沉积环境中可以进行对比。三级层序发育TST和HST，LST不发育或难以识别。

| Abstract: | The Late Carboniferous -- Early Permian strata outcropped in Zongdi area, Ziyun County, Guizhou Province, have four lithogenetic units with a total thinckness of 332. 01 m, are focused on detailed sedimentological study, accurate stratigraphic division and correlation in this paper. At least 6 types of lithofacies, 11 microfacies with different environment significances are recognized. The Late Carboniferous strata can be divided into 6 3rd-order sequences, named Sequence CSqS, CSq9,.. ,CSq13, respectively; and the Early Permian strata into 4 3rd-order sequences, PSql, PSq2, PSq3, PSq4, respectively. The characteristics and genesis of each third-order sequences are described and discussed. The third-order sequences in various paleogeographic units and sedimentary environment can be correlated. |
