摘要
Using the basic principles and methods of sedimentology and sequence stratigraphy, combining field measurements with indoor microscopic study, and applying drilling data to correlating data of regional sequence stratigraphy, the authors studied and summarized sedimentary facies characteristics, sequence stratigraphy and lithofacies paleogeography distribution of Upper Permian Changxing Formation in Pingtang, Guizhou Province. The results demonstrate that three kinds of sedimentary environments exist in Upper Permian Changxing Formation, i.e., open platform, shoal of platform margin and inter-platform basins. The Changxing Formation of the study area can be divided into two third-order sequences of PSQ1 and PSQ2, and both are composed of the transgressive systems tract (TST) and the highstand systems tract (HST), with the thickness of TST larger than that of HST.
