Sequence-Stratigraphic Framework of the Early to Middle Triassic and Evolution of Sedimentary-Facies and Paleogeography in the Nanpanjiang Basin and Its Adjacent Areas: Discussion on Evolutionary Process from the Dianqiangui Basin to the Nanpanjia
A large-scale drowning event occurred in the transitional period between the Permian and the Triassic and resulted in the demise of some carbonate platforms in the Nanpanjiang Basin and its adjacent areas. The research areas experienced an evolutionary process of sedimentary basin from the Dianqiangui Basin to the Nanpanjiang Basin in the Triassic. Accordingly, the Triassic period is a differential period of sedimentary facies in the research areas, which are marked by the spatial changes from the connectiv...
