The Upper Permian succession of the northern Sichuan Basin records plume-related extension within a carbonate-platform system characterized by pronounced lateral facies differentiation. However, basin-scale sequence correlation, the evolutionary history of the Kaijiang–Liangping extensional trough, the stratigraphic af...
