Sedimentary characteristics and geological significance of reef-shoal deposits in carbonate shelf settings: a case study of the Upper Permian Changxing Formation in the Mianyang–Yanting area, northwestern Sichuan Basin

Conventional views suggest deep-water, low-energy deposition in intra-platform depressions, limiting exploration in transitional zones. However, new data from the Pengxi–Wushen area reveal extensive high-energy reef-shoal complexes along the carbonate ramp margin during the Changxing Stage. This study characterizes the...
