The Permian of the Jingxian and Nanling regions in Anhui Province are well developed, mainly consisting of carbonate, siliceous rocks, and siliciclastic. The Permian Chuanshan Formation belongs to shallow carbonate platform facies. In the Chihsia Formation, the basal siliciclastic member belongs to littoral swamp facies, the fetid limestone member, and the lower and upper siliceous limestone members were deposited in the middle part of carbonate slope, the middle limestone member belongs to shallow open carbonate platform, and the uppermost limestone member was deposited in the upper slope facies. The Gufeng and Dalong Formations were deposited in anoxic environments in deep basin to basin margin facies. The Wuxue Formation was deposited in carbonate platform facies, and the Yinping Formation belongs to littoral lagoon facies. The Longtan Formation with interbedded marine and nanmarina units was deposited, mostly in delta environments, including om delta front facies and delta plain facies, and the bioclastic limestone of the uppermost Longtan Formation in Jingxian belongs to open carbonate platform facies. The Permian strata involves three transgression and two regression cycles, with transgressions occurring in the early Qixian, early Maokouan and early Changxingian Stages, and regressions in the terminal Chuanshanan and terminal Maokouan stages. At the Qixia Stage includes two transgression and regression sub-cycles.
