| Abstract: |
| The measured section of Upper Permian located at Bainapingzi, Baina Village, Dafang County is described in details. The Upper Permian in the study area is classified into the Longtan Formation and the Changxing Formation. The paper discusses their lithological association, stratigraphic contact relationship and traverse variation. A brachiopoda assemblage zone， a plant assemblage zone and a fusulinida assemblage zone have been established according to fossil association and distribution, i.e., Orthothetina rubber-Oldhamina squamosa Assemblage Zone， Gigantopteris nicotianaefolia-Gigantopteris dictyophylloidesAssemblage Zone and Palaeofusulina Assemblage Zone. Based on these zones, the Longtan Formation and Changxing Formation are Upper Permian. Sedimentary facies of the Longtan Formation have been determined as barrier coast and coastal marsh， and those of the Changxing Formation as carbonate platform based on lithological association and sedimentary structures. |
