 note = {Petrographical study of sedimentary rocks from the Middle Permian Gufeng Formation in the Chaohu area, Anhui Province, China, has been carried out. The Gufeng Formation is subdivided into the Phosphate nodule-bearing mudstone Member (PNMM) and the Siliceous rock Member (SRM). The basal part of the PNMM consists of mudstone including pellets of glauconite which form in the aerobic shallow marine water. The upper part of the PNMM consists of phosphate nodule-bearing mudstone. The presence of phosphate nodules suggests the deposition in the anoxic slightly deep marine environment (e.g. outer shelf). The SRM consists of alternating beds of chert and mudstone, including abundant radiolarians and organic matter. Chert of the upper part of SRM includes silicified shell fragments which can be considered as shallow marine origin. The results suggest that the deposits of the Gufeng Formation records one transgressive-regressive cycle in the Maokouan time., 国立情報学研究所で電子化したコンテンツを使用している。},
