位于我国四川省东部著名的红色盆地,面积约20万平方公里。盆地内自晚三叠世晚期至老第三纪沉积了一套巨厚的陆相含煤地层及红色地层,厚数千至一万米以上。从三十年代开始,我国著名地质学家赵亚曾、黄汲清、谭锡畴、李春昱等就对这套地层进行过研究,解放后,随着对整个盆地开展区域地质、石油、煤田地质调查,对这套地层的研究又不断深入,并积累了丰富的资料。笔者近几年来(1977～1980)参加了对整个盆地的专题研究,现根据所获资料,并参阅以往成果,拟对该套地层划分作如下讨论,并在此基础上初 Located in the famous red basin in eastern Sichuan Province of China, with an area of ​​about 200,000 square kilometers. A huge set of continental coal-bearing strata and red stratum have been deposited in the basin from late Triassic to the Old Tertiary, ranging in thickness from thousands to 10,000 meters. Since the 1930s, the famous geologists in China, such as Zhao Yazeng, Huang Jiqing, Tan Xincu and Li Chunyu conducted research on this formation. After the liberation, with the geological survey of the entire basin, regional geology, petroleum and coalfields, Set of stratigraphic research has continued to deepen, and accumulated a wealth of information. In recent years (1977 ~ 1980), the author has participated in the special study of the whole basin. Based on the obtained data and referring to past achievements, it is proposed that the stratigraphic division be discussed as follows, and based on this
