本文记述了湖南南部嘉禾、常宁及耒阳等地三个二叠纪地层剖面,将本区二叠系划分为:上统包括大隆组、小元冲组:下统包括斗岭组(即斗岭煤系)、当冲组及栖霞组等地层单位。其中着重讨论了斗岭煤系的时代问题。在斗岭组顶部采得大量Altudoceras,Paraceltites等菊石化石,时代属早二叠世晚期,从而提出了本区斗岭煤系时代应属早二叠世晚期。文中的
This paper describes the three Permian stratigraphic sections of Jiahe, Changning and Xingyang in southern Hunan, and divides the Permian in this area into: the upper strata include the Dalong Formation and the Xiaoyuan Chong Formation: the lower reaches include the Douling Formation Douling coal series), when the red group and Qixia formation unit. The discussion focused on the times of Douling coal series. A large number of ammonite fossils such as Altudoceras and Paraceltites were collected from the top of the Dulingling Formation, which belonged to the late Early Permian. Therefore, it is proposed that the coal-bearing age of Douling in this area should belong to the late Early Permian. In the text
