| 摘 要： | 以吴家窑剖面为基础，讨论了大同煤田南部晚古生代含煤地层内植物化石的垂向分布特征。认为植物群面貌在小煤与5煤之间发生了重大改变。小峪砂岩之下发育了以Neuropterisouata为代表的早期华夏植物群；其上则出现了许多具二叠纪色彩的植物分子，如Emplectopteristriangulariscladophlebismanchuricus，TaeniopterismultinervisPrecopterisWongiiPtaiyuanensis因此，本区石炭、二叠系界线应置于小峪砂岩之底。

| Abstract: | Based on the Wuiayao Section, uertical distribution of fossil plants in late Paleozoic coal - bearing strata of Southem Datong coalfield is discussed. A obviously changes of the flora features have taken place between No. 4 and No. 5 coal seams. Under the Xiaoyu Sandstone the flora is characterized by the presence of the elements of Early Cathaysian Flora, i. e. Neuropteris ovata , etc Above it, the flora is characterized by the barge amount of the elements of Middle Cathasian Flora, i. e. Emplectopteris triangularis , Cladophlebis , Taeniopteris etc. Thus the boundare between Carboniferous and Permian should be placed in the bottom of Xiaoyu sandstone. |
