宁夏沙巴台晚石炭世—早二叠世含煤地层和植物群

对宁夏石嘴山沙巴台地区晚石炭世晚期—早二叠世早期含煤地层和植物群进行了研究，共鉴定植物化石１２属１７种，划分了２个植物化石组合，即晚石炭世晚期ＬｅｐｉｄｏｄｅｎｄｒｏｎｓｚｅｉａｎｕｍＮｅｕｒｏｐｔｅｒｉｓｏｖａｔａ组合和早二叠世早期ＴａｅｎｉｏｐｔｅｒｉｓｍｕｃｒｏｎａｔａＡｎｎｕｌａｒｉａｏｒｉｅｎｔａｌｉｓ组合，其代表地层为晚石炭世晚期的太原组和早二叠世早期的山西组；此外，还讨论了含煤地层植物群的特征和时代．

COAL BEARING STRATA AND FLORA OF LATE CARBONIFEROUS AND EARLY PERMIAN IN THE SHABATAI AREA, NINGXIA

The coal bearing strata and flora of late Late Carboniferous and early Early Permian in the Shabatai area of Shizuishan, Ningxia are studied. The flora of the coal bearing strata is composed of 17 species in 12 genera, which can be divided into two fossil plant assemblages in ascending order as follows: the late Late Carboniferous Lepidodendron szeianum Neuropteris ovata Assemblage and the early Early Permian Taeniopteris mucronata Annularia orientalis Assemblage. Their typical formations are the Taiyuan Formation and the Shanxi Formation respectively. In addition, the characteristics and geological ages of the flora of the coal bearing strata in this area are also described.
