| 摘 要： | 实测描绘了安徽萧县白土镇石炭纪—早二叠世的地层剖面,对剖面中采集的样品进行了磨片,并在偏光显微镜下对磨片进行了系统鉴定,共鉴定出9科16属34种,且进行了系统的描述。建立了有孔虫化石组合带Tetratax-is-Nodosaria-Palaeotextularia组合带,为晚石炭世晚期(C22)。将研究区内的有孔虫化石组合带与国内不同地区有孔虫化石组合带进行了对比,探讨了石炭纪—早二叠世有孔虫化石在地层中的分布特征,探讨了有孔虫化石对地层划分对比中的作用,认为有孔虫化石对于石炭—二叠纪的地层界线也有重要的意义。

| Abstract: | Strata sections of the Carboniferous to early Permian in Baitu section of Xiaoxian County in Anhui Province were measured and the slices were cut on the samples collected from the strata sections and identified systemically under microscope.34 species,16 genera,9 families were identified and systemically described.Based on mathematical statistical method,three fossil foraminiferal assembly zones were found in Taiyuan Formation of the area in ascending order: Tetrataxis-Nodosaria-Palaeotextularia(C22).Compar... |
