通过对华北地台河南鹤壁地区太原组有孔虫动物群的系统研究，共鉴定出有孔虫化石18属33种，建立了一个区域性有孔虫动物组合带：Bradyina-Palaeotextularia组合带，根据有孔虫化石的属种类型、数量，应用数理统计方法得出组合带有孔虫化石在地层中的比例变化情况，并根据化石组合带与国内其它地区的有孔虫动物群进行对比研究，认为鹤壁剖面有孔虫动物群Bradyina-Palaeotextularia组合带归于晚石炭世晚期的早期（C22-1），进而对研究区石炭-二叠系界线的划分进行探讨，界限应该放在第16层（泥岩）和第15层（灰岩）之间。

Through the systematic study of Taiyuan Formation foraminiferal fauna in Hebi area, Henan on the North China platform, total-ly identified foraminiferal fossils 33 species in 18 genera, established a regional Bradyina-Palaeotextularia assemblage zone. Based on foraminifera genus and species types, quantity, using mathematical statistics derived proportional variation of foraminiferal fossils in stra-ta and carried out contrastive study with other area foraminiferal fauna in China. Finally figured out that the Bradyina-Palaeotextularia assemblage zone on Hebi section belongs to earlier late stage of Late Carboniferous Epoch. Furthermore, carried out a discussion on Permian Carboniferous boundary in the area;deemed that the boundary should be put between layer No.16 (mudstone) and layer No.15 (limestone).
