摘要:通过对山东省淄博地区太原组小有孔虫类动物群的系统研究,共鉴定出小有孔虫11属22种及部分未定种。根据有孔虫类化石在地层中的分布和垂向变化规律,建立了两个小有孔虫化石组合带:IBradyina-Plectogyra组合与IITetrataxis-Nodosaria-Palaeotextularia组合。通过与邻区及华中华北其它地区的有孔虫进行对比,并结合前人对本区类化石的研究结果,确定了各组合带的地质时代:太原组小有孔虫动物群第1组合带地质时代归为晚石炭世,第ⅡI组合带地质时代归为早二

Abstract: Through the systematic study of the foraminiferal fauna of the Taiyuan Formation in Zibo, Shandong Province, we have identified 11 genera, 22 species, and some undetermined species of small foraminiferal fossils. Based on the spatial distribution and stratigraphic variation in the foraminiferal fauna, two small foraminiferal assemblages are established from the bottom to the top, i.e., BradyinaPlectogyra assemblage and TetrataxisNodosariaPalaeotextularia assemblage. By comparing our fossil data with the foraminiferal fauna in the nearby regions and other areas in Central China and North China, and combining the previous results of fusulinid fossils, we have estimated the geological ages of the two fossil zones. The geological age of the BradyinaPlectogyra assemblage should be Late Carboniferous, and the geological age of the TetrataxisNodosariaPalaeotextularia assemblage should be
Early Permian, So the CarboniferousPermian boundary in Shandong Province lies at the bottom of Pseudoschwagerina zone. Key words: Taiyuan Formation; foraminiferal fauna; CarboniferousPermian boundary; Zibo; Shandong Province
