| 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IITetrataxisNodosaria-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I组合带地质时代归为晚石炭世，第II组合带地质时代归为早二 叠世，其层位相当于山东地区太原组 类Pseudoschwagerina带之底。

| Abstract: | ThroughthesystematicstudyoftheforaminiferalfaunaoftheTaiyuanFormationinZibo,ShandongProvince,wehave identified11genera,22species,andsomeundeterminedspeciesofsmallforaminiferalfossils.Basedonthespatialdistributionand stratigraphicvariationintheforaminiferalfauna,twosmallforaminiferalassemblagesareestablishedfromthebottomtothetop,i.e., Bradyina-Plectogyra assemblage and Tetrataxis-Nodosaria-Palaeotextularia assemblage. By comparing our fossil data with the foraminiferalfaunainthenearbyregionsandotherareasinCentralChinaandNorthChina,andcombiningthepreviousresultsof fusulinid fossils, we have estimated the geological ages of the two fossil zones. The geological age of the Bradyina-Plectogyra assemblageshouldbeLateCarboniferous,andthegeologicalageoftheTetrataxis-Nodosaria-Palaeotextulariaassemblageshouldbe EarlyPermian.SotheCarboniferous-PermianboundaryinShandongProvinceliesatthebottomofPseudoschwagerinazone. |
