摘　　要：山东滕县上石炭统—二叠系含煤地层中发现大量保存良好的孢粉化石属种及部分未定属种。根据孢粉化石主要属种的纵向分布规律及含量的变化,建立了本区五个孢粉组合带,自上而下为:V.Triquitrites-Macrotorisporacathayensis;IV.Patellisporitesmeishanensis-Torisporasecuris;III.Gulisporitescerevus-Sinulatisporitesshanxiensis;II.Thymosporapseudothiessenii-Laevigatosporitesvulgaris;I.Crassisporakosankei-Densosporitesanulatus。它们自上而下分别代表了本区晚古生代二叠系石盒子统上石盒子组、下石盒子组和月门沟统山西组、太原组上段以及上石炭统太原组下段。本文简述了各孢粉组合的特征,并与邻区及华北部分地区进行了对比;另外,还论证了滕县煤田晋祠组的存在。Abundant and well-preserved miospores are recovered from the coal-bearing Upper Carboniferous Permi- an strata in Tengxian, Shangdong. On the basis of identification and statistics, five assemblages have been recognized, in desending order：Ⅴ. Triquitrites-Macrotorispora cathayensis ;Ⅳ. Patellisporites meishanensis Torispora securis; Ⅲ. Gulisporites cerevus Sinulatisporites shanxiensis; Ⅱ. Thwnospora pseudothiessenii Laevigatosporites vulgaris ; Ⅰ. Crassispora kosankei- Densosporites anulatus. The miospore assemblages V to I are derived from the Upper Shi- hezi Formation, the Lower Sbihezi Formation, the Shanxi and the Taiyuan Formation respectively, and their characteristics are discussed. Correlation of these assemblages with other known assemblages in North China have been suggested. The existence of Jinci Formation in Tengxian coalfield is confirmed in this paper.
