摘　　要：赤峰盆地是一个晚侏罗世晚期发展起来的陆相断陷盆地,主成盆期为早白垩世。盆地内沉积盖层包括了上侏罗统兴安岭群、下白垩统义县组、九佛堂组、沙海组、阜新组,以及孙家湾组。作者首次比较完整地介绍了赤峰盆地早白垩世岩石地层层序及孢粉化石组合序列,并对各地层单元的区域对比关系和地质时代归属进行了简要讨论。Chifeng basin is a continental downfaulted basin which developed from late Jurassic,and the mainly basining period was in the early Cretaceous. The depositional cap beds in the basin included a group of late Jurassic (Xinganling Group) and 5 Formations of early Cretaceous (Yixian, Jiufutang, Shahai, Fuxin and Sunjiawan Formation). Comparatively it is the first time that the stratigraphic sequence in Chifeng Basin is introduced completely in this paper, and the spore-pollen assemblages have been set up. At the same time, correlation and the geologic period of the stratigraphic units have been discussed.
