山东唐口二叠纪孢粉组合特征

Characteristics of Permian PalynologicalAssemblages in Tangkou of Shandong Province

摘要:

通过对唐口二叠纪孢粉组合的分析研究，建立了该区二叠纪3个孢粉组合带，①Densosporites（套环孢）Crassispora（厚环孢）组合；②Gulisporites（匙唇三缝孢）Sinulatisporites（曲环三缝孢）组合；③Anticapipollis（逆沟粉）Macrotorispora（大一头沉孢）组合。这3个组合带分别反映太原组、山西组、下石盒子组及上石盒子组的孢粉组合面貌，其地质时代分属于早二叠世、中二叠世，晚二叠世早期。

Abstract:

Through study and analysis on Permian sporespollen assemblages in tangkou area, three Permian palynological assemblages have been established in this area. They are DensosporitesCrassispora assemblage, GulisporitesSinulatisporites assemblage, and AnticapipollisMacrotorispora assemblage.These three palynological assemblages represent characteristics of Taiyuan formation, Shanxi formation and Xiashihezi formation and Shangshihezi formation. Its geological ages belong to early Permian, middle Permian and early and late Permian respectively.
