ON THE LOWER PERMIAN SPOROPOLLEN ASSEMBLAGE AND PETROLEUM SIGNIFICANCE INTHE SOUTHERN TANGSHAN, HEBEI PROVINCE
-
摘要: 唐山南部早二叠世山西组、下石盒子组的地层中发现了较丰富的孢粉化石。据孢粉组合特征,自下而上划分为两个孢粉组合,即光面单缝孢-匙唇孢-煎叶抱组合,光面单缝孢-费氏粉-双囊花粉组合。第一组合时代为山西组,第二组合为下石炭统石盒子组。并将它们和国内同时期的孢粉组合进行了比较和讨论。Abstract: A plenty of sporopllen fossils been discovered in the Shanxi Fr and the lower section of the Shhezi Fr. within the Lower Permian System in the Southem Tangshan, Accoring to the sporopollencharacters from bottom to top, the sporopollen assemblage can be divided into two subassemblages as theLaevigatosporites-Gul isporitespal midites and the Laevigatosporites-Florinites-Disaccites. The geological age of the first subassemblage is attributed to the Shanxi Fr.,while that of the second one should be theShihezi Fr. of the Lower Carboniferous System. The correlation of the sporopollen assemblages with thoseof same ages in our country are discussed in this paper.
