ON THE LOWER PERMIAN SPOROPOLLEN ASSEMBLAGE AND PETROLEUM SIGNIFICANCE INTHE SOUTHERN TANGSHAN, HEBEI PROVINCE

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.
