| Abstract: | Fossil spores and pollen are abundant at the Shenjiatun section in the Nong'an area,southeast Songliao Basin.The lithology of this section is dominated by mudstone,and referred to the Member 3 to Member 4 of Nenjiang Formation.Based on the analysis of the spores and pollen of the Shenjiatun section,the authors have identified three fossil assemblages: the Aquilapollenites-Dictyotriletes-Rugubivesiculites assemblage,the Schizaeoisporites-Classopollis-Beaupreaidites assemblage and the Rugubivesiculites-Schiza... |
