摘要(Abstract)：
通过对农１０１ 井９６ 块孢粉样品的分析鉴定， 划分了２ 个孢粉组合带， 即ＤｅｌｔｏｉｄｏｓｐｏｒａＣａｙｔｏｎｉｐｏｌｌｅｎｉｔｅｓ、Ｃｌａｓｓｏｐｏｌｌｉｓ 组合带和Ｃｉｃａｔｒｉｃｏｓｉｓｐｏｒｉｔｅｓ、ＤｅｎｓｏｉｓｐｏｒｉｔｅｓＰｉｎｕｓｐｏｌｌｅｎｉｔｅｓ、Ｐｉｃｅａｅｐｏｌｌｅｎｉｔｅｓ 组合带， 并在分析其特征的基础上， 确定了所属的地质时代。最后， 讨论了与相邻地区的对比问题。
This paper analyses 96 pieces of sporopollen sample from Well Nong 101 and plots out 2 sporopollen composition zones,i.e.Deltoidospora Caytonipollenites,Classopollis Zone and Cicatricosisporites, Dansoisporites Pinuspollenites, Piceaepollenites Zone.Based on the analysis of their characteristic, it determines their geologic time and discusses their comparison with the adjacent area.
