| 摘 要： | 辽西南票地区山西组，共发现孢粉２１个属４７种。组合特征是蕨类植物孢子占优势，为孢粉总量的９７．４％；裸子植物花粉含量很少，仅占２．６％。根据孢粉含量及其在垂直方向上的变化，本组合自下向上划分成两个组合带：Ｓｉｍｏｚｏｎｏｔｒｉｌｅｔｅｓ－Ｓｉｎｕｌａｔｉｓｐｏｒｉｔｅｓ；Ｓｉｎｕｌａｔｉｓｐｏｒｉｔｅｓ－Ｌａｅｖｉｇａｔｏｓｐｏｒｉｔｅｓ。

| Abstract: | The miospore assemblages are discovered from Shanxi formation in Nanpiao Area,Western Liaoing,including 21 genera and 47 species.These assemblages are characterized by the dominace of pteridophyte spores,which occupy 97 40% of the total content,with a small amount of gymnospermous pollen occupying 2 6%.These sporopollen assemblages may be divided into 2 zones in ascending order as follows: 1 Simozonotriletes Sinulatisporites;2 Sinulatisporites Laevigatosporites . |
