| 摘 要： | 依据孢粉、沟鞭藻外壁成分特征，建立了一个同时获得孢粉和沟鞭藻化石的方法，在已往孢粉分析方法没获得沟鞭藻的嫩三段中分析出十分丰富的沟鞭藻化石，自下而上发现了Cyathidite-Pinus-pollenites-Dinogymniopsis , Dinogymniopsis-Leiosphaeridia-Pinuspollenites , Cicatricosisporites-Pinuspollenites-Botryoccocus , Dinogymniopsis-Chlamydophorella- Taxodiaceaepollenites , Cicatricosisporites-Pinuspollenites-Pe-diastrum, Nenjiangella-Balmula spinosa-Cyathidites, Cyathidites-Trilobosporites-Botryoccocus等7个能识别水体盐度变化的化石组合。同时指出嫩江藻在松辽盆地嫩三段范围内稳定分布，是嫩三段的标准化石；丰富的藻类化石特别是葡萄藻是最好的生油母质之一。

| Abstract: | Based on composition of outside wall of spore and pollen,dinoflagellate,a method of achieving spore and pollen and dinoflagellate simulataneously in an analysis flowsheet is designed.Through experiment repeatedly to complete the method,a very richness dinoflagellate fossil is analyzed from Nen 3 member which not achieving any dinoflagellate by traditional spore and pollen analysis method.Cyathidite-Pinuspollenit-Dinogymniopsis,Dinogymniopsis-Leiosphaeridia-Pinuspollenites,Cicatricosiporites-Pinuspollenites Botryoccocus,Dinogymniopsis-Chlamydophorella-Taxodiaceaepollenites,Cicatricosisporites-Pinuspollenites-Pediastrum,Nenjiangella-Balmula spinosa-Cyathidites,Cyathidites-Trilobosporites-Botryoccocus seven fossil assenmlages which could recognize salinity changing in water body are discovered from top to the bottom. It is also pointed out that Nenjiang algae,distributing stability,are standard fossil of No.3 member in Nenjiang Formation.Richness alga fossil,espicial grape algae is one of the best oil source rock. |
