| 摘 要： | 对孙吴一嘉荫盆地北部逊克县的嘉DI井采集的孢粉和沟鞭藻类化石进行了分析研究，划分出?个特征较明显的孢粉组合：富饶组Betulaepollenires-Schizaeoisporites-Polypodiaceaesporites组合，总体反映晚白垩世晚期Maastrichtian期的特点；太平林场组Gothanipollis-Gabionisporis-Balmeisporites组合，时代为晚白垩世Santonian—Campanian期；淘淇河组上段Hammenia-Taxodiaceaepollenites-Appendicisportes组合，时代为早白垩Aptian—Albian期；淘淇河组下段Cicatricosporites-Cyathidites-Osmundacidites组合，时代为早白垩Valanginan—Barrcmian期。这是迄今该地区据钻井实际资料所发现的较连续孢粉组合序列。 |

| Abstract: | Abundant palynomorphs and dinoflagellate fossils were collected systematically were gained from the Jia D1 well,45 km to the southwest of Xunke Town, Heilongjiang,China. Four palynological assemblages were recognized in descending order:Betulaepollenites-Schizaeoisporites-Polypodiaceaesporites assemblage from the Furao Formation may represent the characters of Maastrichtian. The age of Gothanipollis-Gabonisporis-Balmeisporites assemblage from the Taipinglinchang Formation might be Santonian-Campanian. Hammenia-Taxodiaceaepollenites-Appendicisporites assemblage from the upper member of Taoqihe Formation might be Aptian-Albian in age and Cicatricosisporites-Cyathidites-Osmundacidites assemblage distributed in the lower member of Taoqihe Formation might be aged in Valanginian-Barremian. |
