| 摘 要： | 岐口凹陷新近系包括明化镇组和馆陶组.通过新近系中的孢粉、介形虫和遗迹组构的系统研究, 识别出孢粉53个属种, 并建立了两个孢粉组合, 分别为Magnastites (粗肋孢) -Ulmus (榆粉) -Taxodiaceae pollenites (杉粉) 组合和Polygonaceae-Chenopodiaceae组合; 发现介形虫12个属种, 介形类以金星介科分子为主, 少数湖花介科分子, 以壳形单一、壳壁薄、表面光滑的类型为主, 表现了典型的非海相淡水介形类面貌; 划分出4种遗迹组构类型, 分别为Scoyenia遗迹组构、Skolithos遗迹组构、Palaeophycus遗迹组构和强扰动组构.在此基础上, 探索了生物与环境的关系, 划分了A、B、C、D、E5种生物-遗迹相带, 分别代表泛滥平原、蓄水注地或泛滥平原小型湖、河道及水下分流河道边部、滨浅湖和前三角洲沉积环境.

| Abstract: | Sporopollen,ostracod and ichnofabric characteristics of Neogene in the Qikou depression were studied and fifty-three genus were recognized.Two sporopollen combination,Magnastites-Ulmus-Taxodiaceaepollenites and Polygonaceae-Chenopodiaceae,were established.Twelve genus ostracod were identified.The ostracod shell is singleness,thin and slippy,which exhibites the visage of typical freshwater ostracod.Four ichnofabric were identified,which are Scoyenia ichnofabric,Skolithos ichnofabric,Palaeophycus ichnofabric ... |
