本文通过系统采样,利用化学浸泡法,对冀北坳陷凌源地区和宣龙坳陷北京延庆地区的雾迷山组疑源类进行了研究,并划分出四个化石组合,自下而上分别为:罗庄组合(Asperatopsophosphaera umishanensis-Oscillatori-opsis luozhuangensis)、磨盘峪组合(Stictosphaeridium pectinale-Micrhystridium pallidum)、二十里堡组合(Pale-amorpha punctulata-Orygmatosphaeridium rubignosum)和闪坡岭组合(Microconcentrica cymata-Baltisphaeridium cerinum).通过两个地区疑源类组合特征的对比,认为凌源地区和延庆地区雾迷山组微疑源类化石组合及特征具有可对比性.

On the basis of systematic sampling and chemical soaking treatment,a large amount of acritarches were found from the Wumishan Formaton of the middle Jixian system of the early Mesoproterozoic in Lingyuan area of eastern Yanshan range and Yanqing area of western Yanshan rang.They could be distinctly subdivided in-to following four assemblages preliminarily,namely the Luozhuang assemblage(Asperatopsophosphaera umisha-nensis—Oscillatoriopsis luozhuangensis),the Mopanyu assemblage(Stictosphaeridium pectinale—Micrhystridi-um pallidum),the Ershilipu assemblage(Paleamorpha punctulata—Orygmatosphaeridium rubignosum)and the Shanpoling assemblage(Microconcentrica cymata—Baltisphaeridium cerinum)in ascending order.Comparative study indicates acritarch assemblages possess considerable comparability and the potential of stratgraphic corre-lation.
