摘要
冀中地区侏罗系为一套杂色含煤碎屑岩层系 ,自下而上发育有 Osmundacidites- Cyathidites- Gleicheniidites-Protoconiferus、L eiotriletes- Cycadopites- Quadraeculina- Classopollis及 Granulatisporites- L eiotriletes- Cyathidites- Cy-cadopites等 3个孢粉化石组合。冀中地区侏罗系岩性组成及化石组合特征与周边地区具有一定可对比性 ,但因其岩性具有明显的特殊性 ,故自下而上新建葛渔城组、杨村组和苏桥组。同时对冀中地区侏罗纪岩石地层系统的区域对比关系和地质时代进行了初步讨论。
The Jurassic System of the Central Hebei is a sequence of varicolored coal-bearing clastic rock series that may be correlated to a certain extent with the peripheral areas in lothological and fossil assemblage characters, and has its clear peculiarity. Thus, the Geycucheng, Yangcun, and Suqiao Formations are accendingly established. In the mean time, the regional correlation relationship of the lithostratigraphical systems of the Jurassic System of Central Hebei and the geological age are primitively discussed.
