摘要
中国地层委员会2014年发布的《中国地层表》,在年代地层和岩石地层划分等方面和原地层表相比都有很大变化,作者在对该表进行初步解读的基础上,将冀北侏罗系与其做了对比,以期引起广大同行的关注和重视。作者认为:河北省北部的下花园组时代应由早—中侏罗世改为中侏罗世,层位与西山窑组一致;南大岭组与八道湾组层位相当;九龙山组和髫髻山组的层位相当于头屯河组;后城组时代为晚侏罗世,同层位地层是土城子组;张家口组划归下白垩统。
The Stratigraphic Chart of China was published by All China Commission of Stratigraphy in 2014. Compared to the last Stratigraphic Chart, it has changed very substantially in the matter of chronostratigraphic and lithostratigraphic classification. The author has compared Jurassic stratigraphy in north Hebei with the Chart on the basis of preliminary study, and expect to cause the extensive attention among the peers. The author holds that: the age of Xiahuayuan Formation in Northern Hebei Province should be changed from Early—Middle Jurassic to Middle Jurassic, and the horizon is consistent with the Yaopo Formation in Western Hill of Beijing; the horizon of the Nandaling Formation and the Badaowan Formation is the same; the layer of the Jiulongshan Formation and the Tiaojishan Formation correspond to the Toutunhe Formation; the age of the Houcheng Formation is Late Jurassic, and the horizon is the same as the Tuchengzi Formation; the Zhangjiakou Formation should belong to Lower Cretaceous.
