摘要
山东省中生代地层研究成果较多,但仍存在一些混乱。根据地层发育特征,本文首先将山东省中生代地层新划分为鲁西地层分区、鲁东地层分区和沂沭断裂带地层分区3个分区;然后对三叠系、侏罗系和白垩系的岩石地层单位进行了划分和对比,提出了新的地层划分和对比方案,并对鲁西地层分区白垩纪的岩石地层特征做了说明,以方便今后使用。
There has been much progresses in the research of Mesozoic strata in Shandong Province in the past decades,but some stratigraphic problems still remain unresolved.In this paper,Shandong Province is divided into three stratigraphic subregions based on their stratigraphic characters—the west Shandong subregion,the east Shandong subregion and the Yi-Shu Fracture Zone subregion.We present a proposal for the lithostratigraphic subdivision and correlation of Triassic,Jurassic and Cretaceous in these subregions.We hope that the proposed subdivision and correlation will help clarify some of the stratigraphic problerms,particularly the lithostratigraphic characters of Cretaceous in the west Shandong subregion.
