山东侏罗 - 白垩纪地层划分与对比

山东中生代地层主要发育侏罗系和白垩系，沂沭断裂带以西的鲁西南、鲁中、鲁北地区发育侏罗纪至早白垩世地层，而断裂带以东的鲁东地区主要发育白垩纪地层。用古生物、火成岩年代分析结果对山东侏罗白垩系地层进行了划分和对比。将沂沭断裂带以西的坊子组归于早中侏罗世，三台组归于中侏罗世，分水岭组暂归于晚侏罗世至早白垩世，西洼组归于早白垩世；将沂沭断裂带以东的莱阳组和青山组归于早白垩世，王氏组归于晚白垩世。

DIVISION AND CORRELATION OF JURASSIC AND CRETACEOUS STRATA IN SHANDONG

The study of Mesozoic fossils and volcanic rocks in Shandong province shows that there are the Jurassic and early Cretaceous strata in the west of Yishu fracture zone (including three areas: the Southwest Shandong, the middle Shandong and the north Shandong) and mainly the Cretaceous strata in the east of this zone (namely, the east Shandong).The author considers that the Fangzi formation belongs to the lower to middle Jurassic, the Santai formation in the middle Jurassic,the Fenshuiling formation in the upper Jurassic to the lower Cretaceous, while the Laiyang formation, the Qingshan formation and the Xiwa formation belongs to the lower Cretaceous, and the Wangshi formation to the upper Cretaceous.
