Stratigraphy
| Formation: | Jiangdihe | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Jiangdihe Formation, Upper Cretaceous (Turonian–Santonian) (Chen, 2000).
The litho- and biostratigraphic correlation performed by the regional geological survey suggests that the Jiangdihe Formation was deposited during the Late Cretaceous (Y. Zhang, 1996), a conclusion corroborated by evidence from fossil invertebrates (conchostracans: e.g., Aglestheria, Halysestheria, Nemestheria; ostracods: e.g., Cypridea, Limnocythere) and palynomorphs that indicate the formation is Turonian–Santonian in age (Chen, 2000). The Jiangdihe Formation is conformable with both the underlying Matoushan Formation and the overlying Zhaojiadian Formation. | |||||
