Stratigraphy
Lithology and environment
| Primary lithology: | "cross stratification" lithified sandstone |
| Secondary lithology: | bioturbation lithified siltstone |
| Lithology description: The lower part, about 130 m thick, consists of very fine- to fine-grained hummocky cross-stratified sand- stone and bioturbated siltstone. The sandstone fines southwestward, and changes to bioturbated sandy siltstone, which contains calcareous nodules. | |
