Lithology and environment
| Primary lithology: | gray lithified "limestone" |
| Lithology description: The basal interval (2 m thick) is characterized by dark grey medium to thin-layered marlstones inter-bedded with clayey shales. The thickness of these siltstone beds varies from 1 to 15–20 cm. Intercalated limestone beds contain abundant tentaculites, fish remains and conodonts. | |
