Lithology and environment
| Primary lithology: | fine,gray,green lithified calcareous sandstone |
| Lithology description: "Dark gray to greenish gray, fine to very fine sandstone and calcareous sandstone beds containing bioclastic concentrations characterize Facies 3. Bioclastic concentrations consist mainly of fragmented brachiopods and trilobites, and generally appear at the bases of the calcareous sandstone beds, constituting lenses and layers up to 4 cm thick. Occasionally, concentrations occur at the tops of the sandstone beds. These beds were sampled for conodonts..." | |
