Lithology and environment
| Primary lithology: | lenticular,"cross stratification",fine,yellow poorly lithified sandy sandstone |
| Secondary lithology: | gypsiferous,red sandy claystone |
| Includes fossils? | Y |
| Lithology description: "...soft sandy sandstones, very porous, with cross-stratification. Their color varies from pale yellow to brick red; the grain is rather fine, but the banks can present locally thicker passing lenses with rare quartz pebbles. Finally, one observes equally several intercalations of red sandy clay with traces of gypsum." | |
