Lithology and environment
| Primary lithology: | wave ripples,red lithified sandstone |
| Includes fossils? | Y |
| Lithology description: Mixed lithofacies: sand content 10-90%, transitionally increasing from the base to the top of the sets. This facies consists of a close spaced alternation of red pelite and sandy storm layers a few centimetre thick. | |
| Environment: | shoreface |
| Geology comments: The sedimentary environment was a shallow shelf. | |
