Lithology and environment
| Primary lithology: | concretionary,gray poorly lithified argillaceous lime mudstone |
| Includes fossils? | Y |
| Lithology description: gray argillaceous calcilutite | |
| Environment: | deep subtidal shelf |
| Geology comments: upper part of an 8 m bed that "was soft and poorly indurated" with "small concretions""relatively shallow but open water. A shelf environment is inferred...""Aragonitic mollusks and anthozoans are preserved either as external or internal molds, but calcitic shells appear unaltered" | |
