Lithology and environment
| Primary lithology: | unlithified sandstone |
| Includes fossils? | Y |
| Lithology description: Sandstone. Unlithified based on observation of figured specimens. | |
| Environment: | coastal indet. |
| Geology comments: No paleonenvironmental data reported, though from apparently from shallow-water siliciclastic sediments. Rocks dip to the SE monoclinally away from the older sediments forming the folds of the central range of hills. From strike ridge of sandstone. | |
