Lithology and environment
| Primary lithology: | mudstone |
| Secondary lithology: | "cross stratification" sandy siltstone |
| Lithology description: "Alternating mudstone and sandy siltstone; groove casts and load casts; small cross laminae and convolute lamination in siltstone." | |
| Environment: | marginal marine indet. |
| Geology comments: "Waterston (1979) tentatively interprets this as a marginal marine setting. The described sedimentary features are compatible with, but not diagnostic of, a tidal flat setting. BA 1" | |
