Lithology and environment
| Primary lithology: | black calcareous,cherty/siliceous mudstone |
| Lithology description: "The lithology is thinly bedded, cherty, black, bituminous, calcareous mudstone." | |
| Environment: | offshore shelf |
| Geology comments: "Level-bottom carbonate shelf...BA 4-5...It is possible that it was deposited in inter-carbonate mound basins of no great lateral extent, in which circulation was restricted; such an environment of deposition is also presumed for all Otarion and Aulacopleura dominated assemblages." | |
