Lithology and environment
| Primary lithology: | gray argillaceous,cherty/siliceous "limestone" | ||
| Lithology description: "dark-gray to black fine-grained to medium-grained argillaceous limestone. Finely crystalling calcite forms one-half to two-thirds of the rock. The less calcareous layers are weakly cleaved. There are discontinuous layers and nodules of ligh-gray-weathering and dark-gray to black chert. Much of the shelly material in the rock is silicified." | |||
| Environment: | open shallow subtidal | Tectonic setting: | foreland basin |
| Geology comments: Grades into overlying New Scotland Formatiion
