Lithology and environment
| Primary lithology: | lithified dolomite | ||
| Secondary lithology: | gray,green lithified "shale" | ||
| Includes fossils? | Y | ||
| Lithology description: In western New York and Ontario the basal Rockway Formation consists of argillaceous dolostone and gray, dolomitic shale, with a sparse, poorly preserved Costistricklandia fauna. The Rockway Formation changes facies in west-central New York to greenish-gray shale and dolostone previously assigned to undifferentiated lower Irondequoit, and still farther east to the sandy Dawes Dolostone. | |||
| Environment: | offshore ramp | Tectonic setting: | foreland basin |
| Glacial or sequence phase: | transgressive systems tract | ||
| Geology comments: This assemblage represents offshore, well oxygenated mud bottom conditions.
