Stratigraphy
Geological group: | Clinton | Formation: | Rochester Shale | Member: | Lewiston |
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: Middle Rochester Shale (Lewiston Member, Submembers C and D) |
Lithology and environment
Primary lithology: | lithified "shale" | ||
Lithology description: dark shale | |||
Environment: | offshore | Tectonic setting: | foreland basin |
Glacial or sequence phase: | highstand systems tract | ||
Geology comments: Low to moderate sedimentation rates and a general lack of episodic burial horizons (mud tempestites), unlike other Rochester Shale assemblages. These features are consistent with a relatively low, but not bysaerobic oxygen level, and/or high turbidity environment protected from storms. |
