| Stratigraphy comments: Late Gedinnian, upper Helderbergian. | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal packstone | ||
| Includes fossils? | Y | ||
| Lithology description: "fossils occur in crinoidal packstone to grainstone facies interbedded with thin green shales" | |||
| Environment: | deep subtidal ramp | Tectonic setting: | foreland basin |
| Geology comments: "high energy shoal environment analogous to the older coeymans (Ravenna Mbr) or upper tongue of the Kalkberg Limestone; the cyclicity has long been recognized...both in terms of lithology and fauna...This is most likely an outer BA 2 to middle BA 3 community"
2003:05:03 SEP environmental call based on given description; also suspect that this is not a shoal sensu strictu given interbedded shales | |||
