Lithology and environment
| Primary lithology: | lithified packstone | ||
| Lithology description: crinoidal packstone and grainstone with small micritic fistuliporoid bioherms | |||
| Environment: | offshore ramp | Tectonic setting: | foreland basin |
| Glacial or sequence phase: | highstand systems tract | ||
| Geology comments: 2003:04:06: SEP sequence call based on assumption of colelction from Rockway Member (lower Irondequoit). If collection from upper Model City Member, then sequence should be TST (see Brett et al. (1998). Silurian Cycles. Bulletin NY state museum 491, p. 108).
NOTE: environmental call here of "reef, buildup, or biohermal" may be stretching it a bit. Probably should be offshore carbonate ramp so I have changed it. | |||
