Stratigraphy
Formation: | Castle Hayne | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: According to Powell and Baum, this collection may also fall under the Crassatella alta/Chlamys cawcawensis faunal zone, due to uncertainty of where the C. alta zone begins due to unconformity. |
Lithology and environment
Primary lithology: | shelly/skeletal lithified grainstone |
Includes fossils? | Y |
Lithology description: a bryozoan biosparrudite (baum et al. 1978) | |
Environment: | deep subtidal ramp |
Geology comments: The Castle Hayne Limestone was deposited in an open, normal salinity environment between 30 m and 100 m in water depth. Comfort Member contains cross-bedded intervals, suggesting some energy, consistent with deep subtidal environment. |
