Stratigraphy
| Formation: | Castle Hayne | ||||
| Stratigraphy comments: LITHOSTRATIGRAPHIC RELATIONSHIPS: Castle Hayne Limestone. AGE: Eocene, according to Miller (1947); Bartonian, according to Kier (1980). STRATIGRAPHIC POSITION: From unknown position in section. |
Lithology and environment
| Primary lithology: | lithified "limestone" |
| Lithology description: LITHOLOGY: Three facies in ascending stratigraphic order: phosphate pebble biomicrudite, bryozoan biosparrudite, bryozoan biomicrudite. LITHIFICATION: Lithified, on the basis of facies description and specimen preservation. | |
| Environment: | deep subtidal ramp |
| Geology comments: ENVIRONMENT: 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. | |
