Lithology and environment
Primary lithology: | gray,white lithified marl |
Secondary lithology: | coarse,pebbly,phosphatic,black,green lithified calcareous conglomerate |
Includes fossils? | Y |
Lithology description: two units are described, from bottom to top: (1) coarse conglomerate of green and black phosphate pebbles with sandstone and quartz pebbles cemented by lime; (2) white and grayish-white marl containing some fossils | |
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. |
