USGS 3611, 4286, 10615 (Castle Hayne rock quarry), New Hanover Co., NC (Eocene of the United States)

Where: New Hanover County, North Carolina (34.4° N, 77.9° W: paleocoordinates 34.2° N, 68.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Castle Hayne Formation, Bartonian (41.3 - 38.0 Ma)

• The Castle Hayne is described as Jackson (Eocene) in age. Age after Ward et al. 1978.

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, gray, white marl and lithified, coarse-grained, pebbly, phosphatic, black, green, calcareous conglomerate

• 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.
• 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

Size class: macrofossils

Preservation: cast

Reposited in the USGS
