The Castle Hayne Limestone (also called the Castle Hayne Formation) is a middle Eocene-aged geologic formation in North Carolina, USA.[1] It consists of cobble to pebble sized clasts, usually rounded, coated with phosphate and glauconite in a limestone matrix. The formation has been dated to the middle Eocene, but its exact age remains uncertain; however, it is generally thought to date to the Lutetian or early Bartonian.[2]
