Lee Creek Mine, Yorktown Formation (Pliocene of the United States)

Where: Beaufort County, North Carolina (35.4° N, 76.8° W: paleocoordinates 35.4° N, 75.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Yorktown Formation (Chesapeake Group), Zanclean (5.3 - 3.6 Ma)

• most fossils "are derived from the lower beds of the Yorktown Formation" (McLellan 1983) and the "total thickness of the Yorktown exposure is 15 m" (Snyder et al. 1983)

•Strontium dating places the base of the Yorktown Formation at 4.9 Ma [55]. The top of the Yorktown Formation at Lee Creek Mine is no younger than the middle of the Orionina vaughani ostracod assemblage zone, originally dated to ca. 3.7 Ma [53]. This is roughly in agreement with the top of nannoplankton zone NN14 (3.9 Ma) [20, 54], the second of the three nannoplankton zones correlating with the Orionina vaughani zone [53]. Taken together, these observations indicate an age bracket of 4.9–3.9 Ma. (Marx & Fordyce, 2015)

• member-level stratigraphic resolution

Environment/lithology: estuary or bay; unlithified, blue, argillaceous, muddy sandstone

• the lower part of the formation in the Lee Creek Mine was deposited in an embayment "at depths of 80 to 100 meters" whereas "in the Lee Creek Mine, middle beds of the Yorktown accumulated in water of 30 meters or less" (Gibson 1983)
• bluish clayey sand

•"The Yorktown Formation at Lee Creek... is generally a very muddy quartz sand... shell material and cemented sediment comprise less than 3 percent of

•most samples" although there is a "boulder bed" at the top of the formation and a single zone of "extensively leached, partially indurated zone that contains abundant molds of turritellid gastropods and cemented clumps of sediment (Snyder et al. 1983)

Size classes: macrofossils, mesofossils, microfossils

Preservation: original phosphate

Collection methods: bulk, salvage, surface (float), sieve

• "Most [large] fossils are collected by prospecting the spoil piles" (McLellan 1983) but forams were collected through bulk sampling and washing with detergent and not acid (Snyder et al. 1983)
