Sta. 7976 - County line road [Black Mingo Fm] (Paleocene of the United States)

Also known as Loc. 60

Where: Georgetown County, South Carolina (33.6° N, 79.4° W: paleocoordinates 34.7° N, 62.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Black Mingo Formation, Late/Upper Paleocene (58.7 - 55.8 Ma)

• STRATIGRAPHIC RELATIONS: From the Black Mingo, which presumably regionally unconformably overlies the PeeDee Fm and is unconformably overlain by the McBean Fm; the formation is laterally equialent to the Aquia Fm and the Wilcox Gp. AGE: Paleocene in text; here assigned to Late Paleocene on the basis of more recent biostratigraphic dating. STRATIGRAPHIC POSITION: From unit 2 in local section; 10 ft thick sandstone.

• bed-level stratigraphic resolution

Environment/lithology: coastal; red, conglomeratic sandstone

• ENVIRONMENT: Shallow marine, shelfal siliciclastic.
• SPECIFIC LITHOLOGY: Reddish cross-beded sand and gravel passing upward into fine brick-red sand. LITHIFICATION: Unknown.

Size class: macrofossils
