Cape Melville Fm - Hard Ground section, King George Island (Miocene of Antarctica)

Where: Antarctica (62.0° S, 57.5° W: paleocoordinates 61.7° S, 56.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cape Melville Formation (Moby Dick Group), Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From Cape Melville Fm, which conformably overlies with a sharp contact the Destruction Bay Fm, both of the Moby Dick Group. THICKNESS: From one bed within section of 10 m with formation that reaches 150 m in thickness. AGE: Early Miocene, based on consideration of radiometrics data (Troedson and Riding, 2002) and biostratigraphy (invertebrates and palynology). STRATIGRAPHIC POSITION: From single bed at base of section.

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, fine-grained, silty, sandy mudstone

• ENVIRONMENT: Stated as marine shelf setting. Suggested by Troedson and Riding (2002) to be middle-outer continental shelf.
• SPECIFIC LITHOLOGY: Specificially from sandy mudstone with dropstones and calcite layers, based on Fig. 2. In general, formation comprises interbedded silty-sandy mudstone and fine-medium sandstone and fine-medium sandstone, with subsidiary silty-sandy diamictite and thin carbonate and tuff layers. LITHIFICATION: Poorly-lithified, based on figured specimens.

Size class: macrofossils

Preservation: original aragonite

Collection methods: surface (in situ),

• COLLECTORS: Multiple collectors, not specified. REPOSITORY: Colecao Cientifica, Depatamento de Geologica Sedimentar e Ambiental, Instituto de Geosciencias, Universidade de Sao Paulo.
