Glacial erratics on King George Is., reef facies (probably from Argentina Range) (Cambrian of Antarctica)

Also known as Reef 2372

Where: Antarctica (62.0° S, 57.6° W: paleocoordinates 19.7° S, 125.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Botomian (516.0 - 512.9 Ma)

• Cambrian limestone erratics found in the glacio-marine sediments of the Oligocene Polonez Cove and Early Miocene Cape Melville Formations on King George Island. The source area of the erratics was most probably somewhere between the Argentina Range and Theron Mountains, the age is Latest Botomian (Syringocnema favus Beds).

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks and lithified limestone

Size classes: macrofossils, mesofossils

Collection methods: peel or thin section,
