Magda Nunatak, King George Island - Pugaczewska (1984) (Pliocene of Antarctica)

Also known as Magda Nunatak, King George Island

Where: Antarctica (62.1° S, 58.2° W: paleocoordinates 62.0° S, 57.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pliocene (5.3 - 2.6 Ma)

• Glaciomarine tillite-bearing deposits underlying basalting lavas at Magda Nunatak. These deposits have been correlated with the Polonez Cove Formation (Pliocene). According to Birkenmajer (1982) they are older than the Pliocene Polonez Cove Formation (glacial and glaciomarine sediments) and the underlying Mazurek Point Formation basaltic lavas (probably Pliocene), and belong to another glacial epoch older than thje Polonez glaciation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified conglomerate

• From glaciomarine (tillite-bearing) deposits.
• Assumed to be conglomerates as in the Polonez Cove Formation

Size class: macrofossils

Preservation: mold/impression, original aragonite

Collection methods: quarrying,

• Unknown repository
