| Summary: | Summary Glacial erratics containing sparse spores and pollen derived from a suite of glaciogene strata hidden beneath the Antarctic Ice Sheet have been found in the Grove Mountains, east of the Lambert Glacier drainage system, Antarctica. The assemblage includes angiosperm and gymnosperm taxa of possible Neogene age with a minor recycled component. The miospores differ from those described from several other Cenozoic Antarctic localities, but include some similar taxa to the Pliocene Meyer Desert Formation. As a primary conclusion, we suggest that the occurrence of these pollen assemblages present new evidence for a large scale glacial retreat event in the Grove Mountains of east Antarctica. |
