Abstract
Knowledge about the Quarternary geology of the Australian sector of Antarctica is very incomplete. Scattered observations of glacial deposits in that area, made during the ANARE 6 expedition in 1987, indicate that the inland ice had formerly a considerably wider extension than today. The ice was more than 200 m thicker, probably of the order 1, 000m. This maximum stage cannot yet be dated, but conditions seem to favour a late Wisconsin-Weichselian maximum age. However, a much higher age cannot be excluded.Keywords
