ABSTRACT

Marion Island is at present located only 2° latitude north of the Antarctic Convergence. Besides former palynological and geological proof for a glaciation of Würmian–Wisconsin age, further evidence has been found to indicate that Marion has been subjected to glaciations of both Würm and Riss age. Large areas of drift have been recognised for the first time together with a number of glacial landforms. Work so far undertaken suggests that there was a central ice cap from which a number of glaciers radiated. Till fabric analysis, striation observations and landforms have enabled a reconstruction of the glacier distribution on the northeastern side of the island to be undertaken.

The evidence from Marion is compared with that from other sub-Antarctic islands and from ocean floor sediments. The relationship of the findings to the Quaternary climate of the island is suggested. Evidence for sea level changes is also given and compared to that found on other sub-Antarctic islands.
