Abstract

The study area extends from the margin of the Wright Upper Glacier to the east end of the Dais and includes the Labyrinth, the Dais and the North and South Forks. The AA. suggest that a wet-based glacier overrode the area and deposited what has been mapped elsewhere as the Peleus till. The Wright Upper Glacier, an outlet glacier of the East Antarctic Ice Sheet, deposited lateral moraines and lateral-moraine segments along the north and south walls of both the North and South Forks following deposition of the Peleus till. The AA. propose a correlation of glacial deposits, and discuss the implications of the chronology on palaeoclimate reconstruction
