Cenozoic History of the East Antarctic Icesheet - Studies of the Pagodroma Tillite and Related Strate, Prince Charles Mountains

Outcrops in the Dominion Range were visited earlier. Deposits in the Miller Range and at The Cloudmaker were not previously known.

In this report we provide briefly a review of preliminary data on Sirius Formation stratigraphy, sedimentation, and glacial history in the central Transantarctic Mountains. Other aspects of our research on the Sirius Formation presented in the 1986 review issue of the Antarctic Journal are: glacial history and tectonic relations; Dominion Erosion Surface topography; siliceous microfossil biostratigraphy and Pliocene marine environments; palynomorphs; modern southern hemisphere botanical analogs; and Pliocene terrestrial environments, flora, and biogeography.
