Abstract
Abstract Stratigraphic positions of Late Cretaceous and Tertiary floras have been established on King George Island, West Antarctica, based on K-Ar dating of associated volcanics. The oldest dated floras, of Late Cretaceous and Paleocene ages, provide evidence for a warm climate phase preceding the early Eocene glacial event termed the Kraków Glaciation. Late Eocene through early Oligocene floras indicate another warm period termed the Arctowski Interglacial, which post-dates the Kraków Glaciation. The youngest floras, of Oligocene-Miocene boundary age, indicate a temperate (or cool-temperate) climate, corresponding to the Wawel Interglacial which separated late Oligocene glacial and interglacial epochs (Polonez Glaciation, Wesele Interglacial and Legru Glaciation) from early Miocene glaciation (Melville Glaciation).
