Geological Evolution of Antarctica is a collection of papers presented at the Fifth International Symposium on Antarctic Earth Sciences, held under the auspices of the Scientific Committee on Antarctic Research (SCAR) at Robinson College, Cambridge, 23–28 August 1987. Contributors were invited to address problems related to the tectonic evolution of the Antarctic crust and the palaeoenvironmental evolution of Antartica since the Late Mesozoic. One hundred and seventy two papers and posters were presented, of which one hundred and fifteen are included in this volume. Papers dealing with the crustal development of Antarctica are divided into major geographical areas and arranged in chronostratigraphic order. The first four sections in this group cover the craton, the Transantarctic Mountains, Weddell Sea-Ross Sea region and the Pacific margin; the last addresses aspects of Gondwana break-up. A final group of papers discusses some of the environmental changes arising from the break-up of
