Antarctic Record of Gondwana BreakUp and Dispersal of the Southern Hemisphere Continents

This section addresses the 180 Ma to recent time window during which present-day Antarctica and the other southern continents and surrounding oceanic basins formed as a consequence of the fragmentation of Gondwana, and the tectonic processes involved in the drift and dispersion of the various continental fragments. After a general overview of the most significant plate tectonic stages and coeval magmatic products, the attention is devoted to one of the most investigated regions in Antarctica, the Transantarctic Mountains and the Ross Sea sector of the Western Antarctic Rift System.
