Abstract

Previous studies, carried out by the “Trieste and Cagliari University”, within the Italian "Programma Nazionale di Ricerche in Antartide" on the Straits of Magellan were mainly directed at sedimentological research on the sea bottoms and coastal belt of the eastern section (Atlantic opening). Subsequent research along the coastal belt was carried out in greater detail with mapping of morpho-sedimentologicalogical units. During this second phase, greater attention was given to the study of palaeo-shorelines and different terrace orders of presumed marine and transitional origin (Brambati et alii 1993, De Muro et alii 1995). On the basis of the initial geomorphological, and sedimentological results obtained, we made a zoning of the coastal belts along the Atlantic opening of the Straits which enabled us to print 12 sheets on a scale of 1:50,000 (De Muro et alii 2004). Morphogenesis of the area was strictly controlled by the processes associated with the advance and retreat of the Magellano Glacier and, subordinately, by the main morphodynamic event represented by post deglaciation marine ingression. The Holocene paleogeographic evolutionary picture of the Patagonia-Tierra del Fuego area is mainly controlled by the imposing phenomenon of glacio-isostasy, though it cannot be ruled out that the morphogenesis subsequent to deglaciation may have been affected by mild neo-tectonic movements. The Atlas provides a zoning of the area distribution of the most significant Holocene marine and transitional deposits processes and forms relating to the coastal belt between P.ta Dungeness and Cabo Froward
