Resumen

The tectonic evolution of the Scotia Arc since Oligocene has developed a complex array of stretched and submerged continental blocks together with small oceanic basins.The evolution of the main southern Scotia Seabasins, which allows deep circulation from Weddell to Scotia seas, reached roughly the present configuration in Middle-Upper Miocene. The most recent oceanic gateways, as Bruce Passage or Deep Basin in Discovery Bank, are deep extensional basins associated with the sinistral transcurrent fault zone of the Scotia-Antarctic plate boundary, formed from Upper Miocene to present.
