A number of conflicting tectonic models have been proposed to explain the geological relationships between southern South America (Patagonia) and West Antarctica within the palaeo-Pacific margin of Gondwana. Extensive fragmentation and isolation of the various tectonic blocks during Gondwana break-u...
