Abstract

It is suggested that the Scotia Arc was formed after the disruption of a continental strip between South America and Antarctica by an eastward advance of the Pacific crust; volcanic island arcs and associated trenches developed at the juction of the Pacific and Atlantic crustal types; the Scotia Arc migrated eastward with time; and that the crustal structure of the Scotia Sea is in the process of changing from an oceanic (Pacific) to a continental type.
