Comparisons are made between the Lesser Antilles and the South Sandwich Islands, the recent volcanic island chains at the eastern margins of the Caribbean and Scotia arcs. Although situated in similar geological and structural environments there are differences in the type of volcanic activity which prevails in these two arcs and in the petrography and chemistry of the lavas emitted. There is good evidence that the South Sandwich Islands are in general appreciably younger than the islands of… 
Magmatism in the South Sandwich arc
Abstract The South Sandwich Islands are one of the world’s classic examples of an intraoceanic arc. Formed on recently generated back-arc crust, they represent the earliest stages of formation of arc
Geology, petrography, and geochemistry of the volcanic islands of Tonga
The South Pacific Ocean is an ideal area in which to test some of the compositional implications of plate tectonics and sea-floor spreading. The island arc of Tonga marks an active zone of seismic
The Scotia Arc and Antarctic Margin
The Scotia Arc is the name generally applied to the largely submarine physiographic feature that joins southern South America to the Antarctic Peninsula. More correctly called the Scotia Ridge, it
Evolution of the Margins of the Scotia Sea
The margins of the South American and Antarctic continents that border on the Scotia Sea have been affected during the Mesozoic and Cenozoic by tectonic processes related to both divergent and
Petrology and chemistry of recent lavas in the northern Marianas: Implications for the origin of island arc basalts
Petrologic and chemical data are presented for samples from five volcanically active islands in the northern Marianas group, an intra-oceanic island arc. The data include microprobe analyses of
Contrasts in tectonic evolution of orogenic belts in the south-east pacific
Abstract The orogens of southern South America and Antarctic Peninsula, which are of similar age and apparently linked by the Scotia Arc, are shown to have evolved along markedly different patterns
