Summary
In this study, the petrographic characteristics and distribution of volcanic
rocks of the superior cenozoic in the South Shetland Islands are discussed.
The geology of the Coppermine Peninsula, on Robert Island, Potter Peninsula on
King George Island, Bridgeman Island, Penguin Island and Deception Island is
detailed . The evolution of the pleistocene-recent volcanic ... centers bound to
the tectonic depression of the Bransfield Strait and the recent eruptions on
Deception Island are analyzed.

En Espanol:
En este trabajo se discuten las caracteristicas petrograficas y distribucion de
las rocas volcanicas del cenozoico superior en las Islas Shetland del Sur,
Antartica. Se detalla la geologia de Peninsula Copper Mine, Isla Robert, Potter
en Isla Rey Jorge, Bridgeman, Penguin y Decepcion. Se analiza la evolucion de
los centros volcanicos pleistocenico-recientes ligada a la depresion tectonica
del Estrecho de Bransfield y las recientes erupciones ocurridas en Isla
Decepcion.

Quality
Petrographic and chemical analyses were conducted on the collected samples.
Silicon dioxide (SiO2) content, indices of color, and hypabyssal equivalence
were determined. The modal composition of igneous rock samples on Robert
Island and Potter Peninsula was determined. Lava modal composition of
Bridgeman Island, Penguin Island, Deception Island and Howling ... Island was also
determined. Topographic maps and geologic schemas appear in addition to the
study areas.

Las muestras recolectadas fueron sometidas a analisis petrograficos y quimicos.
Fue analizado el contenido de SiO2, indice de color y equivalencia hipabisal.
Se determinp la composicion modal de rocas igneas de la Isla Robert, Peninsula
Potter. Composicion modal de lavas de la Isla Bridgeman, Isla Penguin, Isla
Decepcion, Isla Bramante. Se presentan ademas Mapas topograficos y Esquemas
geologicos de las areas de estudio.
