Resumen

El vulcanismo cuaternario de Isla Decepción está relacionado con el proceso de subducción y roll-back de la antigua Placa de Phoenix bajo el Bloque de las Shetland del Sur, en la Fosa de las Shetland del Sur. El desarrollo de la isla está ligado al crecimiento y colapso de una caldera volcánica, y el presente trabajo se centra en la petrología, mineralogía y geoquímica de las rocas post-caldera. Se han estudiado coladas de lava, diques y la erupción histórica más moderna de la isla (año 1970). Estas rocas varían de dacitas a riolitas y tienen texturas microporfídicas con olivino y, en ocasiones, clinopiroxeno. Además, se ha estudiado una andesita basáltica pre-caldera de textura microporfídica con clinopiroxeno. La alternancia de términos intermedios y ácidos en la secuencia volcanoestratigráfica sugiere la existencia de eventos de recarga o bien, la extracción de fundidos de diferentes profundidades del sistema magmático. Todas las muestras estudiadas comparten evidencias de subducción en la génesis de los magmas, al igual que sucede con el resto del magmatismo de la Cuenca de Bransfield. Sin embargo, los cálculos geotermobarométricos indican que los magmas pre-caldera cristalizaron en niveles más profundos (13.5–5 km) que los post-caldera (6.2–7.8 km). Mediante la comparación con los resultados disponibles de otras zonas, es posible proponer una menor influencia de la subducción en la parte suroeste de la Cuenca de Bransfield, así como cierta contaminación por corteza continental en la génesis de los magmas post-caldera.
