Abstract[CAT] Aquesta Tesi estudia els processos de rifting i acreció ocehnica en les conques de rere-arc utilitzant dades de batimetria multifeix i dades geofisiques. Els metodes geofisics emprats han estat, principalment, magnetisme i gravimetria, tot i que també es presenten dades de sísmica de reflexió i de submergible. Tres arees han estat seleccionades: les conques Central i Oriental a la Conca de Bransfield, 1'Eix d'Expansió Central, i la Dorsal de Sud Pandora-Tripartita a la Conca Nord-Fijiana.
[EN] This Thesis deals with the study of the rifting and seafloor spreading processes in backarc basins using swath-bathymetry and geophysical data. The geophysical methods used are mainly magnetics and gravity, although other methods, such as seismic reflection and submersible data are also presented in some chapters. Three areas were selected for this study: The Central and Eastern Bransfield Basins, northwest Antarctic Peninsula, and the Central Spreading Ridge and the South Pandora-Tripartite Ridges in the North Fiji Basin, southwest Pacific.
