The SW Iberian margin is an oblique passive margin developed during the Mesozoic, as part of the opening of the westernmost Ligurian Tethys. The Algarve Basin developed on the SW Iberian margin and its sedimentary record was strongly controlled by tectonics. The Algarve Basin was dominated during the Mesozoic by WSW–ENE trending extensional faults and their associated depocenters, segmented by oblique NW–SE transfer zones. Two major NW–SE trending transfer zones connected the Algarve Basin to the Gorringe Bank in the west and to the Betic Basin in the east. The SW Iberian margin was later inverted during Late Cretaceous to Cenozoic times, due to convergence between Africa and Iberia. Inversion of the Algarve Basin and the SW Iberian margin was controlled by both the WSW–ENE and NW–SE trending structures formed during the passive margin phase. The evolution of the Algarve Basin during the Mesozoic and up to the Paleogene is documented in this paper through paleogeographic reconstructions based on field geology and reinterpretation of offshore seismic and well data.
