Abstract
    The Porcupine basin is a deep sedimentary basin on the continental margin west of Ireland. All available geologic and geophysical data have been used to interpret the history of the basin. It contains up to 8 km of Cretaceous and younger sediments, underlain by an unknown thickness of Jurassic and Triassic rock. Gravity and magnetic anomaly models have been used to investigate the nature of the crust. Regional geologic and geophysical studies show that the Porcupine basin was originally structured in the early Mesozoic as part of a complex northeast to north-northeast-trending intracontinental rift system extending from the Grand Banks of Newfoundland to the present northwest Europe continental shelf.
