Palaeocene - Eocene deltaic sedimentation, Porcupine Basin, offshore Ireland - a sequence stratigraphic approach

The Porcupine Basin, a Mesozoic to Cenozoic ensialic N-S oriented basin, lies in deep North Atlantic waters (150 m in the north to over 1500 m in the south) on the continental shelf off the west coast of Ireland (Naylor and Shannon 1982). It is bounded to the north by the Slyne Ridge, to the west by the Porcupine Ridge, to the east by the Irish Mainland Shelf and it merges with the Goban Spur to the south (Fig. 1). The basin is divided by an E-W basement ridge into a small North Porcupine Basin and a large Main Porcupine Basin
