Triassic prospectivity in the Celtic Sea, Ireland - a case history

The Celtic Sea region south of Ireland contains Mesozoic sedimentary basins with an ENE trend. The North Celtic Sea, St George's Channel and Fastnet basins lie north of the Pembrokeshirè-Labadie Bank ridge complex (herafter referred to as the Pembrokeshire Ridge), with the South Celtic Sea, Bristol Channel and Cockburn basins to the south (Fig. 1). The Channel and Western Approaches basins parallel the Celtic Sea basins and are separated from them by the Cornubian Massif. East of the massif the Channel Basin sweeps northwards onto the English mainland as the Wessex Basin.
