| Summary: | The Celtic Sea area, offshore southern Ireland, is underlain by several discrete rift basins, part of a larger set of such basins which developed marginal to the North Atlantic within the tectonic framework of Pangea break-up and episodic opening of the North Atlantic Ocean. This study investigates tectonic processes of rift basin formation by analysis of the structural and stratigraphic evolution of the Celtic Sea basins, with particular emphasis on the influence of preexisting crustal structure on that evolution. The Paleozoic Caledonian and Variscan orogenies each imprinted distinct structural grains on this area, and the intersecting pattern of these tectonic lineaments provided the structural framework for the subsequent Triassic, Late Jurassic and Early Cretaceous rifting phases. Detailed study of the largest basin in the area, the North Celtic Sea Basin, using an extensive well and seismic database, indicates that the mode of reactivation of these preexisting lines of structural weakness depended on ... |
