The objectives of this study were to simplify the stratigraphic nomenclature and establish a unified regional stratigraphic classification and framework. To achieve an effective stratigraphic analysis, it was essential to recognise the correct level and method of correlation. Seismic-sequence stratigraphy represents the most practical approach to subdividing and correlating the Neogene succession on a regional basis, as this technique produces the most realistic stratigraphic correlation over large geographic areas, especially in frontier regions such as the NW European Atlantic margin. The seismic-sequence stratigraphic concept used follows the Geological Society's guide to stratigraphic procedure (Whittaker et al. 1991). The basis of the method is to use an integrated geological/geophysical database to define the sedimentary record in terms of depositional sequences. Emphasis has been placed on the establishment of megasequences, which bring together units that constitute important genetic packages. This level of mapping was deemed most appropriate in the establishment of a regional framework, as the development of megasequences tends to reflect major changes in continental margin evolution.
