This volume presents papers from a conference on 'Early Tertiary volcanism and the opening of the NE Atlantic' held in London in March 1987. They are grouped into six categories, essentially on the basis of structural and geographic setting: Volcanic and tectonic framework; Dipping reflectors and NE Atlantic evolution; E Greenland and the Faeroe Islands; Volcanism in basins to the N and W of the British Isles; British Tertiary Igneous Province; The sedimentary record.
