The North Atlantic Igneous Province - NAIP (Thulean Volcanic Province) - comprises large volumes of intrusive and extrusive igneous rocks. These were emplaced during crustal thinning and subsequent continental break-up and initial phases of seafloor spreading, associated with the rifting and opening of the North Atlantic between Greenland and NW Europe. The NAIP is now dismembered by the opening of the North Atlantic, with elements represented in Baffin Island (Canadian Arctic), west and east Greenland, the Faroe Islands, and in northern and western parts of the British Isles and adjacent offshore areas (Saunders et al. 1997). Igneous activity extended from latest Cretaceous to Middle Eocene, but was most intense during two phases, in the mid-Paleocene and around the Paleocene-Eocene boundary. Its wide extent, predominantly mafic composition and extensive subaerially erupted flood basalts qualify the NAIP as a Large Igneous Province (LIP) or Continental Flood Basalt Province (CFBP) (Saunders et al. 1997).

A revised correlation of Tertiary rocks in the British Isles and adjacent areas of NW Europe
This Special Report comprehensively describes the stratigraphy and correlation of the Tertiary (Paleogene-Neogene) rocks of NW Europe and the adjacent Atlantic Ocean and is the summation of fifty years of research on Tertiary sediments by Chris King. His book is essential reading for all geologists who deal with Tertiary rocks across NW Europe, including those in the petroleum industry and geotechnical services as well as academic stratigraphers and palaeontologists.
Introductory sections on chronostratigraphy, biostratigraphy and other methods of dating and correlation are followed by a regional summary of Tertiary sedimentary basins and their framework and an introduction to Tertiary igneous rocks. The third and largest segment comprises the regional stratigraphic summaries. Regions covered are the North Sea Basin, on shore areas of southern England and the eastern English Channel area, the North Atlantic margins (including non-marine basins in the Irish Sea and elsewhere) and the Paleogene igneous rocks of Scotland.
