The spatial distribution of igneous centres along the Norwegian Atlantic Margin (Møre and Vøring) and their relationship to magmatic plumbing systems

A series of offshore intra-basinal igneous centres have been documented across the North Atlantic Igneous Province including UK, Ireland and Greenland. However, inconsistent cross-border terminology implies that similar features are not present in Norwegian offshore, which, turns, leads to misperceptions geological differences. This paper presents evidence for a suggests consistent non-genetic terminology. In Møre Basin, several sit close continent–ocean boundary (COB), which previously identified as seamounts and/or ‘outer highs’. To provide consistency these consolidated under umbrella terms: or volcanic fissures. Further probably within Basin (east COB) where 3D seismic data were available. Vøring two new centres, one intrusive extrusive, continental domain. Additionally, possible deep magmatic upwelling associated with regionally significant T-Reflector is identified. These centre end-members represent complexity plumbing margin. With further it likely will be mid-Norway.
