Norway offshore - Lista and Kristiansand volcanic areas controlled by 3D interactive magnetic modelling

Following the regional high sensitivity aeromagnetic surveys performed by NORGES GEOLOGISKE UNDERSOEKELSE (NGU) in 1974-75 for oil exploration and re-processed by AMAROK in 1989-90, it has been possible to identify and reconstruct the most important anorogenic volcanoes of the Lower Tertiary (Paleocene) in the passive margin of the southern Norwegian offshore, covering an area of approximately 27,000 Km2•
