Nature of Palaeozoic extension in Lofoten, north Norwegian Continental Shelf: insights from 3-D seismic analysis of a Cordilleran-style metamorphic core complex
Analyses of 3-D seismic data reveal that pre-Triassic basins are present underneath the Mesozoic North Træna Basin (Lofoten Margin, Norway). These are linked to a Cordilleran-style metamorphic core complex that developed in Palaeozoic times, including rotated fault blocks with hanging wall ‘growth’...
