A 3D model of the temperature distribution beneath the north-eastern part of the Mid-Norwegian continental margin (the Lofoten-Vesterålen area), one of the most pronounced elevated passive continental margins in the world, has been studied to quantify the thermal influence of high erosional and depositional rates mapped during the late Cenozoic. A lithosphere-scale 3D structural/density model of the Lofoten-Vesterålen area has been used as a structural skeleton for the sedimentary infill, crystalline crust and lithospheric mantle during a 3D thermal modelling. The modelled thermal effect of the late Cenozoic erosion within the Lofoten-Vesterålen area is highlighted by a positive thermal anomaly within the areas where sedimentary and crystalline rocks were significantly eroded. A negative thermal influence has been obtained in the areas where deposition of the eroded material occurred. The erosion-related, positive, thermal anomaly reaches up to +27 oC at depths of 17–22 km. Two deposition-related, negative thermal anomalies are characterized by minimal values of around −70 oC at 17–20 km depth and −48 oC at 12–14 km depth beneath the adjacent deep ocean basin and the subsided continental margin, respectively.
