Abstract
[EN]Caution should be applied to the interpretation of aeromagnetic data since often they use unknown geological bodies of unknown characteristics to explain the anomalies. A case study in the Lugo Sanabria Extensional Dome (NW Spain) shows that what was interpreted as an anomaly sourced by a basic/ultrabasic magnetic body from the lower crust/mantle, seems to be related to magnetization along extensional detachments in relation to the orogenic evolution of a thickenend Variscan crust.
