Abstract

This work shows the Bouguer and aeromagnetic anomaly maps of the Iberian Chain (NE Spain) and surroundings in relation to its main geological and structural units. In general, both gravity and aeromagnetic anomalies are aligned following the same trends in both maps highlighting the major role played by the structural configuration of the Iberian Chain on their origin. In detail most anomalies do not coincide, pointing to different potential field sources to account for them. Further studies would be needed to decipher the origin of most magnetic anomalies observed in the Iberian Chain.
