Approximate calculations have been made of the magnitude and form of anomalous masses required to account for the residual gravity anomalies over four diapiric structures in northern Spain. The Orduña diapir has a simple negative anomaly and apparently is caused by a salt intrusion. The Sobrón anticline and the Salinas de Añana diapirs have strong negative anomalies with central positive features; large salt masses apparently caused the negative effects, and intrusions of igneous material, the positive anomalies. The Murguía diapir has a simple, positive anomaly probably caused either by a massive igneous intrusive body which may have replaced a preexisting salt intrusion or by a relatively shallow, lenticular sill.
