This method uses angles between gradients and cross-products values as criteria of correlation between maps. Applied to gravity anomaly and bathymetry this method was used to determine sources of gravity anomalies. We tested this method on synthetic model and applied to investigate the relation between free-air gravity anomaly and bathymetric maps of South-East Brazilian coast. Resulting maps were coherent with existing Bouguer anomaly and isostatic models. Method and results are discussed.
