Characteristic curves for interpreting the vertical magnetic anomalies of dipping doublets

Summary Standard charts from which a complete solution of the vertical magnetic anomalies of dipping doublets can be obtained very rapidly are derived and presented. The most important distances to be scaled from the field profile are the distances between the maximum and minimum anomalies, half maximum anomalies and one-third maximum anomalies only. The use of the charts for claculating the various parameters and locating the origin is also incorporated.
